APPLICATION AND USE
Alpine Redi-Storm Doors are highly used throughout the Florida Coastline where there is a high level of storm’s and gusty wind conditions specifically during the months of August, September and October.

GENERAL
Manufacture Florida Department Of Community Affairs Redi-Storm doors with
a design pressure of +60 psf & -60 psf, 1.5 Safety factor, 90+/- psf, by Alpine.
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
Constructed of interlocking, roll-formed, 2 3/4” galvanized steel flat slats. G90
coating exterior, G60 coating interior, Structural Quality Grade C, (ASTM A-
653/A-653-M) in 21 Gauge. Optional Gauges in 20 and 18. Finish Options: baked enamel or powder coated.

GALVANIZED ENDLOCKS
Hot dipped galvanized cast iron endlocks and windlocks riveted to the ends of every slat, with (4) four, 1/4” rivets which prevents lateral movement and limits slat deflection of the curtain.

BOTTOM BAR
Two roll-formed galvanized steel angles , as per ASTM A-653/A-653-M , Measuring 2”X2”X1/8”,equipped with vinyl weatherstripping which extends into the guides.

GUIDES
Guides are designed to meet Florida Department Of Community Affairs specifications using structural steel angles, (ASTM A36) with a minimum thickness of 3/16”, and a minimum 1/4” slotted connections with removable bellmouth curtain stops to allow for curtain maintenance without removal of the guides. Option: Vinyl Weather Seals.

COUNTERBALANCE ASSEMBLY
Steel pipe barrel of a size capable of carrying a curtain load with a maximum deflection of 0.03” per ft. of door width. Heat treated springs encased in a steel pipe and designed to include an overload factor of 25% to ensure minimum effort to operate. A sealed and prelubricated ball bearing is present at the rotating support point. (A torsion spring charge wheel is used for applying spring torque and for future adjustments). Stainless steel or hot dipped galvanized pipe assemblies are available. Option: High Cycle Springs can be designed to satisfy up to 400,000 life cycles.

PIPE SHAFT
A solid shaft with a minimum thickness 1-1/4” for 4” pipe, 1-1/2” for 6” pipe
and 1-3/4” for 8” pipe. - (1018 cold rolled round.)

BRACKETS
Steel plate not less than 1/4” thick with ball bearings at rotating support points. When bolted to the wall the mounting angle supports the counterbalance assembly and forms an end enclosure. (Option: Stop Lock Bearing which prevents the door from free falling in the event of a drive operation failure.

HOOD Hexagon (Option: Square or Round)
#22 ga. galvanized steel is formed to fit the contour of the end brackets. Finish Options: phosphate, baked enamel or powder coated.

FASCIA GALVANIZED (OPTIONAL)
Useful where the area behind the hood is open. Especially applicable with pre-engineered buildings. 61-RS WindStorm-Rated Assemblies Redi-Storm 20’ - U.L.
Redi-Storm 16’ - U.L/Dade County Redi-Storm 12’ - U.L. Through 30’ High.

STANDARD FLAT SLAT IS UPGRADEABLE TO INSUL-SOUND OR INSUL-VAPOR Redi-Storm Door

U.L. TESTED
+60 PSF -60 PSF

OPERATION
Available in push-up, hand chain, hand-crank, or motor operation. For other optional features see the motor operators section in this catalog.

LOCKING
Doors are equipped with padlockable slide locks for latching and locking the door on the coil side of the bottom bar. Electric Interlocks recommended for motorized doors.

FINISH
Slats are prepared with a minimum galvanizing of G-90 (exterior). The hoods are galvanized and other exposed ferrous surfaces are prime painted or powder
coated.

TEST METHOD
Alpine door models Redi-Storm 20, Redi-Storm 16, and Redi-Storm 12 were all tested in accordance with ANSI/ASTM E320-2; ANSI/ASTM E1886-005; Dade
County Protocols PA-201, PA-202, and PA-203.
