1. Due to the excellent weather resistance of the galvanized layer , theservice life is very long and

does notrequire any maintenance costs . Compared with processes such as paint -ing , painting , 

etc , maintenance isrequired

2. It has good hardness and mechanicaproperties, and can withstand mechanical damage during 

handling,hoisting, etc.

3. Due to the chemical activity of zinc isstronger than that of steel , even ifhere are small defects on 

the surfaceof the zinc coating , it can protect thesteel substrate exposed on the sur -face after the 

zinc coating is missing

4. The hot-dip galvanizing process doesnot affect the mechanical propertiesof the original workpiece 

structural designIt has good hardness and mechanicaproperties, and can withstand mechanical 

damage during handling,hoisting, etc.

• Surface condition

Due to the different treatment methods in the coating process, the surface condition of the galvanized 

sheet is also different, such as ordinary spangle, fine spangle, flat spangle, no spangle and phosphating 

surface.

• Packaging
  

Water proof paper is inner packing,galvanized steel or coated steel sheet is outer packing , side guard plate,

then wrapped by seven steel belt.or according to customer's requirement
