1. Good rigidity: because the rock wool core material and two layers of steel plates can be bonded into a whole to work together, and then the wave forming on the upper surface of the roof panel is added, its overall rigidity is much better than the on-site composite plate with rock wool (glass wool) sandwiched in the profiled plate.

夹芯板，在通过连接件还有檩条固定后，能够大大的提高屋面的整体钢度，并且加强屋面整体工作性能。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。

The sandwich panel can greatly improve the overall rigidity of the roof and strengthen the overall working performance of the roof after it is fixed through connectors and purlins. Rock wool sandwich board is selected, and large purlin distance can be adopted, so 1 / 3 ~ 2 / 3 purlin consumption can be saved.

2、扣接方式合理：岩棉屋面板采用扣接连接方式，避免了屋面板接缝漏水的隐患，节省了配件用量。

2. Reasonable buckle connection mode: the rock wool roof panel adopts buckle connection mode, which avoids the hidden danger of water leakage at the roof panel joint and saves the amount of accessories.

3、固定方法牢固合理：岩棉屋面板采用特制M6自攻螺丝与檩条固定，能有效抵抗台风等外力作用。自攻螺丝设置在屋面板上表面的波峰位置，并采用特殊的防水

3. The fixing method is firm and reasonable: the rock wool roof panel is fixed with special M6 self tapping screws and purlins, which can effectively resist external forces such as typhoon. The self tapping screw is set at the wave crest on the upper surface of the roof panel and adopts special waterproof

构造，避免产生防水薄弱点。

Construction to avoid water-proof weakness.

4、安装周期短：岩棉夹芯板，由于现场无需二次加工，不仅可保持周围环境的整洁，不影响其他工序的正常进行，而且可以大大缩短板材的安装周期，岩棉夹芯

4. Short installation cycle: the rock wool sandwich board can not only keep the surrounding environment clean and tidy without affecting the normal progress of other processes, but also greatly shorten the installation cycle of the board

板的日平均安装面积达600~800㎡。

The average daily installation area of the board is 600 ~ 800 m2.

5、防划伤保护：岩棉夹芯板生产时，可在表面粘贴聚乙烯不干胶保护膜，以避免运输及安装过程钢板表面涂层受到划伤或磨损。

5. Scratch protection: during the production of rock wool sandwich board, polyethylene self-adhesive protective film can be pasted on the surface to avoid scratch or wear on the surface coating of steel plate during transportation and installation.
