Rolling Steel

DAB Series 1200 rolling steel doors are assembled using individual interlocking slats (flat or curved) to form a continuous steel curtain the height of the entire door opening. Series 1200 steel curtain doors are manufactured from 22-gauge G90 steel that has gone through the hot-dipped galvanizing process for superior corrosion resistance. The series 1200 steel curtain doors can be upgraded to a 20-gauge or 18-gauge G90 steel to meet higher performance requirements. The individual slats are high-tech riveted with wind locks for smooth and trouble-free operation. A steel bottom bar is a standard feature on the series 1200, incorporating a flexible weather seal for additional weather protection.
