Hot dip (or hot) galvanizing is the technology to dip the pretreated original plate of carbon steel into meltedliquefied zinc to obtain a protective zinc coating.

For good anticorrosion performance, galvanized steel sheet is vastly applied into the industries of home appliance, decoration,advertisement, and civil construction, etc. Particularly, the home applianceindustry (outer shell of air conditioner, outer plate of refrigerator, outershell of washing machine, computer, and microwave oven, etc) and color coatedplate has large demands on galvanized plate.

Hot dip aluminum zinc silicon steel plate – Galvalume(Referred to GL steel plate), is steel plate to hot-dip coat aluminum (Al 55%),zinc (Zn 43.5%), silicon (Si 1.5%) alloy on the surface of the steel plate. Itis a steel matrix composite, has excellent corrosion resistance. Hot aluminumzinc alloy steel plate performs outstanding in atmospheric corrosion resistance,thermal oxidation resistance of the aluminized steel plate and electrochemicalprotection of the galvanized steel plate.
