Sealing performance: The rock wool sandwich board adopts an assembly line production process, which utilizes the excellent waterproof performance of polyurethane products to overcome the disadvantage of easy water absorption and deliquescence of rock wool, effectively extending the product's service life in terms of physical properties.

剛度好：它材與兩層鋼板粘接成一個整體，共同工作，再加上屋面板上表面起波壓型，其整體剛度遠勝于壓型板夾巖棉（玻璃絲棉）的現場復合板材。夾芯板通過連接件與檁條固定后，大大提高了屋面的整體剛度，加強了屋面整體工作性能。選用巖棉夾芯板，可采用較大檁距，故可節省檁條用量1/3～2/3。

Good stiffness: Its material is bonded with two layers of steel plates to form a whole, working together. In addition, the surface of the roof panel is corrugated and shaped, and its overall stiffness is much better than the on-site composite plate with rock wool (glass wool) sandwiched on the profiled plate. After being fixed with purlins through connectors, the sandwich panel greatly improves the overall stiffness of the roof and enhances its overall working performance. Selecting rock wool sandwich panels can use larger purlin spacing, thus saving 1/3 to 2/3 of the purlin usage.

扣接方式合理：采用暗扣連接方式，避免屋面板接縫漏水的隱患，節省配件用量。采用M6自攻螺絲與檁條固定，有效抵抗臺風等外力作用。攻螺絲設置在屋面板兩板接縫之間的波峰位置，采用防水構造，避免產生防水薄弱點。

Reasonable buckle connection method: use concealed buckle connection method to avoid the hidden danger of water leakage at the joints of the roof panel and save the amount of accessories. Fix with M6 self tapping screws and purlins to effectively resist external forces such as typhoons. The tapping screw is set at the peak position between the joints of the two roof panels, using a waterproof structure to avoid the occurrence of waterproof thin spots.

安裝周期短：由于現場無須二次加工，不僅保持周圍環境的整潔，不影響其它工序正常進行，而且縮短板材的安裝周期，巖棉夾芯板的日平均安裝面積達600～800m2。

Short installation cycle: As there is no need for secondary processing on site, it not only keeps the surrounding environment clean and does not affect the normal operation of other processes, but also shortens the installation cycle of the board. The average daily installation area of the rock wool sandwich board is 600-800m2.

防劃傷保護：在生產時，可在表面粘貼聚乙烯不干膠保護膜，以避免運輸及安裝過程鋼板表面涂層受到劃傷或磨損。

Anti scratch protection: During production, polyethylene adhesive protective film can be pasted on the surface to avoid scratches or wear on the surface coating of the steel plate during transportation and installation.
