Bottom Rolling Doors. Building the Best in the Business

WELL BILT Industries’ bottom rolling door systems have proven durability and performance.
The rolling door design is specified for openings of almost limitless width with your choice of panel configuration.

By working closely with architects, contractors and owners, we can manufacture a system that meets your specific needs or can retro-fit to meet the needs of an existing structure. Our seals offer the most reliable all-weather protection allowing for long-lasting performance reliability.

ROLLING DOOR TECH

Bottom Rolling Door Structure

All materials used for the construction of rolling door system components are new and free from defects or imperfections.

Hot rolled structural steel shapes conform to ASTM A36 with a minimum yield strength of 36,000 psi. Tensile strength is 58,000 to 80,000 psi.

Cold formed structural steel shapes, such as cee’s, zee’s and channels, conform to ASTM A570 Grade 55 with a minimum yield strength of 57,000 psi.

Welded mechanical tubing conforms to ASTM A-500 Grade B with a minimum yield strength of 46,000 psi. Typical tensile strength is 58,000 psi.

Mechanical fasteners critical to the assembly or function of a rolling door system are either ASTMA-325 or SAE Grade 5. Bottom track support anchor bolts or threaded rod may be ASTMA-307 or equivalent.

Elastomeric sealing elements that seal the sides and bottoms of the door systems are fabricated using EPDM type 40 elastomer. EPDM is for outdoor and high temperature applications. It resists ozone, steam, water, oxygenated solvents as well as animal and vegetable oils.

Bottom Rolling Door Operation

WELL BILT Industries offers a patented rolling door operator adaptable to either in-the door or out-of-door installation. Most WELL BILT Industries rolling door systems can be furnished or retrofitted with operators.

To guide the top of the door, WELL BILT Industries offers both fixed and telescoping systems. The fixed top guide system can accommodate a maximum total vertical deflection of 3 inches. The telescoping top guide system is used where total building vertical deflection is greater than 3 inches or where positive engagement of the top guide is required because of wind uplift conditions. Both systems utilize sealed ball bearings for guide and carrier rollers. The fixed top guide system engages a structural angle guide beam, and the telescoping top guide system engages an “I” or wide flange beam. Either are provided by WELL BILT Industries to be installed by others. Lateral supports for the top guide beams are to be supplied by others and are to be spaced 8′ to 10′ apart.

Door Horizontal members

Bottom beam or sill shall be structurally capable of supporting the total weight of the finished door and transmitting that weight plus the lateral force due to wind loading through the bottom rollers to the bottom track system.

Top beam or header shall be structurally capable of transmitting wind load forces into the top guide system.

Intermediate horizontal members or girts are normally fabricated from hot rolled structural shapes unless weight is a consideration then cold formed shapes may be substituted. Members are typically spaced so as to provide proper vertical spacing for attaching the customers exterior sheeting.

Intermediate vertical members shall be hot rolled or cold formed structural shapes as required to accommodate imposed loads.

Diagonal bracing shall be of cold formed structural shapes or welded mechanical tubing.

Construction – Except for small door sections which can be transported in one piece, WELL BILT Industries rolling doors are fabricated in sections which can be easily shipped. These sections are then bolted at the job site to clips that are welded to the vertical members.
