Product Overview
Steel-Ply® is a pre-engineered, factory-built, reusable concrete forming system used in handset or gang form applications for commercial or residential structures. It forms walls of almost any shape or size, with accessories available for special structures and details, and is more productive and economical than job-built plywood formwork.
Setup and stripping require no measuring, sawing, drilling, or nailing — the only tool needed is a hammer — so crews reach full efficiency with minimal training. Panels and fillers use laminated plywood mounted on rugged steel frames and can be reused up to 200 times before re-plying. All components combine into a system rated up to 1,000 psf, depending on application, with a predictable safety factor over the service life of the form, and the lightweight design keeps gang form size limited only by crane capacity.
