Product Description

Q345 Hot Dipped Galvanized Steel Sheet 40–275 g/m² for Structural Fabrication and Industrial Applications

1. Product Overview

Hot dipped galvanized steel sheet is produced from galvanized steel coil through cut-to-length processing and is widely used in structural fabrication, sheet metal processing, and general industrial applications.

Typical issues include corrosion in outdoor environments, surface condition affecting finishing processes, and dimensional consistency affecting fabrication.

2. Technical Solution

The zinc coating is formed through hot-dip galvanizing, providing barrier protection and sacrificial corrosion protection.

Key features:

Zinc coating: 40–450 g/m²
Basic corrosion resistance
Multiple surface options
Optional surface treatments

8. FAQ

Q1: Why is Coil ID removed?
Because this page is for sheet, not coil.

Q2: What is 323.9?
It is not a valid parameter for galvanized steel sheet and should be removed.

Q3: Why is YX75-200-600 removed?
Because it is a roofing sheet profile, not a flat sheet specification.
