- Mounting: The door can be face mounted or mounted between jambs of a prepared opening.
Opening preparations, miscellaneous or structural steel, field painting or finish, access panels, electrical wires, wiring, switch connection, conduit will be handled by the appropriate trades.
• Product Specifications
-Slats: Aluminum panels extruded in continuous lengths of 6063-T6 anodized aluminum, cut to specific sizes for proper design and operation, interlocked alternately with solid Lexan (poly-carbonate) panels to form curtains.
-Gauge: Dual-faced aluminum panels shall have thickness of 16 gauge on each face. Lexan panels shall have thickness, where it is the minimum, of 0.15625¡± and, where it is the maximum, of 0.40625¡±.
-Endlocks: To accomplish slat alignment and serve as a wearing surface endlocks are fitted to each end of alternate slats.
-Anodizing: All aluminum parts shall be anodized. Mill finish and shiny bright-dip anodized finish is also available.
Curtain is reinforced with an extruded aluminum tube that can be further reinforced for wider openings.
Guide and Wall Angle Assembly
-Guides/Wall Angles: Extruded aluminum channels at both sides shall serve as guides. Wall angles shall be either aluminum or steel with minimum thickness of 1/8¡±. Structural steel tubes can also be used in lieu of wall angles.
-Depth of Guide: To be of appropriate size to allow slate penetration and to restrict horizontal slat movement.
-Bracket Plates: To support the curtain and the counterbalance, the bracket plates shall be provided with minimum thickness of 1/4¡±.
-Drive End Bracket Plate: The bracket plate on the drive-end is to be fitted with a sealed ball bearing.
-Counterbalance: Housed in a steel pipe, maximum deflection to 0.03¡± per foot of door width is achieved by having the appropriate diameter and wall thickness.
-Springs: Helical torsion with a 25% overload factor for ease of operation and are greased packed mounted on a cold rolled steel inner shaft.
-Spring Tension: Can be adjusted from outside of end bracket plate.
-Ball Bearing: Sealed in order to minimize wear of pipe shaft rotation around inner shaft.
-Hoods: To completely enclose curtain and counterbalance, hoods shall be provided from #24 U.S. Gauge galvanized steel.
-Reinforcing: Can be reinforced laterally to prevent sag.
-Intermediate Hood Supports: Provided where door width exceeds 16¡¯.
Operation can be manual push-up, chain hoist, waist high crank hoist, or electric motor operated.
-Integral Gearing: Power operator can serve as an additional locking for the door.
-Hand Chain Lock: Locking bracket can be provided.
-Cylinder Lock: System is installed in bottom track and can be key or thumb knob operated.
Aluminum surfaces are anodized and can be powder coated in various colors upon request.
- Bottom Track: Bottom track can be sloped to match contour on finished floor or can be notched to match obstruction on finished floor.
- Sensor Edge: An electronic sensor edge can be added to power operated doors to reverse the door travel upon encountering an obstruction for safety.
- High Cycle Springs: Can be obtained for motorized doors that require 50,000 to 100,000 cycles. Very high cycles in excess of 100,000 are also available.
- Locking: Thumb turn/key cylinder locks and multi-cylinder locks are available.
- Aluminum Surfaces: Aluminum surfaces can have mill finish or clear anodized finish.
- Pass Door: Hollow metal pedestrian door within rolling door can be obtained in a 3¡¯ x 7¡¯ or 3¡¯ x 6¡¯ 8¡± size. Hinged to rolling door guide the hollow metal door frame will swing clear of opening when desired. Hardware includes heavy duty hinges and handicap-level lock set.
