Product Description

Q235 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 or shearing processing and is widely used in structural fabrication, sheet metal processing, and general industrial applications.

Typical issues include:

Corrosion in humid or outdoor environments
Surface condition affecting painting or forming
Flatness and dimensional stability influencing fabrication

2. Technical Solution

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

Key characteristics:

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

8. FAQ

Q1: What is 323.9mm?
It is not a valid specification for galvanized steel sheet and should not be used.

Q2: Why is Coil ID removed?
Because this page is for sheet, not coil. Coil ID is not a finished sheet parameter.

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