Hocklynn provides a full metal fabrication service for galvanised steel components, producing custom parts, enclosures and assemblies from our factory in Bristol. Galvanised steel is specified wherever corrosion resistance is needed without the cost of stainless steel, making it a practical choice for outdoor equipment, industrial housings and structural applications.
Our galvanised steel fabrication covers the complete manufacturing process: laser cutting, CNC press brake forming, fastener insertion, and finishing. Whether you need a single prototype or repeat production runs, we manage every stage under one roof.
Pre-galvanised sheet arrives from the mill with a zinc coating already applied. This galvanised sheet is ready to cut and form immediately. It is cost-effective and efficient for lighter gauge components where cut edges and weld zones are not exposed to heavy corrosion. The zinc layer is thinner than hot dip, so it suits indoor or sheltered applications. We laser cut and fold pre-galvanised sheet without damaging the existing coating on the flat surfaces.
Galvanising works by covering iron and steel in a layer of zinc. The zinc acts as a sacrificial barrier, corroding preferentially before the base metal. This means that even where the coating is scratched or damaged, the surrounding zinc continues to protect the exposed steel from corrosion.
For parts that need both galvanising and a colour finish, we can arrange duplex coating by powder coating. This combination delivers the longest possible service life and is common on outdoor weatherproof electrical enclosures and infrastructure equipment.
For pre-galvanised sheet metal, we laser cut profiles cleanly without excessive heat damage to the zinc layer. CNC press brake forming follows, with tooling set to prevent marking or flaking on the coated surface.
We handle parts across a range of sizes and thicknesses, from small brackets and panels and enclosure assemblies. Our fibre laser cuts galvanised sheet accurately without excessive heat distortion, and our press brakes form galvanised material with tooling selected to minimise surface marking.
Galvanised steel is specified across a wide range of industrial and commercial applications where long-term corrosion resistance matters. We fabricate galvanized metal components for:
Where parts operate in wet, outdoor or chemically aggressive environments, galvanised steel is the cost-effective alternative to stainless. The initial investment in galvanising pays back through reduced maintenance and longer service life.
Galvanised steel sits between mild steel and stainless steel in terms of both cost and corrosion performance. Choosing the right material for your project depends on the operating environment, the required lifespan and your budget.
If your parts will be used indoors in a dry environment, standard mild steel with powder coating is usually the most economical option. The coating provides adequate protection and the material costs less to fabricate.
If your parts will be exposed to rain, humidity, salt air or chemical exposure, galvanised steel offers decades of maintenance-free performance at a fraction of the cost of stainless.
Stainless steel is the right choice where hygiene, aesthetics or extreme chemical resistance are the primary concerns. For everything else where corrosion protection is needed, galvanised steel is almost always the more practical and cost-effective route.
We regularly advise customers on material selection across all three options. If you are not sure which route suits your application, send us the details and we will recommend the best approach based on your performance requirements and budget.
Galvanised steel is produced by applying a zinc coating to mild steel. Pre-galvanised sheet is coated at the steel mill using a continuous hot dip or electro-galvanising process before being cut to size. Post-fabrication galvanising involves submerging finished steel parts into a bath of molten zinc at around 450°C, creating a durable metallurgical bond between the zinc and the steel.
Galvanised steel is significantly cheaper than stainless steel for most structural and industrial applications. The base material costs less, it fabricates faster, and the galvanising process adds only a fraction of the cost difference. Stainless steel is the better choice where hygiene, appearance or extreme chemical resistance are required, but for general corrosion protection in outdoor and industrial settings, galvanised steel is the more economical option.
“Galvanised” is the British English spelling and “galvanized” is the American English spelling. Both refer to the same process of applying a zinc coating to steel for corrosion protection. In the UK, you will see both spellings used interchangeably.
