Ideal for projects prioritizing cheap metal roof sheets affordability without compromising quality, our products are backed by 15+ years of manufacturing expertise and global certifications.

Specifications

Key Attributes

1. Industrial-Grade Durability:

   • Triple-layer protection: galvanized base (60–275 g/m² zinc coating), epoxy primer, and UV-resistant PVDF topcoat ensure 30+ years of service in coastal or high-humidity zones.
   • Compatible with aluminium alloy roofing sheets for hybrid architectural designs.

2. Structural Excellence:

   • Tensile Strength: Grades TS230–TS620 support seismic loads (up to 2.0 kN/m²) and heavy machinery installations.
   • Bending Strength: Trapezoidal rib design reduces deflection by 35%, achieving a safety factor 3x higher than standard materials.

3. Cost-Effective Solutions:

   • Lightweight (3–10 kg/m²) reduces structural reinforcement costs by 30%.
   • Competitive cheap metal roof sheets pricing starts at $4.5/sq.ft for bulk orders.

Technical Insights

Tensile & Bending Strength

Our allied roofing and sheet metal products undergo ASTM/JIS-certified testing to ensure compliance with global standards. The cold-rolled steel microstructure guarantees uniform tensile strength, while trapezoidal ribs distribute stress evenly to prevent localized buckling. For high-load environments, TS620-grade sheets provide a safety factor of 3.5x against dynamic forces.

Weight Calculation

Calculate sheet weight using:
$\text{Weight (kg)}=\text{Length (m)}\times \text{Width (m)}\times \text{Thickness (mm)}\times 7.85(\text{steel density})$
Example: A 10m × 1.2m sheet at 0.5mm thickness weighs $10\times 1.2\times 0.5\times 7.85=47.1\text{kg}$.

Identification & Traceability

Each sheet is laser-etched with:

• Grade (e.g., TS275, AZ150)
• Coating type (Galvanized/Aluzinc/PVDF)
• Batch number for ISO 9001 compliance.

Why Stainless Steel Can Rust?

While stainless steel resists corrosion, specific conditions trigger oxidation:

1. Electrochemical Corrosion: Chloride ions (e.g., seawater, road salt) penetrate the chromium oxide layer, forming micro-galvanic cells that erode the protective film.
2. Mechanical Damage: Scratches or welding defects expose the iron-rich substrate to moisture, leading to localized rust.
3. High-Temperature Degradation: Prolonged exposure above 400°C weakens the oxide layer, accelerating oxidation.
4. Sulfide Contamination: Impurities like sulfur during manufacturing create "pit initiation points" by leaching chromium from surrounding areas.

Preventive Measures:

• Use thicker zinc coatings (≥180 g/m²) for corrosive environments.
• Avoid abrasive cleaners; opt for pH-neutral solutions.

Why Choose Our Stainless Steel Roofing?

1. Certified Material Quality:

   • 18% chromium + 8–10% nickel alloy exceeds ASTM A240 standards, ensuring 50+ years of service.
   • Precision cold-rolling guarantees ±0.02mm thickness uniformity.

2. Global Compliance:

   • ISO 9001, RoHS, and LEED certifications align with allied roofing and sheet metal sustainability goals.
   • Fireproof Class A rating (EN 13501-1) for wildfire-prone regions.

3. Custom Solutions:

   • OEM/ODM services for embossed patterns, perforations, and hybrid designs with aluminium alloy roofing sheets.
   • 15-day lead time with MSC-certified logistics.

4. Cost Efficiency:

   • Cheap metal roof sheets pricing without compromising on SGCC/HRB80 certification.
   • Lightweight design reduces installation costs by 25%.

Why Our Stainless Steel Stands Out

• 15+ Years of Expertise: Backed by a proven track record in galvanized steel production.
• End-to-End Quality Control: IQC, IPQC, and FQC protocols ensure defect-free deliveries.
• Sustainable Manufacturing: 100% recyclable materials reduce carbon footprint.
• Global Trust: Trusted by infrastructure projects across 50+ countries.
