Product Description

0.15–3.8mm Z40–Z275 Passivated (Chromated) 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 process.

The passivated (chromated) surface treatment improves resistance to white rust during storage and transportation, making it suitable for roofing sheets and construction applications.

 

2. Technical Solution

 

Performance is based on:

  • Zinc coating (Z40–Z275) providing corrosion protection

  • Chromated passivation layer reducing white rust formation

  • Uniform coating improving durability

  • Metallurgical bonding between zinc and steel

4. Application

  • Roofing sheets and roof components

  • Wall cladding panels

  • Household appliances

  • Automotive parts

  • Industrial cabinets and equipment

 

5. Processing

  • Roll forming for roofing sheets

  • Cutting and slitting

  • Bending and stamping

  • Welding and assembly

 

6. Advantages

  • Effective corrosion protection under normal atmospheric conditions

  • Chromated surface improves storage stability

  • Wide thickness and size range

  • Suitable for forming and fabrication

 

7. How to Choose

  • Roofing application → Z120–Z275 recommended

  • Storage requirement → Chromated surface preferred

  • Painting → Minimized or zero spangle

  • Structural use → Select thickness based on load

 

8. FAQ

 

Q1: What is chromated (passivated) surface treatment?
It is a chemical treatment applied to zinc coating to reduce white rust during storage.

 

Q2: What is Z coating?
Z coating refers to zinc weight per square meter for corrosion protection.

 

Q3: What coating is suitable for roofing?
Z120–Z275 is commonly used depending on environment.

 

Q4: Can it be used for outdoor applications?
Yes, with proper coating selection based on environmental conditions.
