1, stiffness: As the core material with two layers of steel wool into a cohesive whole, working together, plus the roof surface from the pressure wave type, the overall stiffness far better than rock wool clip pressure plate (glass cotton) live composite sheet. Sandwich through the connecting members and purlins fixed, greatly improving the overall stiffness of the roof, the roof strengthened overall performance. Selection of rock wool sandwich panel, may be larger purlin distance, it can save purlin dosage of 1/3 to 2/3.

2, fastening reasonable way: using rockwool roof fastening connection, avoiding the risk of leaking roof seams, saving the amount of accessories.

3, fixed firmly reasonable method: rockwool roof using a special self-tapping screws M6 with 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.

4, short installation period: rock wool sandwich panel, since the site no secondary processing, not only to keep clean surroundings, does not affect the normal running of other processes, and can greatly shorten the installation cycle sheet, rock wool sandwich panels daily average of 600 to 800 square meters area of the installation.

5, anti-scratch protection: rock wool sandwich panel production, can be attached to the surface of a polyethylene adhesive protective film to prevent the transport and installation of the steel sheet surface coating process being scratched or worn.
