EN 10346 Grade HX220YD zinc-aluminium coated (+ZA)
EN 10346 Grade HX220YD zinc-aluminium coated (+ZA) introduction
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.
Because of 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.
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 improved edge corrosion resistance.
