To enable a high speed operation, robust spiral brackets having efficient spacing are provided to guide the plurality of sectional slats. Durable and low noise signature rollers are used. A unique assembly configuration of the slats and the tracks guiding the rollers enable quick replacement of each individual roller without disassembling the door. A double-belt counter weight mechanism balances the door and incorporates safety sensors that prevent loosening the belts when the door is jammed. The belts are further adjustable using ratchets such that adjustment for the horizontal balance as well as weight position is made effortless. In all, the high speed roll-up door using sectional slats performs faster and quieter, withstands greater loads, and lasts longer than other existing roll-up doors with spiral brackets.
