A. Type: Roll-up Doors: are to be the Model # 501 series as manufactured by U S Door & Building Components.
B. Operation: to be manual push-up.
C. Mounting: to be interior face mounted on a prepared steel, masonry, or wood opening.
D. Opening preparation: miscellaneous or structural steel, access panels, and finish or field painting, are in the scope of the work of other sections or trades.
A. Curtain: made from hot-dipped galvanized steel roll formed into a corrugated sheet, interlocked and seamed together to form a continuous curtain for full height of the door.
B. Poly Vinyl Chloride Strip: of 1" (25mm) width, stapled uniformly to the exterior side of the curtain, along both edges, to act as a wear strip, to prevent steel to steel contact with the curtain and guide, and to act as a spacer allowing the curtain to roll-up in a cylindrical fashion minimizing any nesting of the curtain while the door is in the open position or during operation. Provides required space between curtain surfaces while in operation to minimize surface paint scratches and curtain friction. Allows for overall door longevity and quiet operation.
C. Finish Coat: prior to roll-forming, curtain is pretreated, then painted with a prime coat and a top coat of medium gloss high temperature siliconized polyester paint. Standard colors available are: Gloss White, Satin White, Chocolate Brown, Natural Tan, Lightstone Tan, Public Orange, Urgent Orange, Hunter Green, Dark Teal, Marine Green, Duro Bronze, Royal Blue, Polar Blue, Cobalt Blue, Lighthouse Red, Garnet Red, Calypso Green, Bright Yellow, and Cardinal Red.
