Galvanneal Steel? Galvanneal Steel is a continuously hot dipped
galvanized product with the zinc coating completely converted to a
zinc-iron alloy. It is this Galvanneal coating that provides corrosion
resistance similar to what you see in the automotive industry. All
Vision Hollow Metal steel doors and frames are manufactured using
Galvanneal Steel as standard.
Why use Galvanneal Steel instead of cold rolled steel?
Galvanneal Steel compared to cold rolled steel is a far superior
zinc-iron coated product. In manufacturing of steel doors and frames
there are two distinct advantages for using Galvanneal Steel.
Superior Corrosion Performance:
Galvanneal Steel has improved coating control over the entire product,
thus the coating composition is consistent and uniform in appearance.
The very fine matte finish acts like a primer and is naturally an
excellent shield against rust.
Paintability and Long Reliable Service Life:
A tightly adherent paint film on Galvanneal Steel lasts longer then it
would on non-galvanized steel because the zinc helps prevent rusting and
blistering. Paint and zinc together will help to extend the rust free
life of the product as compared to unpainted galvanized steel or painted
non-galvanized steel products.
