Most suppliers method of fixing polycarbonate is to simple fire inadequate fixings through the polycarbonate or PETG sheets directly into a steel frame. Urban Design are aware of the numerous maintenance and strength problems this causes for clients. Particularly those products suffering from the effects of wind flutter, a condition brought on by inadequate fixings pulling through sheet material which is too thin. Compromising on initial product quality will inevitably cost in future repairs. As standard Urban Design use cold formed aluminium clamping straps with full neoprene gaskets to both the straps and the steel frame to which the polycarbonate is fixed, to not only isolate the materials but also to ensure a watertight connection. In addition we use heavy duty fixings and where possible hide the fixing head with colour coded caps, as seen in the image here. For advise and recommendations on the use of polycarbonate sheeting please contact our sales department who will be please to assist you in best practice methods.
