Corrugated galvanized roofing sheets offer good strength-to-weight performance and drainage efficiency. The corrugated profile helps improve structural stiffness and allows quick installation with standard fasteners. The zinc coating provides barrier and sacrificial protection for outdoor roofing and cladding applications. Specific performance data is available on request.
Agricultural structures: livestock barns, poultry sheds, grain storage facilities, equipment shelters, and farm outbuildings
Residential and commercial roofing: home roofs, veranda awnings, fencing, wall cladding, and carports
Industrial and warehousing: workshop roofing, warehouse siding, temporary site enclosures, and storage sheds
Disaster relief and modular housing: emergency shelters, temporary worker barracks, and prefabricated housing units
General roofing, cladding, and fencing
Every batch undergoes inspection, including zinc coating thickness measurement, bend tests, tensile strength verification, and surface checks. Salt spray corrosion testing is available on request. A Mill Test Certificate (MTC) can be supplied on request, and third-party inspection is available on request.
To reduce moisture penetration, white rust, and edge deformation during long-distance transit, our roofing panels use multi-layer export packaging: rust-inhibiting VCI paper, waterproof plastic film, metallic corner protectors, and high-tensile steel banding on heat-treated wooden skids. This packaging is suitable for container shipment and safe unloading.
