A Guide To Ironmongery Finishes
Galvanisation is the process of applying a coating of zinc to steel, this gives the ironwork a thick (approx 60 microns), rough coating but adds long term resistance to corrosion.
All the ironmongery within our shop referred to as Galvanised is hot dip/hot spelter galvanised, this ensures that all parts of the metalwork are coated with the molten zinc.
E-Galvanised/BZP (Bright Zinc Plated/ Zinc Plated) Ironmongery
E-Galvanised is the process of electroplating zinc onto steel, this makes for a nicer looking piece of ironmongery than hot dip galvanised – however the coating is a lot thinner (6-8 microns) meaning that E-Galv/BZP is not as corrosion resistant.
Power coated steel. The polyester powder coating is baked or sprayed onto the metal.
If the ironwork is a part that takes wear or is a moving part, then the coating can chip or flake and the exposed steel can then be subject to corrosion.
Black on galvanised
Like the E-Black, the premium black is polyester powder coated. Unlike the E-Black, the Premium black is hot dip galvanised prior to being powder coated.
This gives a more durable finish against corrosion and is recommended over the standard black ironmongery.
Stainless Steel Ironmongery
Grade 316 marine grade stainless steel, also known as A4 Stainless steel. Used in coastal locations where the steel’s ability to resist corrosion is a must and in high performance situations.
Recommended for use on both Oak and Accoya where the acids present within the timbers can otherwise react with non-stainless steel ironmongery (usually turning the timber a blue colour and corroding the ironmongery).
