Our roof structure designs are all designed and engineered in South Africa using heavy-duty Tri-Keder extrusion to suit the spans and girder designs of these unusual roof structures. They can be installed and dismantled quickly and easily using a fork and pin system and are compact enough to be transported inexpensively. Most of our systems have the option of additional Cantilever extensions which can be used to extend the roof of an outdoor stage or to create an open air venue for the corporate market.
