Punched Rock Wool Sandwich Panel: Addressing the characteristic of easy heat conduction at the joints of rock wool sandwich panels in drying chambers of the surface treatment industry, while maintaining the original performance of rock wool sandwich panels, we have independently designed and produced rock wool sandwich panels with edge-sealed steel strips and punched thermal bridge holes. 【Product Specifications】: Effective width: 1150mm, 950mm; Thickness: 50mm, 75mm, 100mm, 120mm, 125mm, 150mm; 【Material Selection】: 1. Upper/lower surface: color-coated plate/galvanized plate/stainless steel plate with a thickness of 0.4~1.0mm; 2. Core material: rock wool with a density of 120kg/m3; 3. Side steel strip: galvanized plate with a thickness of 0.5~0.8mm, punched with thermal bridge holes; 【Product Features】: 1. Smooth surface and superior appearance quality; 2. Easy installation; 3. Rock wool core material is made from natural rocks and blast furnace iron slag, melted at high temperatures into fibers and then solidified. It offers excellent sound absorption, sound insulation, and fire resistance, with a fire rating of Class A; 4. Tight joints, minimal heat conduction; when the furnace temperature is 180°C, the external plate temperature remains below ambient temperature +5°C.

Third, 950-Type Corrugated Sandwich Panel combines corrugated panels and sandwich panels into one, increasing strength threefold compared to ordinary flat color steel sandwich panels; it uses hidden self-drilling screws to connect with the roof truss, avoiding damage to exposed parts and extending the service life of the color steel sandwich panel; the panel-to-panel connection adopts a cap-type design, facilitating construction and featuring excellent water resistance.

Tongue-and-groove type effective width: 950mm; 1150mm. Thickness: 50mm–150mm; Length: unlimited.
