Galvanized steel taken through an annealing furnace so the zinc and iron alloy together, leaving a matte satin surface that takes paint directly.
About the material
Galvannealed steel starts as hot-dip galvanized and is then passed through an annealing furnace. The heat drives iron from the substrate up into the zinc, so the coating becomes a zinc-iron alloy through its full thickness rather than a layer of zinc sitting on steel.
The surface that results is matte and slightly rough — the satin coat the trade names it after — and it accepts paint directly, without the pretreatment a bright galvanized surface needs.
The alloy coating is harder and less ductile than zinc, so it can powder or flake under severe forming; forming behaviour should be proven on the material being used.
It is the usual choice where a painted finish has to hold on a coated substrate.
Grades, finishes, and availability may vary by branch. Please contact your local branch for current product availability.
