Rolling and Bifold Doors - September 2018

Rolling and bifold doors featured in Metal Architecture's September 2018 issue.

AeroDoor International's bottom-rolling doors are customized to accommodate roof deflection, clear opening dimensions and wind-load criteria. They are manufactured with structural steel and configurations include bi-parting doors, single-slide doors and floating doors. Optional features include tail doors, fuselage apertures, explosion-proof motors and controls, stainless hardware, linear cable systems and safety edges.

CornellCookson’s ControlGard rolling door hoist controls operation; it stays in place unless a user pulls on the chain. The ControlGard chain hoist has a brake integrated into the chain hoist mechanism, which stops downward travel when a user lets go. It requires approximately 3 1/2 inches of side clearance.

DBCI 2500 Series doors are heavy-duty sheet doors for warehouses and freight buildings. They feature deep engagement guides for durability and long-term performance. The 2500 Series doors have 10-gauge steel slide bolt locks. They are wind rated to 12 feet wide and approximately 90 miles per hour.

Midland Door Solutions’ Hydraulic Doors have all-steel construction. Their 4-inch tubular steel frames are assembled and jig welded. A 1-inch steel plate secures hydraulic cylinders to the doors. Hinge pins, 3/4-inch or larger, secure all attachments. Hydraulic Doors have a minimum 3/8-inch tube jamb thickness, and 3/4-inch steel plates anchor them to the bottom jambs.

Powerlift Hydraulic Doors’ Aircraft Hangar Doors have all-welded construction. Their hinge blades have a solid pass-through attachment with multiple weld points for reinforcement. The door hinges have a 1-inch diameter shaft that runs in greaseless bushings. The hinge bushings consist of a steel and porous bronze matrix that is impregnated with a synthetic fluoropolymer.
