DBCI Commercial Roll Up Door Information

When It Comes To Commercial Roll Up Doors,
There Are A Few Things You Should Know:

Commercial doors have to be tough — tough enough to withstand constant use and occasional abuse, both natural and manmade. This toughness is a result of a few critical parts and features, including:

Curtain:

The two most important elements of the curtain are what it’s made of and what it’s painted with. Hard, Grade E steel ensures strength and durability. A siliconized polyester finish replaces older polyester paint finishes, which are recognizable by severe chalking and fading caused by UV rays. DBCi curtains are coated with a silicon polyester paint that is so resistant to UV light rays that some colors have a 25-year warranty.

Guides:

Guides are the key framework/support for the door and provide the required durability. They should be constructed of 12- to 14-gauge industrial-grade galvanized steel. Abrasive-resistant polyethylene wear strips reduce friction and ensure a quiet and smooth operation.

Torque-Tube Assembly:

As it is for the curtain and guides, industrial-grade steel is the material of choice for exceptional durability for the axle and drums. The door drums must be designed and engineered specifically for commercial application to ensure product integrity, long life and high-capacity use. Steel ball bearings are preferable to nylon or plastic bushings, which can disintegrate under heavy use.

Torque Adjustment:

Fortunately, innovations in torque adjustment make adjusting roll-up doors easier, safer and faster. In most cases, one service technician can adjust a DBCi commercial-grade steel curtain roll-up door in less than ten minutes.

Springs:

This is the most critical mechanical part of a steel curtain commercial-grade roll-up door. For maximum reliability, DBCi uses only oil-tempered torsion type springs for its commercial-grade steel curtain roll-up doors. Coordinating the design of a commercial-grade steel curtain roll-up door with the proper spring assembly ensures longer and more durable usage with minimal maintenance. In independent tests, DBCi’s commercial-grade steel curtain roll-up door exceeded 40,000 openings and closings before any maintenance was required. Although there is no such thing as a maintenance-free door, at DBCi we engineer our doors to be maintenance-simple: easily visible for inspection and accessibility.

Wind Load Certification:

Fueled by the constant changes in local and national building codes, as well as increasing insurance costs, choosing a door with a validated wind certification can dramatically reduce maintenance, replacement costs and minimize downtime.
