How much does a 26 gauge CGI sheet weigh?
Weight (kg/m 2) 4.322 kg/m 2. For a 26-gauge CGI sheet. Depends on thickness of the zinc coating. For other thicknesses, equivalence is provided in Annex 1 of the CGI sheet roof covering manual. Service life (life expectancy) From 2 years in harsh environments (marine and industrial) to 18 years (rural environment) According to standards:
How can you tell the thickness of a CGI sheet?
The zinc coating thickness can be verified using a coating thickness gauge or magnetometer (EMEAMEASGC01), which measures the thickness of the zinc coating applied to the CGI sheet. Both verifications are crucial to ensure the durability and strength of the CGI sheets. Always use gloves and hard shoes while manipulating CGI sheets.
How many CGI sheets are needed for a roof?
Example: the percentage of overlapping in our case is 13 % as one CGI sheet is enough for the entire roof slope, and the surface of the CGI sheet is 0.92 x 2 m à N = 12.67 / (0.92 x 2.00 x (1 – 0.13)) = 7.9 CGI sheets It is recommended to include a 10% loss to ensure that you will have enough CGI sheets to cover the roof.
What makes a galvanized sheet a CGI sheet?
The gauge conversion depends on the material and its shape. Below is the conversion for galvanized steel sheet (including CGI sheet, ridge cap and fascia cap). Zinc coating thickness and method of galvanization are the most important factors for durability. CGI sheets are protected from corrosion by a zinc coating applied to the steel sheet.
