Cold rolled steel sheets and strips, electrogalvanised

 

Drawn steels DC01 – DC05 + ZE25/25, ZE50/50, ZE75/75

Produced by cold rolling process at ambient temperature which is followed by hot dip galvanising in Zinc bath.We supply them in sheets from 0,6 to 3,0 mm thicknesses, when we can split them longitudinally or transversally, in various dimensions.

 

Standards:

 

Technical terms of deliveries

EN 10152

Dimensional and shape deviation tolerances

EN 10131

Application: Thanks to its corrosion resistance, these multi-purpose materials are used especially for the manufacture of machinery parts, industrial equipments, cars bodywork, roof covering, household appliances, e.g. washing machines, fridges etc. They have good formability and high strength. Because of to very thin Zinc layer thickness, the surface of those part sis treated additionally by varnishing. The electrolytically zinc-coated steel provides a high chemical purity of te coating layer and even, controllable coat thickness (deviation +/-0,1 µm).
