ADVANTAGES:A non-puncturing boltless roof, thus reducing potential leaks at fasteners. A concealed fixing system, resulting in a roof with clean lines uninterrupted by protruding screws or bolts and ensuring 100% watertightness. The unique lock and seam fastening process by a robotic seamer holds the roof sheets tightly against uplift or suction forces of strong winds. The profile’s strikingly bold and deep corrugations make it an extremely structurally strong roof requiring fewer purlins, an almost flat roof pitch with a small fascia, all of which contribute to substantial savings in building costs.
