GALVANISED STEEL – GL
Hot dipped galvanised steel has a protective zinc coating to prevent the steel from rusting by forming a coating of corrosion-resistant zinc which stops corrosive substances from penetrating through to the more delicate steel beneath. As a minimum standard all our steel products have 75µm galvanised finished to BS EN ISO 1461. To review corrosion rates for your project area visit the Galvanisers Association.
POWDER COATED – GPC
Once the steel has been galvanised it can be left with this durable finish, but it can also be powder coated to match a project’s specific colour scheme. Most of the steel frameworks and products we provide can be powder coated to any colour, for example to a supplied RAL reference.
STAINLESS STEEL – SS
Stainless steel is not prone to rust, corrode or stain as mild steel does. We provide two different grades of stainless steel (to be advised upon quotation request) to suit the environment the steel is exposed to. Marine grade 316 (SS-316) has added molybdenum (2%) to help resist corrosion to chlorides (like sea water and de-icing salts). Whereas the standard 304 (SS-304) contains 18% chromium and 8% nickel.
