Strong concrete holding and wrapping shear resistance: the special closed rib design has strong longitudinal shear resistance. Under its excellent allowable design load, the steel bearing plate has not slipped from the concrete.

佳品的性能稳定性能：板肋全部在包裹在混凝土里面，形同现浇混凝土板里面的钢筋。闭口楼承板能够全部替代楼板中正弯矩受拉钢筋而且无须喷刷性能稳定涂料即可达到1.5小时的耐火时效。

Performance stability of the best product: all the slab ribs are wrapped in the concrete, which is similar to the reinforcement in the cast-in-situ concrete slab. The closed floor bearing plate can completely replace the positive moment tensile reinforcement in the floor slab, and the fire-resistant aging of 1.5 hours can be achieved without spraying stable coating.

优越的组合楼板断面：闭口组合楼板有大的的楼板效果优良高度，使用阶段提供较大的正弯矩抵抗能力。

Superior composite floor section: the closed composite floor has large floor effect and excellent height, and provides large positive moment resistance in use stage.

板底卡槽悬吊系统：可供天花、吊顶，水电管等的安装使用，不需要钻孔，电焊，在建筑物使用期间，可依需要任由移动、拆除或重新安装。施工方便、速度适宜：端部不需要任何堵头，无漏浆现象，可缩短施工周期。

Card slot suspension system at the bottom of the board: it can be used for the installation of ceiling, ceiling, water and electricity pipe, without drilling and welding. During the use of the building, it can be moved, removed or reinstalled as needed. The construction is convenient and the speed is appropriate: the end does not need any plug, there is no slurry leakage, and the construction cycle can be shortened.

平整的板底外观：楼板底面平整，对不希望吊顶的建筑物来讲，比较美观。

Flat bottom appearance: the floor bottom is flat, which is more beautiful for buildings that do not want ceiling.

可效果优良地降低楼板高度：根据性能稳定规定和防振颤，闭口楼承板总厚度只有110-130毫米，减轻重量、降低成本、增加净高。

It can effectively reduce the floor height: according to the performance stability regulations and anti vibration, the total thickness of closed floor bearing plate is only 110-130 mm, reducing weight, reducing cost and increasing net height.

成本低：闭口楼承板底部承受正弯矩的钢筋由闭口型压型钢板替代，无须喷性能稳定涂料，减少钢筋用量、降低成本。

Low cost: the reinforcement bearing the positive bending moment at the bottom of the closed floor bearing plate is replaced by the closed profiled steel plate without spraying performance stable coating, so as to reduce the amount of reinforcement and reduce the cost.
