What Janus makes

• Self storage doors: roll up doors for storage units and hallways, made since 2002. Janus calls its 650 Series the most installed roll up door in self storage.
• Commercial sheet doors: nine series of roll up sheet doors, from the light duty 1000 Series to wind load and Miami-Dade certified models, up to 20 x 18 ft.
• Rolling steel doors: ten series of service doors, fire doors, grilles and counter shutters. Janus also owns ASTA America, which makes rolling steel doors under the same series numbers.
• Made in the US: Janus builds doors in Georgia, Texas and Arizona.

Every Janus self storage roll up door has pre-lubricated springs enclosed in a tube, a dead axle and barrel assembly, a ratchet tensioner that sets both springs at once, and a 26 gauge (24 gauge on the 850) galvanized steel curtain in more than 30 colors.

All four come insulated on request, with side and top draft stops for climate controlled units. Janus also makes MDS swing doors and locker doors for spaces where a roll up door doesn’t fit.

Smart locks. Janus sells Nokē Smart Entry, smart locks and keypads that tenants open with a phone app. The Nokē Ion mounts inside the door track of Janus doors; the battery powered Nokē Infinitē is made for existing doors.

For heavier openings Janus makes ten rolling steel series in five groups:

• Service doors: 300, 400, 400HP and 600 (insulated). The 400 Series goes up to 40 ft wide or 30 ft high.
• High performance doors: 400HP and 800HP, opening at up to 24 inches per second.
• Fire doors: 500, 500i and 550, with UL fire ratings up to 4 hours on the 500 Series.
• Rolling grilles: 800 and 800HP.
• Counter shutters: 700, and the 550 fire rated shutter.

These are the same series numbers ASTA America uses. Models, gauges and wind load ratings are on our ASTA America rolling steel doors page. Rolling fire doors need a yearly drop test: see fire door drop testing.

Janus’s operation and maintenance manual for its rolling sheet doors gives a few checks a facility manager can do by hand and eye:

1. Feel the balance. The door should move easily near the fully open and fully closed positions; it may take more effort through the middle. When fully open, it should stay up with the bottom bar resting against the head stops.
2. Know the limits. Janus says a door should take no more than 30 lb of force to open by hand, or 35 lb on a hand chain. Easy to close but hard to open means the springs need more tension; hard to close but easy to open means less. Both are jobs for a technician.
3. Look at the guides. Every guide fastener should be in place, the guides should not be bent or crushed, and the head stops should be secure at the top.
4. Look at the curtain. Latches, slide locks and windlocks must stay fastened to the curtain; windlocks should never be removed. Check the wear strips and weather seals.
5. Motor operated doors: test the photo eyes or sensing edge at least weekly by breaking the beam or pressing the edge at both ends, and check the operator every quarter. If the motor strains to open the door, close it, switch to manual operation and call for a spring check.

A door with a worn, damaged or unsafe part should be taken out of service until it is repaired. Janus also asks that the safety labels on the door stay clean and readable.
