Galvanised: (GV)

Galvanising is a rough grey finish commonly known as Hot Dipped or Hot Spelter Galvanised. The galvanising process creates a protective zinc layer, offering exceptional corrosion resistance and longevity. Perry galvanising is industry leading with up to 60% thicker microns to other leading brands, making it the superior finish on the UK market, now all Perry fully Galvanised products come with 25 year guarantee.

Corrosion Resistance: 4 - Excellent corrosion resistance, making it ideal for rugged outdoor conditions.

Self Colour: (SC)

Self Colour means the product is uncoated and has a natural, raw appearance. This finish is often used to paint over the product.

Corrosion Resistance: 1 - No corrosion resistance; best suited for dry indoor environments.

2

Zinc Plated: (ZP)

Zinc Plated hardware is versatile and suitable for a wide range of applications as it provides a moderate protective layer against corrosion, enhancing the longevity of the item.

Corrosion Resistance: 2 - Moderate corrosion resistance; suitable for general use, but not ideal for harsh outdoor conditions.

5

Stainless Steel: (SS)

Stainless Steel is a premium material with an attractive silver finish, suitable for a wide variety of outdoor applications, where extreme weather resistance is needed.

Corrosion Resistance: 5 - Excellent corrosion resistance, suitable for all environments, including marine and corrosive settings.
