A North Dakota manufacturer and installer is offering a line of custom-built, bi-fold doors to make work a little easier for farmers. Midland Door Solutions‘ line of bi-fold doors for large agricultural, aviation and commercial buildings also come with continual service to ensure customer needs are met for the lifetime of the door.
Midland’s bi-fold doors contain heavy-gauge steel tubing and a unique truss system that are jig welded for exceptional strength and durability. The doors do not obscure the building’s opening, and equipment can use the full height and width of the doorway when entering or exiting.
A single-latch system with a safety switch comes standard on every door for easy operation. Once closed, users can easily secure the door with one latch in the center rather than one on each end. This saves time, and the safety switch eliminates the risk of damage that can be caused when a user forgets to open both latches. With an optional automatic latch, Midland bi-fold doors can be opened with the push of a button.
Midland designs all of its bi-fold doors to open quickly and safely. The opening system has a 5-to-1 safety rating – the cables and straps that open the door can withstand stress that is five times greater than the weight of the door. Customers can choose a cable, 1/4-inch or larger, or a 3-inch nylon strap that wraps over itself to lift the door.
Midland officials say that power sources ranging from 1.5 to 4 horsepower will open their custom-made doors. Other safety features include optional integrated safety switches that stop the door if anything interferes while it is opening or closing and door sections with cold-formed steel hinges that are welded to the door’s frame and linked together with 5/8-inch and 3/4-inch cold-formed hinge pins.
