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.

刚度好：它材与两层钢板粘接成一个整体，共同工作，再加上屋面板上表面起波压型，其整体刚度远胜于压型板夹岩棉（玻璃丝棉）的现场复合板材。夹芯板通过连接件与檩条固定后，大大提高了屋面的整体刚度，加强了屋面整体工作性能。选用岩棉夹芯板，可采用较大檩距，故可节省檩条用量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：采用暗扣连接方式，避免屋面板接缝漏水的隐患，节省配件用量。采用M6自攻螺丝与檩条固定，有效抵抗台风等外力作用。攻螺丝设置在屋面板两板接缝之间的波峰位置，采用防水构造，避免产生防水薄弱点。

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.

安装周期短：由于现场无须二次加工，不仅保持周围环境的整洁，不影响其它工序正常进行，而且缩短板材的安装周期，岩棉夹芯板的日平均安装面积达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.

防划伤?；ぃ涸谏?，可在表面粘贴聚乙烯不干胶?；つ?，以避免运输及安装过程钢板表面涂层受到划伤或磨损。

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.
