Rolling Doors
Product Details
An optional hood cover encloses curtain coil and counterbalance mechanism and is made to match the grille finish.
The counterbalance assembly consists of a spring barrel which serves as a load-carrying beam. It encases the counterbalance mechanism and provides the axis around which the curtain coils. (Deflection is limited to 0.033" per lineal foot of span.) If required, barrel rings of malleable iron or stamped steel may be provided to assure the proper counterbalance. Oil-tempered, torsion-type counterbalance springs are wound from heat-treated steel, providing accuracy in balancing the door. Barrel plugs connect ends of springs to barrel and tension rod. Tension rod of steel shafting holds fixed ends of springs and carries torsion load of spring counterbalance. A spring tension adjusting wheel is normally mounted outside the bracket on end of tension rod. An inside adjusting wheel for "tight" side-room applications is available in limited sizes.
Operation can be manual push-up, chain, hand crank, or motor-operated. Door mounting can be self-supporting, using structural tubes, or directly attached to the building structure. Hand crank may be fixed or removable.
Powder coating is available in multiple colors. Powder coating is a dry finishing process in which finely ground particles of pigment and resin are electro statically charged and sprayed onto the electrically grounded parts of rolling doors. These charged particles adhere to the rolling door parts until they melt and fuse into a solid coating in a curing oven. The result is a finish that radiates beauty and smoothness for an aesthetically pleasing grille.
Aluminum grille patterns are available in clear anodized, mill (standard), or bronze anodized finishes. Optional materials are finished stainless steel and/or galvanized steel.
Optional cylinder lock assembly in bottom bar activates concealed 3/8 steel tamperproof lock rods. The lock uses standard mortise cylinder, and is also available with an optional removable core. Center locks are available up to 25' wide.
The standard features of the rolling grille doors include 5/16 galvanized steel horizontal rods, continuous from jamb to jamb, and covered with aluminum tubes. Vertical links are aluminum. End links ensure that the grille cannot be pulled from guides. The links are made of 1/8 (standard) or 3/16 (heavy-duty) aluminum. The bottom bar is a tubular aluminum extrusion, fitted with nylon end caps which act as bearing surfaces.
