The Steel-Ply forming system has a strong steel frame and is backed with high-density plywood face. Wall ties are inserted between the modular units and secured with two wedge bolts. Forms are adaptable to straight or curved walls allowing you to use them on residential, commercial or industrial applications. These forms can be set horizontally or vertically and are easily stacked. Using standard flat steel-ply panels and fillers you can form most curved walls about as fast as straight walls.
