24 gauge astm standard prepainted galvanized steel coil

Hot-Dip Galvanizing or HDG is a process in which zinc bonds to steel at the molecular level to produce a four-layer corrosion-resistant finish. The first three layers are zinc-iron alloy layers that are actually harder than the base steel. The fourth or top layer is pure zinc.

Production process

Galvanized steel coil is used special steel coil as raw material and surfaces (covered with) is painted a layer of organic polymer (or polymer print film),which has advantages of metal material and the organic polymer,24 gauge astm standard prepainted galvanized steel coil not only good adhesive of Organic polymer,formability,corrosion resistance,decorative,but also high strength and easy processing,Galvanized steel coil can be easily punching,bending,deep drawing,welding,etc. So 24 gauge astm standard prepainted galvanized steel coil has perfact practicality, decorative,workability,durability.Currently,the PCM is produced by print film roller coating process and roller painting.
