Rock Wool Sandwich Wall Panel

Specifications:* Length: Customized* Effective width Wall panel: 950mm* Materials: Color steel sheet  and Rock Wool board* Structure: Upper and lower layer: Color steel sheet; Middle: Rock Wool board* Thickness: Color steel sheet: 0.3-0.8mm ; Polyurethane board: 50mm 75mm 100mm* Polystyrene density: 40-90kg/m3* Conventional color: Red,Website:http://www.lq-steel-structure.com, white, blue, silver.* Lifetime: 20~35 years* Characteristic: Low cost , litter heavier, Fireproof, soundproof, retardant,  heat insulation, water resistant, environmental ,easy to install* Application: Various walls referring to the large size factory buildings, storages, exhibition halls, gymnasiums etc.Features:* Stiffness: As core material and two layers of steel wool into a cohesive whole, to work together, plus surface-pressure wave from the roof, the overall stiffness far better than the pressure plate folder wool (fiberglass cotton) field composite sheet. Sandwich through the connecting members and purlins fixed, greatly improving the overall stiffness of the roof, the roof strengthened overall work performance. Selection wool sandwich panels, purlin distance can be larger, it can save purlin dosage of 1/3 to 2/3.* Fastening reasonable way: rock wool roof using snap connections, avoiding the leaking roof seams risks, the amount of savings accessories.* 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 at the peak position on the roof surface, and using a special waterproof construction, waterproof to avoid weak points.* The installation period is short: rock wool sandwich panel, because the field no secondary processing, not only to keep the surroundings clean and tidy, does not affect the normal running of other processes, and can greatly shorten the installation cycle sheet, rock wool sandwich panel the daily average of 600 to 800 square meters installation area.* Anti-scratch protection: rock wool sandwich panel production, can be pasted polyethylene adhesive protective film on the surface, in order to avoid the transportation and installation of the steel surface coating process by scratches or wear.* Rock wool sandwich panels with vertical filament fiber wool core material to make the surface color plates, even by automated virtual machine, after the pressure-type high-strength adhesive bonded. Since the color plate and core material are non-combustible mineral wool body, so its excellent fire performance, non-flammable: A grade (refractory temperature 650 ℃), refractory limit: 120 minutes (thickness 80mm)
