Well done to everyone involved!

Whether you hot dip galvanize steel regularly or are considering it for the first time, choosing the right partner is essential to achieving consistent, high-quality results.

Stuart Cobourne, Group Head of Operations, explains how he and his team work across our nine UK galvanizing plants to help deliver high-quality, sustainable galvanizing.

Can you give us an overview of the department?

My role as Group Head of Operations is to ensure our customers receive products that are not only high quality, but consistently produced, efficient to process, and aligned with modern sustainability expectations. We achieve this by combining strong process control and quality assurance, a clear focus on ESG and our path to net zero, and continuous process improvement to drive operational excellence. This integrated approach allows us to deliver reliable, high-performance products while minimising environmental impact.

We also support our customers beyond general galvanizing services, working collaboratively on product design, material chemistry, and process considerations. 

How does Joseph Ash take pride in the quality of their galvanizing?

We take great pride in the extensive work that myself, the department, and colleagues with a technical aspect to their role have completed to refine the chemistry and metallurgy of our processes and deliver a high standard of coating finish.

The Operations team has recently expanded to include a Chemical Engineer and a Process Engineer, and the business in continually growing and developing to stay ahead in the industry and deliver only the best service for our customers.

Why is quality important when looking for a galvanizer?

Industry standards

BS EN ISO1461 states a certain level of product quality must be achieved for general hot dip batch galvanizing to be supplied to the marketplace. The coating must be continuous, with no bare areas that would corrode if not repaired. It must also be relatively smooth, with no sharp edges or zinc build-up that could cause harm or prevent the article from being installed or used. The coating must also be above the specified minimum mean coating thicknesses detailed within the standard. 

Installation and use

Steel articles that come for galvanizing are products. The design is critical for ensuring these products are suitable to install and use by our customers and end clients. If the galvanizing process is not considered at the design stage, a product could be returned with zinc build-up on critical faces (i.e. plates that are bolted together), meaning the product cannot be installed. Hole tolerances/threaded components also may not be usable after galvanizing. A product may have to be suspended a certain way through the process, leading to holes being required on visible faces which reduces the aesthetic appeal of the product.

How does the quality of the galvanized finish impact the steel’s lifespan?

If the galvanizer is consulted early on in a product’s design phase, the product can be designed suitably based on considerations regarding steel composition and condition. If the galvanizer pays particular attention to their process chemistry and bath metallurgy then hot dip galvanizing can last, maintenance free, for decades. In some cases, it can last for over a century.

Where these considerations are not given – for example, if the galvanizer skips or rushes stages of the process; or doesn’t operate within parameters – there will be areas on uncoated or under-coated steel. These areas will corrode prematurely, resulting in additional maintenance. In worse cases, articles may need to be disassembled to be reprocessed or replaced. This becomes an expensive and time-consuming task for the customer. That’s why it’s important to make sure your galvanizer understands the important of good quality control and is equipped and able to deliver this.

How does Joseph Ash maintain high standards for quality and stay ahead in the industry?

Joseph Ash operate a high level of factory production control. All stages of the chemical pre-treatment are analysed fortnightly – and the bath metallurgy analysed monthly – using chemical titration and optical emission spectrometry. These processes are then adjusted accordingly to remain within optimum parameters at all times. On top of this, the business operates a Quality Management System certified to ISO 9001 to ensure our quality aspects and impacts are assessed and controlled accordingly.

The business is a member of the UK Galvanizers’ Association and I myself sit on the Technical Committee. This allows us to keep abreast of any upcoming industry risks and have input into standards development. We not only have high standards in the Technical arena but also Health & Safety and Environmental considerations. We are certified to both ISO 45001 and ISO 14001 to manage all of our business risk and impacts, both internally to our colleagues and externally to customers, contractors and the local communities we operate in. 

What should customers be aware of when looking to galvanize their steel?

Steel composition

It’s important to ensure that the steel supplied is suitable for galvanizing. When specifying or sourcing steel for fabrications, the steel supplier should be made aware that the steel will be galvanized and supply accordingly. This should be plain carbon, low alloy steels. Where high strength, hardened/cold-worked or high alloy steels are specified, the galvanizer must be consulted at the design stage to ensure any potential concerns can be addressed at the earliest possible stage.

Steel condition

The pre-treatment stage of the galvanizing process involves thorough cleaning of the steel to remove light oils/greases, rust and scale. This allows the characteristic coating growth synonymous with hot dip galvanizing. Whilst robust, this cleaning process cannot remove all potential contaminants that can be present on fabricated steelwork. Paints, wax crayon, labels and weld anti-spatter that is not water-soluble are examples of products that will not be removed by normal processing. Where these products are used, they should be ground off prior to sending material for galvanizing to prevent uncoated areas during the process.

Another common problem can be laser or flame cut edges. The heat-affected zone created by these processes has a dissimilar chemistry to that of the main body of steelwork which can create a very thin (unreactive) coating with poor adhesion. These areas should also be ground prior to sending material for galvanizing. 

Design

The steel’s design should also be considered. This includes:

• Dimensions – Can the material fit in the bath? Will it need to be double-dipped?
• Weight – Is the work too heavy for cranes or FLTs?
• Venting and drainage – Have sufficient venting and drain holes been placed? Can the steel be dipped safely, with all internal areas suitably vented to allow air to escape and process chemicals and zinc to drain?
• How will the work be suspended by the cranes – are there suitable lifting points for the lifting equipment?
• Section size – No part of the fabrication should be more than 2.5x the thickness of any other, as this can cause distortion as the heat transfer of these sections will be different.

We have a venting tips and tricks poster to help our customers with designing their steel for galvanizing.

Any extra advice for anyone who may be reading?

Consult with your galvanizer as early and as often as possible regarding design and specifying products for galvanizing.

Following World Environment Day at the weekend, the Joseph Ash Group has designated the first week of June to be ‘ESG Week’. During this week, we’re raising awareness of the environment and social and governance issues affecting our colleagues, clients, and suppliers.

This is the first year for our new annual event, and so far this week, we’ve delivered presentations on ‘What is ESG?’. We’ve also provided resources (posters and links to activities) to team members to help them understand some of the terminology used (e.g. ‘Carbon Neutral’, ‘Net Zero’, ‘Carbon Offsetting’). Plus, we’ve shared advice on being more energy, waste and water conscious both at work and at home.

Later this week, we’ll be conducting safety tours to reinforce the importance of health and safety in the workplace.

Here are some of the important topics we’re covering:

Environment

• Compliance with all environmental legislation

• Minimise all negative environmental impacts from our operations – emissions to air, water and land

• Minimise our resource usage and support a circular economy

• Reduce our carbon emissions and work towards achieving Net Zero carbon emissions.

Social

• Managing the risks to the health, safety & wellbeing of our colleagues and other stakeholders

• Improve the talent and diversity of our colleagues and create a value-based culture within the business

• Positively engage with our local community by providing support to local initiatives and charities

• Supporting apprenticeships.

Governance

• Effectively identifying, mitigating, and controlling business risk

• Operating in compliance with all applicable legislation

• Ethically conducting business and working with integrity

• Using reputable suppliers and working with customers that support our values

• Ensuring all decision-making is carried out with our values, strategy and impacts considered.

If you want to know more about ESG across the Joseph Ash Group (Joseph Ash Galvanizing and Premier Galvanizing), please get in touch. We’d love to tell you all about it!

When using steel in construction, hot dip galvanizing is an essential part of the project to protect the longevity of the metal. You carefully design your steel to fit the overall build of the construction project, but sufficient care and attention are also required for designing steel for galvanizing. If you design right, you’ll prevent any processing problems at the galvanizing plant and will also ensure you get the best steel coating possible.

When sending steel to a galvanizing plant, you will have several goals in mind:

1. Fast turnaround
2. Premium quality coating
3. Excellent service
4. Good value for money.

Ensuring steelwork is suitably designed for hot dip galvanizing helps achieve these goals and ensures the steel is safe to be galvanized. Poor design can result in poor coating quality, additional costs, low production rates, and failure to meet delivery dates. Poor design can also pose serious health and safety risks for the people carrying out the galvanizing.

What does good design look like?

The importance of venting and drainage

To maintain the safety of our employees and achieve the best quality zinc coating, it is important to ensure that during immersion in the galvanizing bath, superheated air can escape all internal spaces and the molten zinc can flow freely over all surfaces, external and internal. So, where there are sealed hollow sections or cavities, vent and drain holes are essential, otherwise it could result in serious injuries to our personnel.

When steel is immersed in the galvanizing bath, add vent and drain holes to sealed hollow sections or cavities to ensure superheated air can escape all internal spaces and the molten zinc can flow freely over all surfaces, external and internal. Failure to adequately vent would result in trapped air causing an explosion and endangering galvanizing workers. It would also cause zinc build-up where the excess zinc cannot drain properly.

The sizing and location of vent holes are just as important as the provision of these holes. As a guide, make the venting holes as large as the steelwork can manage (but talk to your galvanizer for the best advice for your fabrications). The hole locations will be determined by how the steelwork is hung on the jigs at the galvanizing plant.

When adequately sized and correctly located, vent and drainage holes will:

• Significantly reduce the risk of injury to galvanizers.
• Allow faster immersion and withdrawal speeds which will help to minimise excessive coating build-up and reduce the risk of distortion by minimising temperature differentials.
• Virtually eliminate the risk of damage to product, plant and equipment caused by the explosive vaporisation of entrapped moisture or air.
• Improve the characteristics of the galvanized coating by restricting the effects of zinc solidification during drainage and reducing the mass of zinc required to achieve a good finish.

Overall, a correctly vented product will ensure the safety of our operatives, total corrosion protection, produce an optimum quality finish and reduce costs.

Due to fabrication design and/or processing orientations, the venting requirements for certain fabrications may deviate from the advice provided here. Where required, this will be communicated by your Joseph Ash representative.

Size, weight, and shape matter

A fabrication design should ideally incorporate easily handled components or fabrications which can be single dipped or subsequently assembled by bolting with galvanized fastenings. Double dipping is a possible alternative; seek advice from your galvanizer before proceeding.

Suspension holes or lifting lugs may be needed if there are no suitable points for locating hooks or wires. Once again, lifting points should be positioned to maximise venting and drainage.

Minimising distortion

Fabrications should ideally be symmetrical, suitable for single dipping, and incorporate sections of as near equal thickness as possible at the joints. Components should also fit perfectly to avoid force or restraint during joining. Use continuously welded joints with balanced welding techniques to reduce uneven thermal stresses and the largest possible radii on all curved members.

Venting requirements

Suitably-sized vent holes

The photo shows how large structural hollow section members should have suitably sized vent holes, as well as holes on the opposite side.

Internal venting

Before welding on the SHS leg, create internal flow by venting the main RHS member in appropriate places, as per the photo.

End plate venting

This is how a hollow section end plate should be cropped at all corners prior to attaching to prevent zinc and air traps.

Overlapping surfaces

Leave minimum gap of 2mm between overlapping surfaces. Where seal welding is not practicable stitch welding should be used.

Air lock prevention

The photo shows how stopping short the end plate prevents an air lock.

Zinc free flow

Stopping short cross beams eliminates air locks and allows free flow of zinc through the fabrication.

External venting in hollow section frames

The photo shows a RHS fabrication. The hole size is adequate.

External venting in hollow frames

Note how the holes drilled close to the point of insertion will prevent air locks and zinc traps.

Hole stamping

Holes stamped out prior to weld assembly

At Joseph Ash Galvanizing, we strive to ensure our employees drive safely and efficiently when collecting and delivering projects to our customers. As part of this process, we provide a fleet of modern and reliable trucks and regular driver training.

Our training efforts have recently received a boost at Joseph Ash because Simon Keane – Group H&S Transport Manager – has successfully gained DCPC training centre approval from JAUPT. This allows him to train other drivers and write approved driver safety course materials. In addition, classes will be delivered to other colleagues across our plants, helping them increase their driver safety and vocational training.

Simon’s first course is titled ‘Load Build and Load Restraint Principles’. He also plans to write more classes based around:

• Driver safety
• Customer service
• Health and wellbeing
• Company policies and practices

As Simon has become an approved trainer, it means the following Joseph Ash sites are now classed as Driver CPC Training Centres:

• Bilston
• Telford
• Medway
• Walsall
• Chesterfield
• Hull

Simon aims to deliver training at all sites and invite Joseph Ash/Premier Galvanizing drivers from other sites.

Congratulations to Simon for achieving the approved status for himself and the Joseph Ash Group. This is an excellent job well done and proof that Joseph Ash continually looks after its employees and invests in its people.

Galvanized steel is an integral part of everyday life and is all around us. But how does its prevalence today affect the environment of the future? How sustainable is it? What role does it play in the circular economy? And is the galvanizing process itself environmentally friendly?

Steel is essential for housing, infrastructure, transport, manufacturing, and agriculture. Used as frames for our buildings, safety on our roads, and support for the bridges we cross, we must never waste the resources used to produce it by throwing it away when the original function is no longer valid. Instead, we must repurpose steel, especially if the world wants to move away from traditional business models of use-throw-away-remake to a more environmentally friendly, sustainable circular economy that aims to eliminate waste and repurpose resources.

What is a circular economy, and how can galvanizing play a part?

A circular economy encourages materials to be made, used, reused, 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 be recycled if there’s no immediate need to repurpose it. Here’s how:

Optimising durability

When steel is galvanized, it is immersed in a bath of molten zinc, where it alloys with the iron in the steel to form zinc/iron alloy layers. These layers form the basis of the coating, which is covered with free zinc as the steel lifts from the galvanizing bath. The result is a robust, durable, corrosion-protective finish that will last many years.

Without a galvanized coating, steel corrodes rapidly, leading to a short lifespan. However, with a galvanized coating, steel can last for decades before the base steel is exposed, giving long term protection. This means that steel can be used for the original purpose for which it was fabricated, and – once the project is dismantled – the steel is still good enough to be used elsewhere.

Facilitating ease of reuse

Once a structure – such as a house or fencing – reaches its end of life, the steel can easily be repurposed if it has been hot dip galvanized. The galvanized coating protects the steel from impact and abrasion when disassembled and reassembled.

Recycling

Finally, hot dip galvanized steel fits nicely into a circular economy because it can be melted and used repeatedly without losing quality if there is no immediate need for repurposing.

The zinc coating can also be reused. Zinc and steel are recycled in well-established steel recycling processes. The zinc particulates are returned, without loss of properties, to zinc production plants, where they are incorporated into zinc ingots and reused in the galvanizing process.

How else does the galvanizing process enhance sustainability?

A hot dip galvanized finish gives steel a long life and durability. In addition, it creates a maintenance-free finish, which lessens the carbon emissions usually associated with the upkeep of non-galvanized steel.

Mick Jackson from Joseph Ash Galvanizing says: “Imagine a bridge made from non-galvanized steel. It would need maintenance every year to protect it from rust and corrosion. It would also need repainting at regular intervals. This requires paint, a workforce, transport for the workers and a means to protect the land or water below from paint contamination. This maintenance is not required if the same bridge is made from galvanized steel, therefore carbon emissions are greatly lessened.”

Is the galvanizing process environmentally friendly?

Galvanizing plants are self-contained, with steel going in at one end and the final product coming out at the other.

Modern galvanizing plants also use zinc very efficiently throughout the galvanizing process. For example, excess metal from the dipping process deposits back into the galvanizing bath. Zinc that oxidises on the surface is removed as ash and recycled, and dross from the bottom of the bath is routinely removed and has a high recycling value.

Other process consumables, such as hydrochloric acid and flux solutions, have important recycling or regeneration routes. Spent hydrochloric acid solutions are used to produce iron chloride for treating municipal wastewater, for example. Closed-loop flux recycling is also used in many plants, and improved monitoring and maintenance of flux tanks reduce the volume of solids for disposal. Compared to other coating technologies galvanizing uses low volumes of water, with plants rarely discharging wastewater. Any wastewater generated can be treated and reused, with only small volumes of stable solids requiring external disposal.

While not considered a particularly energy-intensive sector, the galvanizing industry also has set targets for energy efficiency and improved energy management. New technology has seen improvements in burner efficiency, bath lid efficiency, and reuse of waste heat to warm pre-treatment tanks. Plant emissions are also carefully controlled to ensure neighbouring communities are not adversely affected.

A strong commitment to the circular economy

The Managing Director at Joseph Ash Galvanizing, said: “We count ourselves fortunate to be involved with such a sustainable product, playing, as it does, a critical role in extending the life of steel structures by decades. In addition, reducing our environmental impact has been close to our hearts for many years, hence our heavy investment in fume capture and recycling by-products.”

We firmly believe in a circular economy, where the needs of present-day society are met, without compromising the ability of future generations to meet their needs.”

Millions of people every day face the reality of living with a mental health illness – an illness that others may not see, know about or understand. Whether it’s anxiety, stress, depression or low moods, to illnesses such as schizophrenia, bipolar or Alzheimer’s, these conditions can have a dramatic effect on a person’s life.

At Joseph Ash Galvanizing we believe we have a duty of care and a moral obligation to our employees to help them have good mental health, especially as the workplace – regardless of industry or type – can sometimes be a place of additional stress or anxiety.

The Mental Health Foundation says: “We believe in workplaces where everyone can thrive. We also believe in the role of employers, employees and businesses in creating thriving communities.”

We believe in this too, and it’s why we have recently engaged in B.U.D.I.E.S training for good mental health.

The Mental Wellbeing B.U.D.I.E.S. virtual classroom is a one-hour programme to initiate mental health support in the workplace. The virtual classroom course is helping to give our staff the listening skills and B.U.D.I.E.S. framework to support their colleagues throughout the year.

The B.U.D.I.E.S framework focuses on:

B – Build a helping relationship
U – Understand 
D – Determine if your colleague is in crisis
I – Inform about self-help
E – Encourage professional help
S – Safety at all times

The course stresses the importance of listening skills and how to deal with a crisis. It also encourages people to have ‘Wellbeing B.U.D.I.E.S.’ at work – someone to talk to if you’re in need of a friendly ear.

Before COVID, we were due to complete some Mental Health First Aid (MHFA) training courses, but as these were going to be face-to-face, we’re pleased to have found an alternative in the B.U.D.I.E.S. virtual classroom.

A number of our team have already taken the B.U.D.I.E.S. training, and we have two more sessions scheduled for this week.

Later this year, we will complete the MHFA training and we’ll also provide colleagues with full contact details for support including:

• Their local BUDIE (telephone, email, Whatsapp)
• Contact details for our Employee Assistance Programme
• Local support networks

The Mental Health Foundation says: “Mental health is something we all have. When we enjoy good mental health, we have a sense of purpose and direction, the energy to do the things we want to do, and the ability to deal with the challenges that happen in our lives.”

At Joseph Ash Galvanizing we aim to promote good mental health, and foster purpose, direction and the ability to successfully navigate through life.

In the run-up to the COVID-19 lockdown, it was a tricky time for all businesses making decisions about whether or not to keep operating and having to drastically change ways of working. 

At Joseph Ash we made the decision early to maintain operations at all of our Joseph Ash Galvanizing and Premier Galvanizing plants as we have an important role to play in the supply chain of essential service companies – from infrastructure to food manufacturing, security and healthcare.

Some of the things we have been most proud to galvanize in the last month include steel products for the NHS. We’ve been galvanizing clinical waste bins and trucks, crash trolleys, steelwork for the temporary Nightingale Hospitals, and sadly a temporary morgue. 

The above pictures show some of the steel railings we galvanized for the Dragon Heart’s Hospital in Cardiff on behalf of fabricators W Hare Ltd, as well as steel for an emergency extension to an oxygen tank facility at St. Thomas’s Hospital in London on behalf of SWF Ltd. (More photos can be seen in our Photo Gallery.)

Whilst the safety of our team members and customers is always our top priority (see our news story), we’re glad to be continuing with operations, enabling us to support essential services, and hopefully do our bit to keep the economy going.

As health and safety are of paramount importance at Joseph Ash Galvanizing and Premier Galvanizing, we want our plants to be safe for all drivers who drop off and collect loads. With this in mind, we recently produced ‘Safe deliveries’ posters for our customers. 

The poster reminds all drivers who enter/leave our plants to ensure their goods and materials are loaded safely and correctly on their trucks. It has lots of useful tips and advice on how to load and unload correctly. 

The posters are being printed and we aim to post hard copies to customers before Christmas. If you’d like to download an electronic copy so that you can read the safety advice today click here, or call your usual contact number to request a poster.
