Steel structure (steel beams/steel columns) fireproof coating system
The critical temperature of steel components is between 550℃ and 620℃, and it is prone to damage or collapse. The building design fire protection regulations require the fire resistance limit of first-class building components. The beam has a fire resistance limit of 120 minutes, and the column has a fire resistance limit of 180 minutes. The安心fireproof board is used to slow down the temperature rise of the steel， maintaining the stability of the steel and providing sufficient time and guarantee for rescue.
Application
1. Various steel structures in buildings such as factories, residences, commercial buildings, and light steel structure houses for villas, including steel beams and steel columns.
2. Steel structure roof systems.
3. Truss and other steel structure support system
