DC01 Galvanized Cold Rolled Steel Coil are used for?
DC01 Galvanized Cold Rolled Steel Coil is cold rolled and galvanized (usually electro-galvanized) to provide good formability, surface quality and rust resistance
Used for
Home appliance manufacturing: used for the outer shell and internal structural parts of refrigerators, washing machines, air conditioners, etc., taking into account both rust prevention and aesthetic needs.
Automotive parts: making door inner panels, fuel tanks, instrument panel brackets, etc., suitable for stamping and welding processing.
Electronic chassis: server housings, distribution boxes, etc., providing electromagnetic shielding and mild corrosion protection.
Architectural decoration: light building materials in dry environments such as indoor ceiling keels and partition boards.
Hardware: low-cost rust-proof parts such as hinges and brackets.
