Product Description
Steel fireproof and explosion-proof board is a special architectural board, with the advantages of good explosion-proof performance, good fireproof performance, light weight, and high strength; in case explosion occurs, the system has intactness, shall not crack, and can safeguard the security of important cable; in case explosion occurs, the system has thermal insulation, and the microlitre inside the system is very tiny, thus, ensuring cable can work under the normal temperature. Its application scope is very wide.
