Section 1: Material and Cost Savings

A significant advantage of closed-form deck panels is that they can save temporary molds, thereby reducing overall or partial formwork support. This reduces the demand for molds and related costs. Moreover, as closed-form deck panels can serve as tension-reinforcing steel, they can minimize the fabrication and installation work for steel, further saving costs.

Enhance structural strength

The section centroid distance of the closed steel deck is closer to the bottom of the deck than that of the open or tapered steel deck sections. This means that when analyzing the bearing capacity of the composite steel deck based on the plasticity theory, the internal force arm of the concrete's pressure center and tension center is larger, fully utilizing the material's strength. Consequently, the closed composite steel deck exhibits greater internal forces. This allows the closed steel deck to maintain high stability even under heavy loads.

Four: Excellent fire-resistant properties

Another advantage of the closed-joist deck is its fire-resistant properties. It can completely replace the tensile strength steel on the joist deck, achieving fire resistance without the need for fire-retardant paint.Two-hour fire resistance. This significantly enhances the building's fire protection capabilities and reduces fire risks.

Five: Excellent load-bearing performance

The embossed corner design of the closed form deck enhances the gripping power of concrete on the deck, resulting in a truly combined effect when combined. This means that closed form decks can better bear and distribute the loads of buildings, improving the overall stability of structures.
