Self Supported Roofing Sheets

The sheets are produced and installed at the site without any supports like Trusses, Purlins, or any other structural members. It Provides larger enclosed volumes, free movement, effective handling of goods, and higher utilization. Self-supported roofing sheets have created a revolution in the industry as these roofing sheets do not require any kind of support. Our roofing sheets use mechanical sealing and are installed without any holes, nuts, bolts, overlaps, or sealants thus reducing maintenance cost and maximizing corrosion-resistant property.
