RIBTYPE & CORRUGATED ROOFING SYSTEM – FULL PRODUCT DESCRIPTION
Ribtype and Corrugated Roofing System is a durable, lightweight, and cost-efficient metal roofing solution designed for residential, commercial, and industrial applications. It is manufactured from high-quality pre-painted galvanized steel sheets with protective zinc coating to minimize premature rusting and ensure long-term corrosion resistance, especially in tropical and coastal environments.
The roofing sheets have an effective width of 1.07 meters and are factory-coated with a 15–20 microns top coat paint, 5–8 microns primer coat, and 8 microns back coat, providing superior protection against UV exposure, oxidation, and environmental deterioration. The ribbed and corrugated profiles enhance structural rigidity, improve water runoff efficiency, and ensure leak-resistant performance.
Available thickness options include 0.35mm, 0.40mm Commercial, 0.40mm Standard, 0.50mm, and 0.60mm, allowing flexibility depending on structural requirements and project specifications.
This roofing system is installed using appropriate fasteners, sealants, and accessories to ensure proper alignment, secure anchorage, and watertight installation. It offers excellent durability, low maintenance, and a service life of 15–25 years under normal environmental conditions.
Suitable for residential houses, warehouses, commercial buildings, industrial facilities, and various roofing applications requiring reliable and economical roofing protection.
TYPES:
5 ribs, 6 ribs, Eight ribs, Twin ribs, 4 rib, High rib, Corrugated, Curved Ribtype
