Open-Type Steel Deck

The YX51-305-915 Open-Type Steel Deck is a professionally engineered structural profile designed for composite floor systems in modern multi-story construction. As a common and widely adopted type of floor decking, it serves as permanent formwork for concrete slabs, combining structural efficiency with practical functionality. The profile’s specifications define its key characteristics: a ​51mm rib height​ provides considerable depth for embedding concrete, enhancing composite action and load-bearing capacity; a ​305mm pitch​ ensures uniform distribution of strength across the deck; and an ​effective coverage width of 915mm​ optimizes installation speed while minimizing material overlaps.

A distinctive feature of this deck is its ​open-type design, which allows easy integration of electrical conduits, communication cables, and HVAC components within the rib cavities. This significantly simplifies MEP (mechanical, electrical, and plumbing) installations and reduces overall construction time. The deck is fabricated from high-strength steel, with a standard ​coil feed width of 1150mm​ before roll-forming, ensuring consistency in production and performance.

Ideal for commercial buildings, industrial facilities, and high-rise projects, the YX51-305-915 supports large spans between beams or joists, reducing the need for intermediate supports. Its open-rib configuration also promotes better concrete consolidation and provides visual assurance during pouring and inspection. When combined with concrete, the system acts as tensile reinforcement, resulting in a lightweight yet robust floor assembly capable of handling heavy dynamic loads.
