Glavanised sheets
EN 10346 Fields of use
Low carbon steels for cold forming
Typical applications
Extra protection against intensive environmental effects (e.g. air engineering, construction industrial sections and drainage systems).
EN 10346 
Aspects
Adherence of the zinc coating:
It is appreciated after the results of the folding tests on a mandrel. According to the quality grade, on the surfaces of the sheets, there are admitted the following faults, controlled on one surface, visible to the naked eye:
- insignificant increase of the zinc's thickness, with the width of 10mm,on one of the edges
- longitudinal cracks of maximum 3mmfrom the edges
- punctiform low prominence of zinc, distributed uniformly on the surface resulted after the zinc hardening
- different sizes of the zinc flowers
- small defects of chromating
Delivery conditions
Galvanized steel sheets are delivered in bundles of 2.5 tons or in coils of minimum 5 tons.
