Our chemistry, our values

We’ve recently launched a new set of company values for the Joseph Ash Group. They are collectively called ‘Our Chemistry’ – to reflect our excellent relationships with each other, our clients, suppliers and partners, and the chemicals we use in our galvanizing processes.

To create the values, we held several focus groups across the plants to find out what was important to our team members and what values they wanted to live by at Joseph Ash. We spoke to colleagues on the shop floor, administration and service teams at Head Office, and Commercial Teams at our different divisions. Everyone was offered the opportunity to share their thoughts on what our culture and behaviour look like when we’re at our best and what needs to be added to ensure the Joseph Ash Group thrives and grows. The resulting values are:

We thrive on team spirit, whether we’re looking out for each other’s safety or working together to meet targets. Providing help and assistance, celebrating achievements, and laughing are the elements that bind us together. We have each other’s backs.

The safety and success of our business and our future sit in our hands. We know what is expected of us as individuals and teams and demonstrate a ‘can-do’ attitude to get things done.

Growth through teaching and learning (internally and externally) is the catalyst for everything we do. We lead with experience and heritage, but we’re also enthusiastic about advancing and improving our products, processes, the industry and ourselves.

We respect each other and our differences and treat people as we want to be treated ourselves. We mix kindness with good manners and listening skills. We also appreciate family: not only in our home lives but also in the family we have at work.

If you’d like to know more – or if you’d like to join our team – please get in touch!

Galvanized lift innovation enables safe hoof care

Pigs at Beneath the Wood Sanctuary

Nestled amongst the rolling hills between Tregaron and Lampeter in Wales is an animal sanctuary called Beneath the Wood. Set up by Sasha Bennett in 2009, it provides a permanent home for dogs, sheep, cats, horses and – as of 2019 – a sounder of pigs.

The pigs (and their subsequent offspring) found safety at Beneath the Wood after they were rescued from an illegal and horrific slaughterhouse in Pembrokeshire. The 53 pigs were living in appalling conditions amongst carcasses and surviving on the entrails of the other slaughtered animals. Some were so desperate they began cannibalising. Some ate car parts, batteries, car doors… anything to avoid starvation.

After being rescued by authorities, the pigs became the subject of a court destruction order as they were not fit for consumption. There was a public outcry, so Beneath the Wood decided to fight for them. After a nine-month legal battle, the pigs (numbering 91 because the males were kept in a DEFRA isolation unit with the females!) were allowed to move to their forever home at the animal sanctuary.

Victory for Beneath the Wood and the pigs! But not without its problems.

Because the pigs had been kept in dreadful conditions at the slaughterhouse, their hooves had grown and, in some cases, become curved and uneven, making it difficult for them to stand and walk. As a result, the pigs needed a much-needed pedicure. But foot care on such heavy and strong animals is challenging. Especially when the biggest pig – Gandalf – is 7ft in length and weighs over half a tonne!

Beneath the Wood turned to Designeering in Leicestershire for help.

Designeering is a design and engineering company which helps people/companies to develop product ideas and bring them to life. The team at Beneath the Wood explained their problem. They told Designeering about animal lifting equipment such as cow hoists. A good idea, but unfortunately not suitable for the pigs. They needed lifting equipment that was strong and modular enough to accommodate different size pigs.

Designeering rose to the challenge and designed, engineered, and manufactured an innovative Pig Lift that can lift the pigs in the air with their feet dangling so they can be treated and trimmed.

They opted for a modular design that can accommodate animals ranging from 150 kg to over 600 kg. The unit is also mobile, electrically operated, and safe for the operator and animal.

As the Pig Lift consists of steel sections, tubes, and laser-cut sheet metal fabrication welded together to form a heavy-duty structure, it needed to be galvanized.

Hot dip galvanizing is imperative because it provides a long-life, low-maintenance corrosion protection, which safeguards the steel from atmospheric attack, which causes rust and weakens steel.

Hot dip galvanizing the steel pig lift

Designeering sent the Pig Lift to Joseph Ash Walsall to be treated with a galvanized coating to prolong the life of the equipment. The team at Joseph Ash were delighted to help such a good cause and donated their time and service free of charge, including collection and delivery.

The Pig Lift was delivered to the animal sanctuary just before Christmas: designed, manufactured, protected from corrosion with a galvanized finish, and ready to enable hoof trimming. The giant boars need hoof trimming first, so they’re being treated, and it’s onto the other pigs.

Sébastien de La Hamayde, Creative Director at Designeering said “We’ve loved working on this project! Sasha Bennett and her team at Beneath the Woods do a fantastic job providing a safe home for all the animals they look after. As for the pigs, despite experiencing trauma at the illegal slaughterhouse where they were found, they are now well looked after and comfortable in their new surroundings. We are proud to have designed equipment to help the Sanctuary continue looking after them.”

Paul Hudson, Sales and Technical Manager at Joseph Ash Walsall, said “Wow! What an amazing project to be involved in. Thanks to Designeering for contacting us and sending the steel to our plant. We were happy to donate our services for such a worthwhile cause. We hope the pigs thrive in their new home and the new lifting equipment gives them some much-needed care.”

Beneath the Wood Sanctuary is a not-for-profit organisation. They run solely on public donations, mainly through their Twitter, Facebook, and Instagram social media accounts. They have around 140 animals in their care, ranging from dogs, cats, pigs, horses, and sheep, all rescued from difficult circumstances. They are a small team of dedicated volunteers, just five people keeping the animals fed and cared for, along with occasional volunteer days for extra help on larger projects.

To support the Beneath the Wood team, contact Sasha Bennett via email.

Welcome to our A-Z of Galvanizing – everything you’ve ever wanted to know about galvanizing if you work with steel.

A for Acid
Pre-treating steel to ensure it is free from surface contaminants is a fundamental part of the hot dip galvanizing process, as zinc will not react to unclean metal. As part of the pre-treatment stage, steel is pickled in acid to remove mill scale and rust, producing a chemically clean surface for galvanizing.
B for Bath Sizes
Different bath sizes suit varied steel fabrications. No matter how large your steel, we can help. Across all Joseph Ash Group plants, we have a range of bath sizes to suit the smallest to the largest of jobs. Visit our bath dipping sizes page for more information.
C for Circular Economy
A circular economy encourages materials to be made, remade and recycled. Hot dip galvanizing fits perfectly into a circular economy because it optimises the durability of steel (enabling it to be used again) and facilitates the ease of reuse. It can also be recycled if there’s no immediate need to repurpose it. Read The sustainability of galvanized steel for more detailed information.
D for Design for Galvanizing
When designing steel for construction, also design it for galvanization, as a good design will prevent any processing problems at the galvanizing plant and ensure the best steel coating possible. For design advice, talk to our Technical Team. They’d love to help. You can also download Safe Design for Hot Dip Galvanizing.
E for Environment
At Joseph Ash Galvanizing we are committed to preventing pollution and minimising environmental impacts. For every process of our operations, we take a proactive approach to controlling emissions and ensuring the highest protection for the environment. Follow how we do this in Our Green Future – a fun, interactive graphic showing all our service steps, from collecting steelwork from a customer to its delivery at the end destination and all our environmental processes along the way. See it on our website
F for Fettling
Once steel has been hot dip galvanized, a small amount of surface finishing may be required to smooth, clean or condition the metal. This is known as fettling.
G for Galvanizers Association
The Galvanizers Association provides free authoritative advice on hot dip galvanizing since 1949. Visit their website for a wealth of steel and coatings information.
H for Health and Safety
Health and safety at a galvanizing plant are of the utmost importance. At Joseph Ash Galvanizing, we are committed to ensuring our plants are safe environments to work and visit.
I for ISO Standards
ISO standards dictate ways of doing things, whether making a product or providing a service. They are the distilled wisdom of people with expertise in their subject matter. There are many different standards that Joseph Ash Galvanizing complies with to ensure we provide the best service and product for our customers. Examples are the Coatings Requirements of BS EN ISO 1461:2022, the Quality Management System of ISO 9001, and the Environmental Management System of ISO 14001.
J for Jigging
A jig holds steel in place in the correct orientation throughout the galvanizing process to facilitate ease of handling.
K for Kettle
Galvanizing baths are also known as galvanizing kettles. They are large rectangular structures made from steel plates welded together. They come in many sizes. (We have a range of sizes across the Joseph Ash Group.) Galvanizing kettles are filled with zinc, which becomes a liquid state when heated to 438-460C. Steel that needs to be galvanized is lowered into a kettle at an angle so that the zinc can coat the steel.
L for Lifespan
Steel is a tough, durable metal; it can last for decades when appropriately treated. In the UK, galvanized steel (with a typical thickness of 85 microns) can last about 85 years before it needs maintenance. The lifespan does depend on the environment, however. For example, the lifespan might be slightly less in damp coastal areas or places with high levels of Sulphur Dioxide. For more information, view the Galvanizers Association corrosion map. It’s an excellent resource for calculating the levels of corrosion in atmospheric conditions across the UK.
M for Microns
A micron signifies one thousandth of a milimetre. In the steel and galvanizing industry, in order to be standards compliant, >6mm thick steel requires an average coating of 85 microns. This can last for a century in many UL settings.
As stated by the Galvanizer’s Association: “It is astonishing to think that a coating, just thicker than a sheet of A4 paper, can protect a steel structure for the better part of 100 years.”
N for Nuts and Bolts
At Joseph Ash Galvanizing, we mainly galvanize large items such as lampposts and motorway barriers for our clients. What about the small steel parts that hold the bigger pieces together, though? The nuts and bolts? Yes, we galvanize those in a spin bath at our Telford plant. When nuts and bolts are used to hold parts of a bridge in place, it’s just as vital that they are rust resistant too.
O for Operatives
Hot dip galvanizing is a chemical process, carried out by highly skilled operatives. At Joseph Ash Galvanizing, many of our valued team have been honing their skills over periods of 20, 30 and 40 years, which means your steel is in safe hands.
P for Powder Coating
Powder coating is a paint mainly applied to metals to provide a harder finish than a normal paint. The paint is applied as a powder electrostatically from a spray gun and is cured in an oven under high heat to form a tough, durable skin. Powder coating paints come in many colours and can be used to create different finishes, such as textured or metallic.
Q for Quenching
Quenching is the process where steel is rapidly cooled after it has been lifted from the galvanizing bath by immersion in water and/or a dilute chromate or phosphate solution.
R for Rust
Steel is made from iron, which rusts when exposed to water and oxygen. Rust is the result of a chemical reaction called corrosion. To prevent rust from forming, hot dip galvanizing coats steel in zinc. The zinc reacts with oxygen and carbon dioxide to form zinc carbonate. This becomes a protective barrier, stopping water and oxygen from reaching the steel.
S for Spin Galvanizing
Small items such as nails, chains and screws need to be as rust resistant as the steel structures they support. However, they are too small to galvanize in a hot dip galvanizing bath. With spin galvanizing, small items can be placed in a perforated basket and immersed in molten zinc. Once the zinc/alloy layers form, the basket is centrifuged at high speed so that the spinning action removes the excess zinc and creates a clean profile.
T for Transport
Wherever you are, or wherever the end destination for your fabrications is, Joseph Ash can transport them for you using our large fleet of specially equipped lorries, including articulated, rigid, and Hi-ab craned vehicles.
The ability to collect and deliver steel is vital as we like to make life as easy as possible for customers.
U for Ultrasounds
Galvanizing baths protect steel against rust, enhancing its lifetime. But galvanizing baths need protection, too, so they can continue to galvanize. Non-destructive testing is used for this purpose. The testing involves ultrasounds which determine the thickness of a bath over time. If the bath becomes too thin, it could crack. Not only would this put the bath out of action for many months, but it would also be perilous for our team if molten zinc leaked onto the floor of the plant.
V for Venting
To achieve the best quality zinc coating, it is important to ensure that the molten zinc can flow freely over all surfaces, externally and internally. So, where there are sealed hollow sections or cavities, vent and drain holes are essential. Please download Venting Tips for Hot Dip Galvanizing.
W for Waste
Our galvanizing plants are self-contained – with steel going in at one end and the final product coming out at the other. This means we can control the amount of waste we produce. At Joseph Ash Galvanizing, we minimise waste by recycling it at almost every stage of our operations. For example, Zinc that oxidises on the surface of our baths is removed as ash and recycled, and waste heat is used to warm pre-treatment tanks. Any wastewater generated can also be treated and reused, with only small volumes of stable solids requiring external disposal. See our ‘Green Plan’ for further examples.
X for Xtra Services
At Joseph Ash, we want to make our customers’ lives easier. We do this by providing a range of additional services which include: Collection and delivery, Additional paperwork if requested, bundling, packing and labelling of all steelwork, passivation post-galvanizing, on-site storage, full technical support, a one stop-shop service.
Y for You – Our Customers
At Joseph Ash Galvanizing, the essential part of our process is you – our customers. We hear your requests and treat your steel according to your needs. Whether you need hot dip galvanizing at a certain level of microns, or a duplex coating with a particular colour and finish, we will help. We’ve been in business since 1857 because you have trusted and kept us here.
Z for Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30. It is found in mineral deposits along with other base metals, such as copper and lead.

The galvanizing process coats steel in zinc, which acts as a protective barrier against water, the leading cause of rust. The zinc in a galvanizing bath is molten at 450°C. Once the steel has reached this temperature, it is ready to be lifted from the bath.

How the updated standard affects the galvanizing industry and customers

Hot dip galvanized trailer chassis post-passivation

Some important revisions to ISO 1461 – the British Standard for hot dip galvanized coatings on iron and steel articles – have recently been made. The new 2022 version supersedes the 2009 version.

The standard will be adopted by CEN (the European Standards Organization) and subsequently by National Standards Bodies, including BSI in the UK and the National Standards Authority of Ireland.

Several important changes have been made to the document. As the changes affect both us – as galvanizers – and you – our customers – we’ve listed them below:

Summary of major changes

The most significant changes to the document concern the galvanizing of ultra-low reactive steels, coating thickness measurements on ancillary elements, removal of flux residues and zinc ash, and the renovation of galvanized steelwork.

There has been no fundamental change to the method of assessment of coating thickness, but allowances for measurements on ancillary elements and ultra-low reactive steels have been introduced. The revised standard states that thickness measurements should not be taken on ancillary elements (e.g. brackets) unless specifically requested by the customer. Recognition that certain steel compositions can exhibit ultra-low reactivity during galvanizing (i.e., cannot satisfy the standard minimum coating thickness requirements) has been introduced. Articles produced from steel with a section thickness greater than 3mm which have a composition of ≤0.01 % silicon AND an aluminium content >0.035 %, that exhibit ultra-low reactivity during galvanizing, can now be subject to lower coating thickness requirements (see 6.5 below). The variation to the standard requirements must be included in the Declaration of Compliance if one is to be provided.

An important change has been made with regards to removal of flux residues. In the 2009 version, flux staining/residues were not permitted anywhere on the article, but the updated version now acknowledges that removal (including zinc ash) in some fabrications is practically impossible. Therefore, if ‘access is restricted, for example inside hollow sections’ flux residues and zinc ash are permissible.

The key changes to the content on renovation of galvanized steelwork are the requirement for the pigment in a zinc-rich paint to conform to ISO 3549 ‘Zinc dust pigments for paints — Specifications and test methods’ which has been removed but must still offer sacrificial protection to the steel; and also, more comprehensive information within Annex C – Renovation of uncoated or damaged areas.

Changes in ISO 1461:2022 vs 2009 edition

1 Scope – No significant changes were made to the scope, however clarification to clearly state the standard specifies the general properties of, and test methods for, ‘hot dip galvanized’ coatings were incorporated.

2 Normative references – There has been slight changes to the standards contained within the normative references to reflect their status within the document. Notably, ISO 14713-2 ‘Zinc coatings — Guidelines and recommendations for the protection against corrosion of iron and steel in structures — Part 2: Hot dip galvanizing’ has been included.

3 Terms and definitions – Five new terms, galvanizer (3.3), after-treatment (3.18), additional coating (3.19), wet storage stain (3.20), duplex system (3.21) have been introduced to allow for simplification of the main text.

4 General Requirements – No significant changes.

5 Acceptance inspection and sampling – No significant changes, except the minimum number of articles in a control sample can be subject to deviation following agreement within the supply chain. The new text now reads ‘Unless otherwise agreed, the minimum number of articles from each inspection lot that forms the control sample shall be in accordance with Table 1.

Table detailing the number of articles used as a control sample relative to the total number of articles in a lot

6.1 Galvanized coating properties – Appearance – Clarification has been made that only the visible significant surfaces are subject to the appearance acceptance inspection. Flux residues and zinc ash shall be removed where they can affect the intended use of the HDG article, or its corrosion resistance requirement, unless access is restricted, for example inside hollow sections. Previously, flux residues were not permitted anywhere on the article.

The coating, when first examined by normal vision from a distance of not less than 1m shall be free from blisters (i.e. raised areas without solid metal beneath), roughness and sharp points (if either that roughness or sharp point can cause injury) and uncoated areas. The 2009 version also included ‘Nodules’, however this has now been omitted from the list of prohibited coating features.

6.2 Galvanized coating properties – Thickness – The greater relevance of ISO 2178 ‘Non-magnetic coatings on magnetic substrates — Measurement of coating thickness — Magnetic method’ amongst the other coating thickness measurement standards has now been acknowledged.

6.2.3 – Reference areas – now states that ‘Unless otherwise agreed, reference areas shall not be chosen from ancilliary elements, when they are significantly smaller than the main elements of a larger article’ due to being thinner or less reactive. Acceptance that flame-cutting, laser-cutting and plasma-cutting can lead to the steel being more unreactive during galvanizing and decreased cohesion of the coating has been made. The 2022 edition now reads ‘In order to obtain the required coating thicknesses more reliably and to ensure adequate cohesion or adhesion of the coating, flame-cut, laser-cut and plasma-cut surfaces should have been ground off and sharp edges should have been removed during fabrication and prior to delivery to the galvanizer.

The minimum size of a reference area is now clearly defined as being 10cm2.

6.3 – Galvanized coating properties – Renovation – The circumstances where a lower (than 100μm) minimum repair coating thickness can be agreed, has been expanded to account for thinner galvanized coatings around the damaged area, for example, where aesthetics may be important.

6.4 – Galvanized coating properties – Adhesion – No significant changes, however a new ‘note’ has been added which recognises that cohesion of the galvanized coating can be affected by a steel being ultra-low reactive – as defined in ISO 14713-2 Table 1, Note 4. There is still not a suitable international standard for testing the adhesion of galvanized coatings.

6.5 – Galvanized coating properties – Acceptance Criteria – It is within this section where the adjustment for ultra-low reactive steels has been introduced. The new text reads:  

‘For articles with steel section thicknesses greater than 3 mm, produced from steels with compositions ≤0,01% silicon that also have aluminium contents >0,035%, that exhibit ultra-low reactivity during galvanizing and therefore cannot satisfy the minimum galvanized coating thickness in Table 3, the next lowest category of steel article section thickness given in Column 1 of Table 3 shall be applied. In such cases, if a declaration of compliance must be provided then it shall state this variation including the adjusted minimum mean galvanized coating thickness requirement that has been applied to the inspection lot.

NOTE – Certain steels, including but not limited to, either steels suitable for laser cutting with chemical compositions as given in ISO 14713-2:2019, Table 1, Note 4 or steels with high surface smoothness, or both, can exhibit ultra-low reactivity during galvanizing (see ISO 14713-2) and the coating thickness achieved on such steel articles can possibly not be dependent on steel section thickness. These factors are beyond the control of the galvanizer and can also result in even lower coating thicknesses than given in the next lowest category of steel article section thickness given in Table 3.’

Table detailing the minimum galvanized coating thickness and mass on samples that are not centrifuged

7 – Declaration of Compliance – The terminology has been modified, in ISO 1461:2009 this was referred to as a ‘Certificate of compliance’ whereas now it is called a ‘Declaration of compliance’. Clarification that this must meet the requirements of ISO 10474 ‘Steel and steel products — Inspection documents’ has been incorporated.

Annex A (normative) – Information to be supplied – An important sentence has been added to A.2– Additional information for provision by the purchaser, which states that ‘an indication of any ancillary elements within the article that must be considered as part of the significant surfaces from which reference areas might be taken (e.g. if the ancillary elements are safety critical).’ This is to account for the default procedure of not taking coating thickness measurements on ancillary components.

Annex B (normative) – Safety and process requirements – Venting and Drainage of Articles – Verification has been incorporated into this Annex that states the work presented for galvanizing should be in accordance with ‘either the guidance given in ISO 14713-2 or any further specific guidance for the articles to be processed that may arise from consultations with the galvanizer, or both.

Annex C (informative) – Renovation of uncoated or damaged areas – Annex C contains considerably more guidance on the requirements for a zinc-containing paint used for repair than the previous version (Annex C.1 – Zinc-containing paints). See new guidance below.

‘A dry paint film that is capable of conducting electricity and which is in electrical contact with the basis metal will ensure that sacrificial protection is provided.

Other things being equal, sacrificial protection increases with increases in metallic zinc content in the dried film but does not increase further above approximately 94% by weight of zinc for paints containing zinc dust. However, other factors can be important.

A zinc-containing paint with a zinc dust content that is equal to or greater than 80% by mass in the dry film can be considered suitable for renovation of uncoated or damaged areas. Conformity of the zinc dust pigment, within a zinc-containing paint, with ISO 3549 is a further indication of suitability.

Zinc-containing paints based on lamellar shaped, rather than spherical, zinc particles may achieve adequate protection at lower contents of zinc in the dry film than for zinc dust paints with spherical particles.

Zinc-containing paints may also include an aluminium content for aesthetic purposes.’

Annex D (informative) – Determination of thickness – No significant changes.

Annex E (informative) – Corrosion resistance of galvanized coatings – Annex E has been updated to include supplementary information regarding the long-term, steady-state zinc corrosion rates given in ISO 9224 ‘Corrosion of metals and alloys — Corrosivity of atmospheres — Guiding values for the corrosivity categories.’ This is in appreciation that ISO 14713-1 ‘Zinc coatings — Guidelines and recommendations for the protection against corrosion of iron and steel in structures — Part 1: General principles of design and corrosion resistance’ provides first year exposure corrosion rate data and is therefore conservative guidance.
