Audited Supplier It is proceeding by the chemistry degrease and electroanalysis with the cold rolled steel coil and sheet, clean the oils on the surface of steel, sufficiently heated to the proper temperature for zinc coating, pass by level up, strain rectify, and then passivation or annoit etc.
1) Uncoiled and sheared
2) Cleaned using a caustic solution, which can remove oil/grease, dirt, and paint
3) Entry looper to revised and then annealing furnace
4) Steel is dipped into the molten zinc bath
5) Cooled in a quench tank to reduce its temperature
6) Post treatment and crimper
Strict procurement process---skillful technical workers---final products inspection(resistance to corrosion,salt spray test, exposure test, machinability, thermal resistance)---standard packing
1)Low iron loss, high magnetic flux strength, comes up to the international advance standard
2)Slight thickness difference between the horizontal and the longitudinal direction, promising high lamination factor
3)Processing Performance: Easily punched and cut, high dimensional accuracy
4)Insulating coating: Uniform color, good insulation, strong adhesively, high heat resistance, high imputrescibility
5)Smooth surface,no rust,no rolling marks,no cold lap,no crease,no bubble cell
1) Outdoor application:
Roof, structural balcony, panels, window sills, window frames, gates, garage doors, rolling doors, booths, shutters, watc rooms, makeshift houses, street waiting room (booth), refrigerators, etc
2) Indoor application:
Room doors, dividing walls, door frames, light house steel structures, sliding doors, screens, ceilings, toilets, interior elevato lobby, stairwayventilating duct, communication pipelines
