Structural Steel Protection

Vermiculite Gypsum Spray

Vermiculite Gypsum Spray

Structural Steel Column Cladding

Steel loses its loadbearing capacity at a temperature in excess of 550°C during a fire; therefore structural steel protection (e.g. with board, paint, spray etc) is required to preserve the stability of the building structure in the event of fire. All Promat products and systems have been tested at nationally accredited laboratories around the world to a variety of standards, e.g. BS 476: Part 21, AS 1530: Part 4, DIN 4102, ASTM E119 and EN 13381-4.
