The supports have a high load-bearing capacity provided by a system of internal bulkheads welded into position at specific intervals along the length of the rails. Standard construction on the three types offered includes welded 18 Ga. Galvanized steel shell; base plate and counter-flashing; factory-installed wood nailer; fully mitred end sections (two models); and internal bulkhead reinforcement.

The roofing structure is designed to allow penetration of natural, filtered daylight into living areas without the energy loss and higher heating and cooling costs of glass roofing inserts. The company says the pre-assembled system can withstand wind loads of up to 140 mph; has superior UV resistance and impact strength, and exceptional sound-dampening qualities.
