Whether you’re constructing awnings, banners, truck tarps, pool covers, inflatables, tents, membrane structures, or any other project from industrial fabric, Leister fabric welding tools give you superior results. Done correctly, heat welding provides a bond that is as strong as the original material; secure enough for outdoor or high-strain installations, welds are clean and accurate enough to join banner pieces. Heat welding can be used for vinyl (including PVC and PVDF), PE (including CSPE), PP, and rubber (including EPDM) coated fabrics and membranes, among others.
