Finish options: Choice of 188 ExoShield™ Powder Coat Colors.
> Click here for available Powder Coating colors.
GALVANIZED ENDLOCKS/WINDLOCKS
Ductile Cast iron, hot-dipped galvanized endlocks/windlocks are riveted to the ends of the slats with 1/4” rivets. Option in brass material which prevents sparking. Furnish windlocks based on wind load specifications.
BOTTOM BAR
Two galvanized roll-formed steel or structural steel angles which are designed to reinforce the bottom of the curtain. Equipped with rubber astragal or a sensing edge which extends into the guides. Galvanized steel as per ASTM-A653/A653-M
OPTION: Exo-Shield™ Powder coating to match curtain.
BRACKETS
Alpine’s Grey ExoShield™ powder coatedCarbon Steel plates are not less than 1/4” thick with ball bearings at rotating support points on the drive bracket. When bolted to the wall, the mounting angle that supports the barrel/pipe 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.
GUIDES
Alpine’s Guide system is designed using structural steel angles with a minimum thickness of 3/16” meeting the ASTM A36 Standard that are bolted together with ⅜” fasteners in 1-¼ ” slotted connections bolted at a minimum 24” on center. One inch spacing of the guide channel ensures smooth operation. Vinyl clip on guide weather seal is standard.
SPRING COUNTERBALANCE
Pipe shall be manufactured with a diameter and wall thickness to restrict maximum deflection to 0.03” per foot of door width. Springs are 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. Sealed ball bearings as described above are designed to prevent wear on the shaft at each end of the pipe/barrel. Life Cycle: 20,000 up to 400,000.
HOOD Hexagon (Option: Square or Round)
Made from #22-gauge galvanized steel as standard and formed to fit the contour of the end brackets. Optional material in stainless steel or aluminum. Equipped with a neoprene air baffle. Finish Options: #4 stainless steel or powder coated to match curtain.
LOCKING
Option 1: Slide bolt locks on the bottom bar.
Option 2: Cylinder locks. (Electric interlocks are recommended for motorized doors to prevent damage.)
Option 3. Motor acts as lock.
HOT DIPPED GALVANIZING (OPTION)
Applied to the guides, brackets and gears in addition to Standard Specifications. Applied where conditions of extreme or unusual atmospheric contamination is present. As per ASTM-A123.
(Pipe Shafts available with Zinc Enriched Powder Coating or Stainless-Steel.)
FASCIA (OPTIONAL)
Useful where the area behind the hood is open, as seen in a between jambs type mounting configuration or other condition that exposes the opposite of coil side. Especially applicable with pre-engineered buildings. Finish is to match curtain.
Doors can be manual push up, hand crank, hand chain or motor operated. All operators can be adapted to specific conditions.

SAFETY ENTRAPMENT PROTECTION
Option 1: Electric Monitored/Non-Monitored Sensing edge with a coil cord.
Option 2: Photo safety sensors mounted to the guides 6” above the finished floor that project an infrared beam across the width of the door. Breaking the beam while the door is in motion will result in the immediate stop of downward travel and reverse the door to reopen to the top limit.
ACCESS CONTROLS
Optional control stations are available as Push Button Control Station or Key Control Stations. Special Control Stations(NEMA 4) are also available. For more information consult factory.
