Hangzhou Forsetra Roof Tile Hanger Bars are high-performance structural supports designed for secure and durable roof tile installations. Engineered from high-strength, corrosion-resistant materials, these hanger bars ensure long-term stability and safety for both residential and commercial roofing systems.
To ensure optimal performance, hanger bars must be made from materials that meet structural and environmental demands. Forsetra offers:
Galvanized Steel (G550/AZ150 Coating) - High tensile strength (550 MPa) and superior rust resistance.
Aluminum-Zinc Alloy Coated Steel - Enhanced durability with 120g/m² zinc coating (A120 standard).
Stainless Steel (Optional) - For extreme corrosion resistance (marine or high-humidity environments).
Consult with a structural engineer to confirm load capacity and material suitability for your project.
The hanger bar design must account for:
Roof pitch & truss spacing - Ensures proper weight distribution.
Load requirements - Static (tile weight) and dynamic (wind/snow loads).
Fastener selection - Stainless steel screws (SS304/SS316 recommended) to prevent corrosion.
Forsetra provides custom-designed hanger bars tailored to project specifications, including adjustable lengths and reinforced profiles.
Forsetra hanger bars are manufactured using:
Laser cutting & roll-forming for precise dimensions.
Hot-dip galvanizing for maximum corrosion protection.
Rigorous quality checks (salt spray testing, load validation).
Steel Coil Quality
Verify material grade (G550 for high tensile strength).
Check coating weight (≥120g/m² zinc for standard, AZ150 for aluminum-zinc).
Ensure surface smoothness (no cracks, rust, or impurities).
Supplier Certification
Require mill test certificates (MTC) for chemical composition & mechanical properties.
Laser/Punch Precision Cutting
Tolerance: ±0.5mm in length/width.
Burr-free edges (smooth cuts to prevent coating damage).
Visual Inspection
No deformation, warping, or edge defects.
Dimensional Accuracy
Check profile dimensions (width, height, bend angles) with calipers/jigs.
Ensure uniform thickness (0.7mm-1.2mm, ±0.05mm tolerance).
Coating Integrity
No peeling, cracking, or scratches after forming.
Positioning Accuracy
Hole spacing tolerance: ±1mm.
No metal fatigue or micro-cracks around holes.
Galvanizing/Aluminum-Zinc Coating
Coating thickness test (minimum 120g/m² zinc or AZ150).
Salt Spray Test (1,000+ hours without red rust).
Chromate Passivation (if applied)
Ensures paint adhesion & extra corrosion resistance.
Visual Check
Under bright light at 0.5m distance-no dents, peeling, or discoloration.
Dimensional Verification
Use CMM (Coordinate Measuring Machine) for critical profiles.
Load Testing (Sample Batch)
Static load test (1.5x rated capacity for safety margin).
Fatigue test (simulate wind/snow cycles).
Anti-Corrosion Packaging
VCI (Vapor Corrosion Inhibitor) paper for long-term storage.
Plastic wrapping to prevent moisture ingress.
Handling Protection
Wooden pallets to avoid bending during transit.
Inspection Reports (Dimensional, Coating, Load Test)
Salt Spray Test Certificates (ASTM B117 / ISO 9227)
Material Certifications (ISO 1461, RoHS Compliance)
