Rock wool sandwich panel have the characteristics: 1, good stiffness: As core material and two layers of steel wool into a cohesive whole, to work together on the plus roof surface waves from pressure-type color steel sandwich panel manufacturers, The overall stiffness far better than rock wool clip pressure plate (glass cotton) live composite sheet. Sandwich through the connecting members and purlins fixed sandwich panels, greatly improving the overall stiffness of the roof, the roof strengthened overall work performance. Rock wool sandwich panels sandwich selection enclosure, purlin distance can be larger, it can save purlin dosage of 1/3 to 2 / 3.2, Snap reasonable manner: rockwool roof using snap connection avoid the leaking roof seams risks, the amount of saving accessories. 3, and fixed firmly reasonable: Rockwool roof using a special self-tapping screws M6 and purlins fixed, can effectively resist typhoons and other external forces. Self-tapping screws provided on the roof peak position steel sandwich panel brand surface and using a special waterproof construction, waterproof to avoid weak points. Rock wool sandwich structure: 1) The upper and lower surface: galvanized color steel, thickness of 0.4-0.8mm. According to the specific requirements of customers, but also can color galvanized steel or galvanized steel. After the first steel roll forming machine composite rock wool factory. 2) rock wool core material: the density of 120kg / m3 rockwool block interleaving laying its fiber direction perpendicular to the sandwich, the lower surface, and closely connected to enrich the entire vertical and horizontal surfaces of sandwich panels. And wool and, through high-strength adhesive foaming agent between the lower plate is formed integrally between rockwool block, sophisticated production process to ensure produce extremely high density rockwool insulation between the body and the metal plate inside wall strong adhesion, so that the rock wool sandwich panel has a good stiffness.
