Production Intro

             Annual 150000 tons output of hot-dipped galvanized steel in Coils

 

Hengda hot-dipped galvanized steel production line adopts the world's most advanced techniques, which is the United States Steel associated and consisit of widely used surface treatments like surface finishing, straightening, passivation and oiling.  The valiable specifications is 0.2-1.2mm * 800-1250mm with zinc weight  btw 60-275g/m2 (two-sided), presently mainly produce zero spangle. The super quality GI with zero spangle is widely used in home appliances,  industrial instruments, high-end architectural plates and other fields.

 

               Annual 120000 output of color-coated galvanized steel in coils

 

The line adopts advanced three-roll coating, twice-coating and twice baking. The curing system is using advanced indirect heating method to achieve paint cured.The line can produce PPGI steel coils with specifications of 0.15-1.2mm * 800-1250mm. The coating paint can be PE (polyester paint), SMP (silicon modified paint), PVDF (fluorocarbon polyester paint) for choice.  The super quality PPGI can be used both in construction field and home applicances.
