More Informations of our products
 

 
Galvanized sheet or coil is defined as a carbon steel sheet coated with zinc on both sides. Continuous hot dipping, or electro-galvanizing are the two processes used to produce galvanized sheet and coil. Generally speaking, the hot dip process consists of passing the steel through a bath of molten zinc. The electro-galvanizing process consists of the application of zinc by electrolytic disposition. The result is a layer of zinc tightly adhering to the base metal through an iron-zinc bonding layer.
 
A zinc coating is one of the most effective and economical methods of protecting bare steel from a corroding environment. The zinc not only serves as a barrier between the steel and the environment, it will sacrifice itself to protect the underlying steel sheet. Sacrificial, or galvanic protection occurs when two dissimilar metals are in contact and coupled with water and oxygen. Zinc corrodes preferentially to the iron in steel. This protection prevents corrosion of the steel at areas not covered with zinc. Thus, the spread of corrosion from cut edges, drill holes, etc. is minimized.
 
Our Hot-dipped Galvanized products, as well as our Galvannealed (zinc-iron alloy coated) products are manufactured to ASTM A-653 specifications. Our Electrogalvanized products conform to ASTM A-879.
 
Features & Properties:
1. It is decorative, machine-shaping and of high strength and corrosion resistance.
2. It has the quality of both steel and organic polymer;
3. The metal coating and organic coating are combined to protect the steel base, which is stronger
than the pure metal coating;
4. While maintaining the handling characteristics of the basal lamina, the colorful coating promotes
the surface decoration;
5. Made concentratedly in steel factories, it reduces the coating process during the manufacture
of the downstream industry products, which makes the thin coating products of the downstream
industry lower the cost 5%--10%;
