Product Description

40–450g/m² Zinc Coated Hot Dipped Galvanized Steel Coil 0.09–3.8mm for Manufacturing

1. Product Overview

Hot dipped galvanized steel coil is produced by immersing cold rolled steel into molten zinc, forming a metallurgical bonded coating layer. This coating improves corrosion resistance and ensures stable performance in both indoor and outdoor environments.

The coating range of 40–450 g/m² allows the material to cover general, structural, and high-corrosion applications.

2. Technical Solution

Performance is based on:

Zinc coating providing sacrificial corrosion protection
Uniform coating distribution ensuring consistent durability
Cold rolled base material offering stable mechanical properties

7. How to Choose

General indoor use → 40–120 g/m²
Outdoor construction → 120–275 g/m²
High corrosion environment → 275–450 g/m²
Forming or painting → Anti-fingerprint surface

8. FAQ

Q1: Why not use Z60–Z275 anymore?
This specification is replaced by unified coating range 40–450 g/m² for consistency.

Q2: Can coils be converted into sheets?
Yes, galvanized sheets are produced by cut-to-length processing.

Q3: What determines coating selection?
Environmental exposure level and required service life.

Q4: Is this suitable for structural use?
Yes, depending on grade selection and thickness.
