Self-Storage Door Features
Features Include:
The Series 850 Door was designed to meet stringent wind load requirements for mini warehouse applications while still providing the best door operation in the industry.
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 Florida Product Control Division for high velocity hurricane zone (HVHZ) of the Florida building Code. Design wind load is rated +46 PSF and -54 PSF. Opening sizes up to 8’8” x 10’0”
in white only.
DOOR SPRINGS 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 from the elements encountered throughout the life of the door
RATCHET TENSIONING DEVICE 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.
RADIAL BALL BEARINGS are supplied at no additional cost. Our permanently lubricated bearings require no maintenance and are guaranteed to last the entire life span of the door.
DEAD AXLE & TORQUE TUBE ASSEMBLY This design, noted for its durability and smoother operation with commercial applications, has now been incorporated into the 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.

High Quality Arch Buildings by Duro Steel
Duro Span hut is defined as any self-supporting structure, usually in an "arch" or curved shape. There are no interior posts, trusses or support beams of any kind. The exterior sheeting is the building. To assemble an Duro Span building, you first layout each individual section of the arch on the ground (each section is usually no bigger then 8-12 feet long (3-4 meters).
You bolt all the sections together to make the first arch. You pull up the assembled arch and attach it to its foundation. Each additional section is assembled in the same manor and attached to the other standing arches. Each arch is usually about 2 feet wide (1/2 meter). To make the building longer, just add more arches. There is no limit as to how long this building can be. End walls may be provided by the manufacturer, or you can build your own. Unique to the Duro Span arch type steel building is you can leave one or both ends completely open without losing the integrity of the structure.
