Galvanized steel strip

1.Galvanized steel strip

Galvanized steel strip is cold or hot-rolled,long and narrow strip of different degrees of plating a layer called the (zinc) of raw materials. Hot dip galvanized has the advantages of uniform coating,strong adhesion,long life and so on.Hot-dip galvanized steel pipe matrix and the plating bath make series of complex physical and chemical reactions,then form corrosion-resistant structure of a close zinc-iron alloy layer. Alloy layer, pure zinc layer and strip matrix come into integration.So it has strong corrosion resistance.

Processing technique

  On the first stage,the entire should be conducted acid cleaning till the surface gets smooth.

  On the second stage,after acid cleaning,the steel should be washed with ammonium chloride or zinc chloride liquid or mixture liquid of ammonium chloride and zinc chloride, and then put it into hot-dip galvanizing bath for zinc plating.

On the third stage,rolling the galvanized steel and store them in the warehouse,what’s more,normally the galvanized layer should be more than just 500g/,among them,each sample must be more than just 480/according to the requests of the customers.
