Our factory introduces the most advanced rock wool composite board production line and applies its full set of process flow and quality control system. The products produced have low thermal conductivity, high use temperature, fire prevention and non-combustibility, convenient construction, significant energy saving effect, and high cost performance. .

Rock wool insulation board has excellent fire protection, heat insulation and sound absorption performance. It is mainly used for thermal insulation of building walls and roofs; fire protection and cooling of building partitions, firewalls, fire doors and elevator shafts.

Upper and lower surface: adopt galvanized color steel plate with thickness of 0.4-0.8mm.

According to the specific requirements of customers, aluminum-plated zinc color steel plate or galvanized steel plate can be used.

The steel sheet is rolled and formed by a forming machine and then compounded in a rock wool factory.

Rock wool core material: the density is 120kg/m3;

The rock wool blocks are laid in a staggered manner, and the fiber direction is perpendicular to the upper and lower surfaces of the sandwich panel, and the entire vertical and horizontal plane of the core panel is tightly detailed.

The rock wool blocks and the rock wool and the upper and lower steel plates are connected by high-strength foaming agent to form a whole. Sophisticated production technology ensures that a strong adhesion between the high-density rock wool insulation and the inner wall of the metal plate, so that the rock wool sandwich panel has good rigidity.
