Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Weather Resistance: The GI (Galvanized Iron) corrugated zinc roof sheet offers robust corrosion and rust protection through its Z30-Z40 zinc coating, ensuring longevity in harsh outdoor conditions.
  • Structural Support: The corrugated design enhances load-bearing capacity and facilitates efficient water runoff, optimizing durability and safety for roofing applications.

Key features

  • 1. Advanced Material Technology for Corrosion Resistance

    • With a GI (Galvanized Iron) coating (Z30-Z40) and zinc-rich composition, this roofing sheet ensures superior corrosion resistance in harsh outdoor environments compared to uncoated steel sheets. The zinc layer prevents rust and extends lifespan in humid or industrial settings.

  • 2. Structural Strength via Corrugated Design

    • The corrugated profile provides enhanced structural integrity and load-bearing capacity, reducing material weight while maintaining durability. This design outperforms flat sheets in withstanding heavy rainfall, snow, and wind.

  • 3. RoHS-Certified Eco-Friendly Construction

    • With RoHS certification, this product complies with strict environmental and safety standards, eliminating hazardous substances. This makes it ideal for eco-conscious construction projects and regions with stringent regulatory requirements.

  • 4. Versatile Application for Diverse Scenarios

    • Designed for factory, building, and container roofing, this sheet adapts to both residential and commercial needs. Its mid-hardness grade (e.g., DX52D, Q345) balances flexibility and rigidity, ensuring stability in industrial or high-traffic environments.

  • 5. Precision Engineering for Seamless Installation

    • A tolerance of ±10% ensures precise alignment during installation, simplifying integration with diverse architectural designs. This reduces waste and labor costs compared to less standardized materials.

  • Notes:

    • Comparisons: Highlighted competitive advantages over uncoated steel, flat sheets, and plastic roofing.
