Metal coated steel

Metal coated steel it’s a cost-efficient method of protecting steel, particularly compared to using stainless steel. It also has environmental benefits since it doesn’t produce emissions and ensures practically maintenance-free use. It’s mostly used unpainted, but if it’s painted the paint coating has good adhesion to the zinc surface.

Because of the sacrificial nature of the zinc, the metal coating provides corrosion protection also for areas of exposed steel surfaces, such as cutting edges and areas where coating has been damaged by scratches or impacts.Full corrosion protection is even achieved in areas that have been heavily formed because there is a low peeling tendency of this low-friction and tightly bonded coating.

Galvanized steel is found everywhere, from nuts and bolts to power line pylons and other large-scale installations. Car bodies are nowadays fully galvanized, making them last longer without rusting. The agriculture industry is an extensive user of galvanized sheet metal and galvanized pipe for cattle gates, fences, wires, and much more.

The building industry uses a lot of galvanized steel for infrastructure such as ventilation, heating, and electrical installations. It’s also used for balconies, staircases, ladders, gutters, rails, tubing, and walkways. The aesthetic appearance is another factor which makes it a favorite material for many architects.

Galfan (ZA) is a zinc-aluminum alloy coating that provides excellent corrosion protection and forming properties compared to traditional zinc coating.

Galfan steel coating features excellent corrosion resistance compared with traditional zinc coating. This is why it can be used to achieve a longer service life for a steel part, or to replace traditional zinc coating with a thinner galfan coating, thereby simultaneously offering improved weldability and formability properties.

A bright metallic and mildly cellular-patterned surface is characteristic for galfan coating. The eutectic composition of 95% Zn and 5% Al improves the coating adhesion and enables a lamellar coating structure in micro-scale. This makes it ductile and well suited for deep drawing.
