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.

佳品的性能穩定性能：板肋全部在包裹在混凝土里面，形同現澆混凝土板里面的鋼筋。閉口樓承板能夠全部替代樓板中正彎矩受拉鋼筋而且無須噴刷性能穩定涂料即可達到1.5小時的耐火時效。

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.

優越的組合樓板斷面：閉口組合樓板有大的的樓板效果優良高度，使用階段提供較大的正彎矩抵抗能力。

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

板底卡槽懸吊系統：可供天花、吊頂，水電管等的安裝使用，不需要鉆孔，電焊，在建筑物使用期間，可依需要任由移動、拆除或重新安裝。施工方便、速度適宜：端部不需要明顯堵頭，無漏漿現象，可縮短施工周期。

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.

平整的板底外觀：樓板底面平整，對不希望吊頂的建筑物來講，比較美觀。

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

可效果優良地降低樓板高度：根據性能穩定規定和防振顫，閉口樓承板總厚度只有110-130毫米，減輕重量、降低成本、增加凈高。

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：閉口樓承板底部承受正彎矩的鋼筋由閉口型壓型鋼板替代，無須噴性能穩定涂料，減少鋼筋用量、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.
