Air-tight auto-repair model of high speed door passes through our strict test [Nov 16,2016]
We have devedopped a whole new model of Rapid Roller Door. The biggest advantage of it is 100% seal at two sides guide rails. A special zipper design is adopted to connect fabric and guide rail as a whole. In traditional rapid roller door, the space between guide rail and fabric can not be avoided. But in this new model, it is completely eliminated.
