Metallic coated steels

Steels with Galfan zinc-aluminium coating

Technical information

Galfan is a flat carbon steel product coated on both sides with a zinc-aluminium alloy. The coating is composed of 95% zinc and 5% aluminium and is applied by means of a continuous hot dip galvanising process.

Galfan is available in a very wide range of steel grades: steels for cold forming and deep drawing applications, structural steels, and high strength low alloy steels.

Galfan metallic coated thicknesses and steel grades meet the EN 10346 – 2015 European standard.

Galfan metallic coated steels are available in the following dimensions:
•    Thicknesses from 0.3 mm to 3 mm
•    Widths from 800 mm to 1525 mm

For structural steel grades, minimum yield strength is between 220 MPa and 550 MPa.

Steels with zinc-aluminium coating

The presence of aluminium in the coating makes the corrosion resistance of Galfan significantly higher than that of standard hot dip galvanised steel of equivalent thickness. Galfan offers excellent edge corrosion resistance.

Thanks to the nature and the particular structure of its coating, Galfan is characterised by very good ductility and excellent forming performance. It is therefore recommended for parts requiring severe deep drawing.

Galfan is used for structural or trim members, metallic ceilings, partitions and partition panels, doors, guttering, metallic door frames, swimming pools, road signs, greenhouses, etc.

Galfan is also an excellent substrate for organic coated steels.
