Specification :

Rock sandwich panel is shaped by rock wool and steel panel through automatic production line without further jointing at the site, it has good properities of heat preservation and sound insulation, heat insulation, fireproof.

Usage: widely used for the roof, exterior walls and internal partitions of industrial and civil buildings which have requirements of fire, sound insulation and thermal insulation , especially for the fire controlling projects.

Constructure
1) The upper and lower surfaces: adopted by galvanized color steel plate, thickness 0.4-0.8mm. According to customer' s specific need, it also can be used Galvanized color steel plate or aluminum plate. After rolling by the mould machinery the steel plate is stuck with the rock wool.
2) Rock wool core material: The density of rock wool block is 120kg/ m3, it is staggered and rolled out with its fiber direction perpendicular to the upper and lower surface of the sandwich panel, the rock wool is closely-phase jointed filling the entire vertical and horizontal section of the sandwich panel. The rock wool between the blocks and steel sheet is shaped into one whole block by high-intensity foam, sophisticated process ensures high-density rock wool insulation between the inner body and metal plate can produce a very strong adhesion, which made rock wool sandwich panel has a strong stiffness.
