WindLoad Information

windload information

DS-350 doors have State-wide Florida Product Approval for wind load protection up to 150 mph and have been third party tested for uniform static air pressure.

DS-350 roll-up doors are available in round or square profiles. The continuous curtains are made from hot-dipped galvanized steel, and then finished with silicone polyester paint for beauty and durability. Heavy-duty 13 gauge guides attach to 8 gauge wall angles to give maximum wind load protection. Installation to masonry or steel is quick and simple with no special preparation or overhead tracks needed.
