Galvanized steel flat sheet is cut from galvanized steel coil, the base material is cold rolled steel, it has good processing performance. The zinc layer has uniform thickness, strong adhesion, no peeling during processing, and good corrosion resistance. The surface is smooth and clean, the size is accurate, the board surface is straight, the spangles are even and beautiful.
Galvanised steel sheets are in high demand in industries with stringent requirements for corrosion resistance, durability, strength, appearance and possibility of forming, stamping and applying various additional coatings. The key standards for the production of galvanised sheets include EN 10346 (Europe), ASTM A653/A653M (US).Original manufacturer's standards and regulations should be expressly highlighted.
Classification
The standards applied in different countries to set requirements for galvanised steel specify the range of steel grades and sizes. The key classification criteria of galvanized steel coil sheets include:
Application of galvanised steel (forming, cold forming and manufacture of steel structures)
Chemical composition of coating material (pure zinc or zinc-iron/zinc-aluminium/aluminium-zinc/zinc-magnesium alloys, etc)
Thickness/weight of protective zinc layer
