Galvacoat®

What is Galvacoat®?

Galvacoat® is a tough, single application polyurethane topcoat that’s specifically formulated to adhere perfectly to Hot Dip Galvanized steel.
Specially designed for Hot Dip Galvanised Steel, it is suitable for all spray systems or brush applications.

Wedge Group Galvanizing Ltd supply Galvacoat® throughout the UK.

Benefits of Galvacoat ®

It adheres firmly to the galvanized surface and does not allow any salts to form, thus maximising the adhesion and delivering a quality coating that can be typically expected to last for up to 15 years.

While most standard paints are intended for use on ferrous metals, Galvacoat® has been designed exclusively for use on non-ferrous metals, and can be applied in a single coating – without the need for special etch primers.


FAQs

Hot dip galvanized steel will last very well in most environments. It is not uncommon for galvanized steel to last more than 70 years under certain conditions. Latest corrosion rates can be found at the Galvanizers Association

The three intermetallic layers that form during the galvanizing process are all harder than the substrate steel and have excellent abrasion resistance.

“White Rust”, or wet storage stain, is formed because zinc on newly-galvanized steel is very reactive and quickly forms zinc oxide and zinc hydroxide corrosion products that go on to become the stable zinc carbonate.
When galvanized steel is stacked damp, stored in wet boxes or shrink wrapped with no free-flowing air, the zinc forms excessive layers of zinc hydroxide, otherwise known as wet storage stain.
Most wet storage stain can be easily removed with a nylon brush. To prevent wet storage stain, store galvanized steel indoors and in such a way to allow free-flowing air between each galvanized item.
