COATING
Different steels specifications for painted and unpainted also available on request. Total coated thickness values are nominal only.
SLOPE
The recommended minumum slope is 3 degree. The amount of water that must be shed increases with the length of the roof. Therefore, to avoid possible back up of water in severe wind conditions, the recommended roof length should be considered as maximum for a given roof slope and rainfall rate.
LENGTHS
G Span profile can be ordered in any length, subject to transport limitations. Longer lengths require special transport arrangements.
