Door panels manufactured from galvanized steel sheets, bonded together with high density CFC free polyurethane foam, providing a U-value of 0.44 W/m²K with a thermal break between panels. Vertical and horizontal tracks, hinges, brackets, cappings and hardware are galvanized, with the assembled door running on adjustable galvanized roller carriers bolted to each individual panel.

The door is counterbalanced by tempered helical springs at high level, mounted on steel plates with self aligning roller bearings giving a smooth, quiet operation. Rubber seals are fitted to the top and bottom of each door and PVC seals to each side of the opening to give protection against weather. Cable tensioning devices are fitted as standard and a range of operation, track and finish options are available.
