The 24-gauge corrugated door curtain is manufactured from full hard galvanized grade 80 steel and coated with Super Durable polyester paint that is backed by a 40-year film integrity and a 25 year no-fade limited paint warranty. Independently tested, the Model 850 meets the requirements of the Miami-Dade County Product Control Division for the high velocity hurricane zone (HVHZ) of the Florida building Code. Design wind load is rated +46 PSF and -54 PSF. Available in opening sizes up to 8’8” x 10’0” and in white only.
During production, each spring is coated with a generous amount of grease that penetrates the pores of the spring with additives, displacing moisture and preventing the formation of rust and corrosion. In addition, this process relieves the friction created between spring coils thereby providing smoother door operation. Finally, the spring and axle assembly is enclosed in a tube to protect them from the elements encountered throughout the life of the door.
Doors stacked on top of each other in transit are going to shift… unless they can be packaged in a way to minimize the sliding that occurs during that time. Janus has found the way. As an option, we can suspend each door individually in crates. Whether they travel down the block or across the country, compaction damages, door abrasion and chatter marks are virtually eliminated.
The Janus ratchet tensioning device supplied as standard equipment on our door offers a simpler method of tensioning while more accurately fine tuning all the springs on the door at the same time. There is no extra hardware required. Eight different positions on the tension wheel allow one to perfectly balance the door every time. There are no pins required to hold the tension on the spring. You simply just click it.
Janus supplies radial ball bearings at no additional cost. Our permanently lubricated bearings require no maintenance and are guaranteed to last the entire life span of the door.
This design, noted for its durability and smoother operation with commercial applications, has now been incorporated into the Janus self-storage door. The tube housing protects the springs and strengthens the axle. Eliminating axle push and shift that can occur with a live axle, the dead axle design allows for a straighter travel path of the door curtain in the guides. The biggest feature of this design is that it affords the fine tuning of any spring adjustment to equally affect all springs on the door at the same time.
Our patented mini latch features a cover plate made from a heavy gauge yellow zinc coated steel or optional stainless steel. In addition, the latch cover protects the slide from tampering by completely covering the slide, with the exception of a tab used to operate the latch. To further secure the door, the latch’s two-inch throw, with its magnetic properties, can be incorporated with the new guide-mounted security devices. This versatile design affords you the ability to utilize padlocks, cylinder locks or both.
