The galvanized coil plate is produced in the continuous hot dip galvanizing production line of cold rolling mill using advanced and improved Senjimir galvanizing method, with excellent quality and stable performance.

The main raw material of iron making is iron ore, the main component of iron ore is Fe2O3, no carbon;

stainless steel containing chromium and nickel metal is more, the appearance of color is much silver bright color. Carbon steel is mainly carbon and iron alloy, other metal elements are relatively small, the main color of the appearance is the color of iron, the color will be much darker.

Stainless steel material has strong thermal sensitivity, and the residence time is slightly longer in the temperature zone of 450-850 ° C, and the corrosion resistance of weld and heat-affected zone is seriously decreased.

Metal materials with metal characteristics formed by alloying process (melting, mechanical alloying, sintering, vapor deposition, etc.) that often contain two or more kinds of metal elements or add other nonmetallic elements on metal base are called alloys.
