- 26 gauge hot-dipped galvanized steel curtain with a baked-on silicone polyester top coat.
- dipped galvanized steel (18 gauge 150C, 16 gauge 157C and 12 gauge 160C).
- metal contact and muffle door noise.
- Curtains are prepainted inside and out to inhibit rust. Hot-dipped, galvanized steel is painted with primer and given a tough oven-baked silicone polyester top coat, to provide the most rust-resistant steel door available.
- Heavy-duty bottom bar withstands the external elements.
- Full bulb-type bottom weatherstrip ensures proper fit along irregular floors.
Corrugated Curtain – 26 gauge sheets, roll formed from ASTM A 653 grade 80 full hard steel, interlocked and seamed together to make a continuous curtain for full height of door. Full height felt tape on back of curtain prevents nesting and reduces paint rubbing. Available in sizes up to 12′ x 14′ (3.7 m x 4.3 m).
Finish Coat – Curtain is galvanized and prepainted with long-lasting silicone polyester paint.
Guides – Roll formed, 18 gauge galvanized guides are fitted with dual polyethylene wearstrips to reduce friction and muffle door noises. All guide attachment to jamb is performed through the guides without the addition of clips welded to the back of the guides.
Mini-Latch – Standard stainless steel cover, slide and four attachment bolts are factory installed. Latch accepts all industry padlocks, including 7/16″ (11.1 mm) diameter shanks. Provision for cylinder lock is included.
Brackets – Factory installed galvanized reinforced 12 gauge brackets are designed to snap easily onto the guides, reducing installation time.
Bottom Bar – Roll formed clear acrylic coated galvanized steel reinforced with a 2″ x 1-1/2″ (50.8 mm x 38.1 mm) 11 gauge full width galvanized steel angle. The PVC bulb astragal provides positive contact with the floor. Lift handle(s) installed on exterior side of bottom bar and a nonrotting pull rope is attached to the inside angle.
Counterbalance – Oil-tempered helical torsion springs are factory lubricated to minimize friction and corrosion while increasing the spring cycle life. Spring wire conforms to ASTM A 229. All drums are fitted with a grease-filled, shielded radial ball bearing to contribute to a smoother operation and reduce wear and friction. Barrel is full width galvanized steel, which totally encloses the drum, springs and axle.
Ratchet Spring Tension Assembly – Factory installed on the end of the door axle and allows precise fine tuning of the initial spring tension. Increments of 1/8 turn are possible. Tensioner adjusts both springs equally at the same time from only one end of the door.
Wind Loading – Clopay WINDCODE® W3, W4 and W8 are available.
