JBFS slab formwork gives a flat, rigid soffit for casting floor slabs. Angle type and folding type panels are offered, supported on adjustable props or scaffolding. Panels are made from steel sheet of 2 to 3 mm on a slotted angle frame. Steel is non-absorbent, gives a dense concrete finish and can be re-used many times. Width and length are made as required, so the panel layout can follow your slab plan.
