Wolf3101;1236502; said:What I found is an extruded aluminum channel that can be cut an welded in place The channel cross section is in the shape of a lower case h <---- the bottom section of the h slips over the cut edge of the window opening and the upper section forms a grove to hold the silicone bead and the acryllic pannel. The channel is tack welded in place and the open spaces are filled with non-toxic expanding foam. The company I located has channel stock like this on hand and is willing to custom manufacture channel in case the container tanks ever go into any sort of limited production.
Are you talking about welding the aluminum channel to the steel container shell?
