What Is CGI Roofing Sheet?

CGI roofing sheet is short for corrugated galvanized iron roofing sheet, which is a kind of cost-effective building material. With galvanized steel sheet as material, it is profiled into corrugated patterns with a roller mill. The corrugations will increase the strength of the steel sheet. For roofing purposes, the sheets are waterproofing. You can find different designs, including wavy, tile, ribbed, trapezoidal, etc.

How to Estimate the Weight of CGI Roofing Sheet?

Let’s take a 4*12 ft corrugated galvanized steel 29 gauge roof panel for example. The width and length are about 1,219 mm and 3,658 mm. Gauge 29 is about 0.437 mm. It is a very common thickness for roofing sheets. Weight can be calculated by the formula: 7.85*length (m)*width (m)*thickness (mm)+ weight of zinc layer. So it is about 15.3 kg (7.85*3.658*1.219*0.437).
