Our product portfolio covers products like automatic garage doors, sectional doors, paneled roller shutters, insulated lath roller shutter, insulated glazed sectional doors and folding steel door. Our roller doors are made of press formed profile panels of hot dipped galvanized or plastisol coated steel and lock seamed to form a rigid continuous curtain of steel. We use galvanized guides complete with nylofelt on all doors and additional stainless steel band on the larger doors on which they eliminate the need for greasing which saves on maintenance and is essential in applications such as the food industry. As in the process we fit weather-seal to the bottom rail on all doors. It helps by providing a seal to reduce ingress of foreign elements.
