Q345 SS400 Electro Galvanized Steel Coil 0.63mm EGI Coil for Construction and Industrial Equipment
Q345 SS400 Electro Galvanized Steel Coil 0.63mm EGI Coil for Construction and Industrial Equipment
１．Product Overview
Electro Galvanized Steel Coil (EGI) combines the dimensional precision of cold rolled steel with a uniform zinc coating applied through galvanizing processes. The product provides reliable corrosion resistance, excellent surface quality, and good formability for industrial manufacturing and construction applications.
With phosphate surface treatment and a high zinc coating level, this EGI coil is suitable for equipment housings, electrical cabinets, transportation components, building materials, and metal fabrication projects that require both durability and appearance quality.
２．Technical Solution
The steel substrate is coated with zinc to create a protective barrier against corrosion and environmental exposure. The phosphate treatment further enhances surface stability and improves paint adhesion for secondary finishing processes.
The combination of controlled coating thickness, smooth surface quality, and stable mechanical properties allows the material to perform well in stamping, bending, roll forming, welding, and fabrication operations.
