No matter what type of opening you are working on, Door Systems of Alaska has a solution. For industrial, mining, and aviation applications, we offer custom built vertical lift, four-fold, and sliding doors through Electric Power Door. For interior and exterior separation and security, we offer hangar style folding doors that are counterbalanced and can be fully glazed with no cables or straps for unobstructed vision at the face of the door. The Renlita S-2000 and S-3000 offer a clean look and are capable of a wide range of sizes from small openings to widths up to 90’. For high speed doors and impact resistant doors, Cornell and Rytec can provide car dealerships, industrial, warehousing, or any other application where the need for high use, high cycle, and fast operation is required.
