● The steel bar truss stress mode is reasonable, the material selection is economical, and the comprehensive cost advantage is obvious;
● The height of the truss and the diameter of the steel bar can be adjusted to be suitable for floor slabs with larger spans;
● It can be designed as a two-way slab.

● The mechanical properties are basically the same as those of traditional cast-in-place floor slabs, and the floor slabs have good crack resistance;
● The fire resistance is comparable to that of traditional cast-in-place floor slabs, and is superior to profiled steel sheet composite floor slabs;
● The bottom mold does not participate in the force in the use stage, and there is no need to consider fire prevention and corrosion issues.

● The amount of on-site steel bar binding work can be reduced by 60%~70%, which can further shorten the construction period;
● The truss stress mode can provide greater floor slab stiffness, which can greatly reduce or eliminate the need for temporary support.

● The steel bars are arranged evenly, and the distance between the upper and lower layers of steel bars and the thickness of the steel bar protective layer are reliably guaranteed;
● Double discount edge lap design, effectively ensuring the construction quality of the combined floor slab;
● The bi-directional stiffness of the floor slab is similar, which is beneficial to the earthquake resistance of the building;
● The welding quality of the studs is easier to ensure.
