Rolling Grilles are designed to maximize
security, visibility, and ventilation. The durable construction technique used
ensures that the grilles will offer many years of reliable and consistent
performance.
Materials
& Construction
Standard features 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 bottom bar is a tubular
aluminum extrusion, fitted with nylon end caps which act as bearing
surfaces.
Optional cylinder lock assembly in bottom bar activates concealed 3/8” steel
tamperproof lock rods. Lock uses standard mortise cylinder, and is also
available with an optional removable core. Center locks available up to 25′
wide.
Aluminum grille patterns are available in clear, mill, or bronze
anodized finishes. Optional materials are #304 finished stainless steel and
galvanized steel.
Powder coating is available in 180
colors. Powder coating is a dry finishing process in which finely ground
particles of pigment and resin are electrostatically 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.
Operation can be manual push-up, chain, crank, or
motor-operated. Door mounting can be self-supporting, using structural tubes,
or directly to the building structure.
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 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 torsional load of spring
counterbalance.
Spring tension adjusting wheel is normally mounted outside the
bracket on end of tension rod. Inside adjusting wheel for tight side-room
applications is available in limited sizes.
The optional hood cover encloses curtain coil and counterbalance
mechanism and is made to match the grille finish.
