Ready to Use Sealing Solutions
Though we are flexible in our processes, Saint-Gobain typically provides customers with a frame that features exact to door dimensions and seal geometry. The seal includes a "foot"that is either placed in the groove of the door or in the oven frame. We also can deliver seals in rings or coils. If you prefer an alternative process or system. just let us know as we can provide samples or will run Finite Element Analysis (FEA) simulation to validate your ideas!
With industrial footprints across France and Germany, Saint-Gobain Sealing Solutions provides excellent and timely service and technical support.
