Huada galvanized is produced on continuous hot dip galvanizing lines by passing prepared coils through a bath of molten zinc.The zinc coatings on these products help resist corrosion due to the barrier protection and sacrificial characteristics of the coating. The required zinc coating thickness for different coating specifications is achieved as the result of passing the hot dipped strip through a variable low pressure, high volume air stream, called an "air knife."
The zinc layer on the surface of the galvanized steel sheet isolates the steel sheet from atmosphere to prevent further corrosion of the base sheet and ensures a long service life of the base sheet, due to the excellent corrosion resistance of the galvanized steel sheets. Besides, our galvanized steel sheets are economic and functionally diverse, meeting the requirements of different environments and applications and provide high added value for various combination of products. Now, the galvanized steel sheets are in common use in many fields such as precision instruments, computers, electronic appliances, architectures, color coating, etc.

Surface Treatment:
Chromating treatment or anti-finger print
Surface Finished:
REGULAR SPANGLE:
Regular spangle is also called normal spangle which is naturally formed without any additional treatment during galvanizing.
MINI SPANGLE:
The spangle is restrained and formed as mini spangle by reducing the lead content in the zinc liquid or by blowing the zinc powder from the equipment installed on the zinc pot.
EXTRA SMOOTH:
The mini spangle is further skin-passed to produce the extra smooth surface.
