Handset Steel-Ply

The Steel-Ply forming system is a pre-engineered, factory-built, reusable concrete forming system. It may be used in handset or gang form applications, for commercial or residential structures. This system can form walls of almost and shape or size. This system is more productive and economical than job-built plywood formwork or other forming methods. Steel-ply saves time due to its ease of setting up and striping down. No measuring, sawing, drilling, or nailing is required. Minimal training is needed since it has no top or bottom, left or right, and can be used vertically or horizontally. Steel-ply saves material by coming in a variety of standard sizes which can be formed to create virtually any dimension.
