Galvanized steel coils are steel coils that have been coated with a layer of zinc to protect the steel from corrosion This process is known as galvanization These coils are widely used in various industries including construction automotive and manufacturing due to their durability resistance to rust and versatility The zinc coating provides a protective barrier that helps prevent corrosion and increases the lifespan of the steel
HS Code

65Mn CK67 high carbon cold rolled spring steel strip
Hardened and Tempered Steel Strip
Hardened and Tempered is a thermal process that strengthens steel strips through a controlled heating and cooling process. The hardening process involves heating the steel strip to above the rapidly cooling. The steel strip in this condition is extremely brittle and requires further treatment in the tempering. Then strips are reheated to a lower temperature and holding it at the given temperature for a given period of time. This process is done in an inert atmosphere to avoid oxidation. This type of steel strip has big degree of toughness and has excellent spring properties
