APPLICATION AND USE
Rolling Economy Grille doors as manufactured by Alpine. Econo
grille doors are designed for easy operation and long life use with
minimum maintenance required. The Alpine Grille offers security and protection
as well as the ability to visually observe what is behind the door when fully
closed. Ideal for stores, malls and shopping centers.
GENERAL
Opening preparation, miscellaneous or structural metal work, access doors,
finish or field painting, field electrical wiring, wire, conduit, fuses and disconnect
switches are in the Scope of Work of other divisons or trades.
CURTAIN
Curtain grille construction consists of the Alpine Straight Pattern 6” with aluminum
vertical links and horizontal PVC sleeves. There is a choice of 4 standard
colors: bronze, black, silver, or gold. Continuous solid 5/16” hot dipped
galvanized horizontal rods spaced 2” o.c. are to be covered with tubular spacers.
Continuous end links are made to prevent the curtain from leaving the
side of the guides. The bottom bar consists of an extruded aluminum “T” bottom
bar.
BRACKET PLATES
Steel plate not less than 1/4” thick. The drive end bracket plate is fitted with a
sealed ball bearing and the bracket plates are mounted to the wall mounting
angles with 1/2” fasteners.
GUIDES
Produced from roll formed steel with return retainers to prevent the grille from
leaving the guide rails. The mounting angles are a minimum of 2 1/2” x 2 1/2”
x 3/16” angles. (Option: 3” mounting tube for up to a 20’wide door and 4”
mounting tube for a door over 20’1” wide. See Mall Dawn for mounting to tube
configurations.)
SPRING COUNTERBALANCE
To be housed in a steel pipe with a diameter and wall thickness to restrict maximum
deflection to 0.03” per foot of door width. Hot rolled A36 material.
Springs are of the helical torsion type which are designed to include an overload
factor of 25% for optimum ease of operation. The springs are grease
packed and mounted on a cold rolled steel inner shaft. Spring tension is
adjustable from the outside of the end bracket plate. Sealed ball bearings prevent
wear on the pipe shaft. Life cycles from 10M to 400M.
