Aluminum Grille Doors are ideal for a diversity of commercial and residential application requirements ranging from shopping-mall security to garage entrances. Aluminum Grille Doors can be motor, chain hoist, crank or manually operated. To achieve highest product quality Aluminum Grille Doors are manufactured with solid aluminum bars, rather than hollow tubes, running the full width of the opening. These bars are then connected with vertical aluminum links, with double-single-double configuration, kept in place with aluminum spacers resulting in a stronger more reliable door.

- Curtain: Solid aluminum bars, extruded in continuous length, of 5/16" diameter, placed horizontally with a center to center spacing of 1-1/2". Aluminum spacer tubes shall be provided at least every 12" vertically. Double-single-double configured vertical aluminum links shall be provided every 9" horizontally.
- Endlocks: To accomplish slat alignment and serve as a wearing surface endlocks are fitted to each end of every bar.
Bottom Track
Curtain is reinforced with an extruded 6063-T6 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". Whenever required, structural steel tubes can be used in lieu of wall angles.
- Depth of Guide: To be of appropriate size to allow curtain penetration and to restrict horizontal curtain movement.
