Steel Protection

Assured level of fire protection to structural steelwork

British Gypsum steel protection specifications give an assured level of fire protection to structural steel. They present high quality claddings with or without supplementary framing. They employ either direct board to board fixing or are based on the lightweight steel framework clad with fire protective boards and are fully compatible with lightweight partitions, wall linings and ceiling systems.
