• Thickness: 0.20–1.20 mm; Width before corrugation: 914–1250 mm; Effective width after corrugation: 760–1100 mm.

• Coating Types: Polyester (PE), Silicon-Modified Polyester (SMP), Polyvinylidene Fluoride (PVDF), Plastisol.

• Corrugation Profiles: Trapezoidal, sinusoidal, tile-shaped.

• Profile Height: 18–76 mm; Pitch: 76–100 mm.

• Coating Performance:

  • PE: 15–20 years lifespan

  • PVDF: 25–30 years lifespan in outdoor conditions

  • Salt spray resistance: > 1,000 hours for PVDF coating

Applications & Advantages

• Applications:

  • Roofing and siding for industrial warehouses and factories

  • Agricultural building cladding

  • Residential carports, pergolas, and sheds

  • Fencing panels and gate infills

• Advantages:

  • Excellent drainage performance due to corrugation geometry

  • Low maintenance and long service life

  • Variety of colors to match architectural requirements

  • Lightweight for reduced structural load and easier transport

• Example Case: PVDF-coated corrugated boards installed on a coastal warehouse roof showed no significant corrosion after 15 years of exposure to marine atmosphere.

Manufacturing Process & Standards

• Process:

  1. Coil coating of steel sheet with primer and topcoat

  2. Baking and curing

  3. Roll forming into corrugated profiles

  4. Cutting to project-specific lengths

  5. Stacking and packaging

• Standards: EN 10169 (coil-coated steel), GB/T 23988 (color coated corrugated sheet).

• Inspection: Profile dimensional tolerance check, coating thickness measurement (DFT), gloss testing, impact resistance.

• Packaging: Stacked with anti-abrasion interleaves, strapped, and wrapped with waterproof film for shipping.
