Foam color steel plate is an organic material, it has the characteristics of thermal insulation, light weight and easy installation. It has been widely used in recent years. One of the disadvantages is that the foam color steel plate is extremely easy
to burn and can not meet the national fire protection requirements.
Rockwool coloured steel sheet is a new type of fire-proof sheet with the strongest fire resistance in the coloured steel sheet series. It is made of natural rocks, blast furnace slag, etc. which are melted into wires at high temperature and then solidified. Rockwool coloured steel sheet meets the requirements of secondary fire protection of clean workshop, and is the most ideal decorative plate for indoor ceiling and movable room construction. It has the fire resistance of 600 C and the fire resistance grade reaches A. Polystyrene and polyurethane are not comparable. Its core material is non-combustible rock wool.
Polyurethane sandwich board is composed of upper and lower color steel plate and middle foamed polyurethane. It is one of the widely used building materials in the current construction industry. It has good thermal insulation, heat insulation and sound insulation effect. Polyurethane with fire retardant material does not support combustion.
Glass wool and phenolic foam sandwich color steel plate are slightly more expensive than foam steel. Phenolic foam is a polymer rigid rigid aluminum foil foam product, which is made from thermosetting phenolic resin. It has the characteristics of light weight, fireproof, non-burning in open fire, smokeless, non-toxic, non-dripping, wide temperature range (-196~200 C), non-shrinkage and non-embrittlement in low temperature environment.
