Product Description

0.15–3.8mm G40–G90 (Z100–Z275) Hot Dipped Galvanized Steel Sheet SGCC DX51D for Roofing Applications

 

1. Product Overview

 

Hot dipped galvanized steel sheet is produced by coating cold rolled steel with a zinc layer through a hot dip galvanizing process.

G40–G90 coating corresponds to medium to high zinc layer thickness, providing balanced corrosion resistance and cost efficiency for roofing and general construction applications.

 

2. Technical Solution

 

Performance is based on:

  • Zinc coating range G40–G90 (approx. Z100–Z275)

  • Zinc acting as sacrificial protection layer

  • Uniform coating improving service life

  • Surface treatments reducing oxidation and handling marks

6. Advantages

  • Stable corrosion protection for outdoor use

  • Multiple surface treatment options

  • Good formability and processing performance

  • Suitable for medium corrosion environments

 

7. How to Choose

  • Roofing → G60–G90 recommended

  • Storage → Chromated surface

  • Painting → AFP or minimized spangle

  • General use → G40 economical choice

 

8. FAQ

 

Q1: What is the difference between G and Z coating?
G is ASTM designation, Z is EN/ISO system. They represent zinc coating weight.

 

Q2: What does G40–G90 mean?
It refers to zinc coating range typically used in ASTM A653 standard.

 

Q3: Is anti-fingerprint treatment necessary?
It is recommended for applications requiring clean surface and further painting.

 

Q4: Can this be used for roofing?
Yes, G60–G90 coatings are commonly used for roofing sheets.
