Self Supported Roofing Sheet

The sheets are produced and installed at 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 uses mechanical sealing and installed without any holes, nuts, bolts, overlaps or sealants thus reducing on maintenance cost and maximizing on corrosion resistant property. With no need of making holes, drilling nuts and bolts, the overall time for installation lowers down remarkably thus increasing the efficiency with faster project turnaround.
