Recently dp Doors installed a 3.5 tonne roller shutter door at Sheffield Forgemasters for an opening 12mtrs wide x 9mtrs high this was part of a 4 door package to replace damaged doors after the devastating floods of 2007
Total consideration was given at the design stage for curtain wind resistance, barrel deflection and tensile and shear stress to all fixings. The installation was completed 2 days before a visit by HRH Prince Charles !
