What is Hot Dipped Galvanising?

Hot Dipped Galvanising is a process used to protect mild steel with a durable zinc coating, providing long-term corrosion protection. Once associated primarily with architecture and

How will Hot Dipped Galvanising change over time?

When Hot Dipped Galvanising is first produced, it has a bright silver appearance. Over time, the zinc naturally oxidises, gradually developing the softer grey patina commonly

How Does Galvanising Influence Design?

Hot Dipped Galvanising should be considered during the design stage rather than selected as a finish once a product has been designed. Unlike many finishes, it influences how components

What are the benefits of Hot Dipped Galvanising?

One of the main reasons Hot Dipped Galvanising is specified is its combination of appearance and long-term performance. It provides a contemporary industrial finish that naturally

Can all metals be Hot Dipped Galvanised?

Hot Dipped Galvanising is a process developed specifically to protect mild steel. Products are fabricated in untreated mild steel before being immersed in molten zinc to create the

Is distortion something to consider with Hot Dipped Galvanising?

Yes. During the galvanising process, mild steel is rapidly heated as it is immersed in molten zinc. As the steel expands and then cools naturally afterwards, some distortion is inevitable.

Why are vent holes required when galvanising steel?

During the galvanising process, fabricated steel is immersed in molten zinc. Any trapped air within hollow sections expands rapidly as the steel is heated, so vent holes are essential to allow

Why doesn't every galvanised finish look the same?

Unlike powder coating, where a specified colour can be reproduced consistently, the appearance of Hot Dipped Galvanising naturally varies in colour, texture and shade.

Is Hot Dipped Galvanising a cost-effective finish?

Hot Dipped Galvanising is a very cost-effective finish, particularly where long-term durability is important. It combines an economical base material with a relatively inexpensive finishing

Can the patination process be accelerated?

Yes. The natural patination process can be accelerated using acid etching, which breaks down the surface of the zinc coating and encourages it to weather much more quickly.

Can Hot Dipped Galvanising be specified for water features?

Yes. Hot Dipped Galvanising is an excellent finish for water features, providing outstanding corrosion protection and long-term durability. In many respects, it is one of the most suitable

Can Hot Dipped Galvanising be Powder Coated?

Yes. Hot Dipped Galvanising can be powder coated, combining the corrosion protection of galvanising with the colour and appearance of a powder-coated finish. Before powder coating,
