Trapezoidal PVC‑steel roofing tile, Wadesiju APVC‑A series

Deshiju APVC‑A Series: This product is primarily formulated with polyvinyl chloride resin (PVC), reinforced with red clay, and incorporates UV stabilizers and antioxidants. Its surface layer is developed using a proprietary formulation, meticulously blended according to scientific proportions and manufactured through advanced processing technologies. These measures significantly enhance the product’s oxygen index, surface hardness, mechanical strength, and resistance to acid and alkali corrosion, while also slowing down aging and color fading.

Installation Technical Guide

1. For roofs installing our products, a slope of approximately 20% is recommended; when the building span exceeds 30 meters, the slope should be around 25%.

2. For the steel structural materials used in installing our products, it is recommended to select materials that comply with national standards; their specifications and grades must meet the required load-bearing capacity, and consistency must be ensured.

3. The ultraviolet radiation in the installation area shall not exceed 50 mW/m², and the ambient temperature shall be ≤ 50°C.

4. Do not place this product directly over other products with different waveforms or wavelengths, nor apply it directly to metal‑covered surfaces, to prevent the metal from absorbing heat and causing deformation of the PVC material.

5. PVC material exhibits thermal expansion and contraction; therefore, the length of each individual component should not exceed 10 meters to prevent excessive dimensional changes that could loosen fastening screws or crack the mounting holes.

6. Purlin spacing must be uniform, with a maximum spacing of 800 mm (within the standard wave‑form spacing requirements).

7. During installation, personnel must not step on the product while standing over an open space to prevent safety accidents or product damage.

8. Please pre-drill holes using a hand‑held drill; use a drill bit specifically designed for plastic, with a diameter 2–4 mm larger than the mounting hole’s nominal size to allow for thermal expansion and contraction. Ensure the edges of the drilled holes are smooth, avoid applying excessive force, and exercise extra caution when drilling in cold weather. Place a suitable support beneath the product during drilling.

9. All fasteners shall be installed at the ridge, ensuring they are perpendicular to the roofing surface. Do not overtighten the fasteners, as this may cause deformation of the roofing tiles and lead to leaks.

10. The number of fasteners shall be no fewer than four per square meter, and a waterproof flashing may be installed above the fasteners. For sections laid along the perimeter of the rafter system, appropriately increase both the number of fasteners and wind‑pressure‑resistant plates, ensuring that the length of the corrosion‑resistant tiles extending beyond the eave purlins does not exceed 100 mm. Additionally, use strip‑shaped stainless steel to securely clamp and fasten the entire rafter perimeter, preventing the edges from being lifted by strong winds.

11. Horizontal overlaps of roofing panels must be aligned with the prevailing wind and rain direction: resin tiles, trapezoidal tiles, high‑profile tiles, and large‑round‑wave tiles shall overlap by one wave; low‑profile tiles shall overlap by two waves. When the building span exceeds 24 meters, three wave overlaps are required.

12. The longitudinal lap length shall be 200 mm, with the purlin positioned at the midpoint of the lap joint; an additional two fixing screws shall be installed at the lap joint.
