CITY-GATES CG750 High Stress Door

A variation on our CG650 that meets Miami Dade County Hurricane requirements


Our Model 750 Certified Wind Load Rated Door is designed and manufactured with durability, quick installation and ease of maintenance in mind. Standard features eliminate the need for options or upgrades. The best door, the best value.


The 26 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 in accordance with ASTM-E330, the Model 750 meets the requirements of Standard Building Code, International Building Code and Florida Building Code. Available in sizes through 10’0” x 12’0” and in over 20 different standard colors.


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 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.


Roll Up Doors Direct 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 Roll Up Doors Direct 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.
