SIGMA

DECK roofs are produced in continuous with a metal support in galvanized steel and a waterproofing support in bituminous paper felt on which the various waterproofing sheaths and layers for the protection of the roof can be applied.
The Sigma panel, with its 5 trapezoidal ribs facing downwards, is one of the most popular products for this application, combining functionality, aesthetics, solidity and safety.
