JBFS wall formwork is a multi-purpose system of standard, flexible, circular, haunch and internal-corner plates with channel soldiers, used to cast walls of any length. Panels are made from mild steel sheet on a slotted angle frame with stiffeners. They are assembled with channel soldiers, clamps and wedge pins. Steel gives a smooth, exposed concrete finish and can be re-used many times, which keeps the cost of each pour low.
