The standard mezzanine framing system comprises steel deck supported by joists into main mezzanine beams. If necessary due to design loads, intermediate columns also support the main beams. The top flange of the joists aligns with the top flange of the primary beams.
Embossments on the top and sides of the deck sheet ribs enhance grip and minimize slip by forming a bond with concrete, akin to normal reinforcement. This setup offers permanent formwork and positive reinforcement. Unlike conventional concrete slab construction, there's no need for erecting, removing, handling, or storing timber/steel formwork, thereby saving valuable time. The ribbed underside (soft fit) presents a clean, uniform, and aesthetically pleasing appearance, reducing the cost of ceiling finishes. MS deck sheet is provided to support suitable floor loads and is covered with formed concrete.
