Product Description
1. HOT DIPPED GALVANIZED STEEL DESCRIPTION
Hot dipped galvanized steel is typically a multiple step process that requires a metal workpiece to be fluxed in
molten or aqueous zinc ammonium chloride before a layer of zinc is bonded to it. The pure zinc layer then turns
into zinc oxide when it is exposed to oxygen, and finally zinc carbonate after exposure to carbon dioxide


2. HOT DIPPED GALVANIZED STEEL TECHNICAL PROCESS   
1)After cleaning and acid pickling, the steel coil is submerged in melted zinc, a chemical reaction permanently
bonds the zinc. The zinc actually permanently becomes a part of it and the successive
2)Layers are a mixture of zinc and iron. Hot dipped galvanized steel is a special type of steel coil used
In a number of different applications within fabrication and manufacturing environments

4. HOT DIPPED GALVANIZED STEEL ADVANTAGES
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, no delaminating defects


5. HOT DIPPED GALVANIZED STEEL MAIN USAGE SCOPE
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
