1. Product Overview

Hot dipped galvanized steel coil is supplied as a zinc-coated base material for sheet processing, roll forming, and structural fabrication. The zinc layer formed during continuous hot-dip galvanizing helps improve corrosion resistance in storage, transport, and service environments.

The thickness range of 0.09–3.8 mm allows the coil to cover both light-gauge applications and medium-duty fabrication requirements. Standard coil IDs of 508 mm and 610 mm are compatible with common industrial decoiling and slitting equipment, which helps simplify downstream production.

2. Technical Solution

Product performance is based on the following technical characteristics:

• Continuous hot-dip galvanizing with controlled coating weight
• Zinc layer providing barrier protection and sacrificial protection
• Balanced strength and elongation for forming and structural use
• Standard coil dimensions for processing line compatibility

Yield strength of 195–420 MPa supports dimensional stability and load-bearing use, while tensile strength of 270–500 MPa improves resistance to deformation during fabrication. Elongation of 12–25% helps the material adapt to bending, stamping, and profiling operations.
