Inorganic Inflaming Retarding Color steel Sandwich Board

1. Brief introduction of products
Inorganic uninflammable color steel sandwich panel is a novel material composed of inorganic plate and rock wool plate, which are compounded with highly intense compounding agent by heating and compressing with special technologies.
Compared with rock wool plate, the inorganic uninflammable color steel sandwich panel  is characterized by good surface flatness, compression strength, and high fire-resistant performance; also, it has the performances of heat preservation, heat insulation, sound insulation, moisture-proof, seismic protection, etc. Compared with gypsum color steel plate, it is characterized by light weight, easy installation and construction, etc. According to the tests conducted by the National Fire-fighting Equipment Quality Supervision and Testing Center, the product is completely in line with the fire protection criteria of the national fire protection authorities.
