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

SPRING SHAFT ASSEMBLY
The 1200F counterbalance assembly is encased in a steel pipe barrel of proper material thickness so that deflection does not exceed 0.03 inched per lineal foot of door width.The counterbalance is designed with an oil-tempered helical torsion spring engineered for 25,000 cycles and easily regulated by means of o tension- adjusting wheel mounted on an outside bracket. High Cycle Springs are available upon request.
