The term “metal floor decking” refers to a flooring system consisting of concrete, a steel framework, and profiled steel sheathing with embossed patterns. Alternative terminology for this type of flooring system includes “decking floor” and “composite floor.” The standard thickness of these sheets varies from 0.75 to 1.5 millimeters, and they are galvanized on both sides to prevent corrosion. These panels are roll-formed with a wave height spanning from 50 to 75 millimeters.
In the construction industry, steel decking functions as a temporary formwork, providing support for newly poured concrete, reinforcement rods, construction workers, and various other elements. Specialized shear fasteners are utilized to enable the direct fastening of deck sheathing to the steel beam framework. In view of the preceding, the following delineates some of the most notable advantages of metal floor decking that warrant careful consideration before arriving at any conclusions.
The observation that slabs constructed with metal floor decking demonstrate increased structural strength relative to traditional concrete slabs may be unforeseen. Because of the high strength-to-weight ratio that results from this, the weight can be reduced by a significant amount.
This is beneficial in the context of multistory structures because it significantly reduces the structure’s overall weight, enabling the use of reduced foundation dimensions. Metal floor decking can reduce the amount of effort or support required for slab casting in addition to making the slabs lighter in weight.
In the case of composite slabs, the amount of concrete used in the slabs can be significantly reduced while maintaining the same strength level. Metal floor decking, on the other hand, offers the necessary structural strength and reinforcement. The deck profile significantly improves the tensile reinforcement capacity, thereby reducing the required amount of labor and material. It does not mention a 25% decrease in reinforcing steel. In turn, expenses would be reduced.
Concrete reinforced with metal floor decking can be used to create composite slabs, which can increase the building’s strength by a significant amount. A robust foundation that can withstand a significant amount of strain over an extended period of time can be constructed by combining the strength of the concrete with the flexible reinforcement of the metal floor decking.
Substantial reinforcement is not required unless explicitly indicated by the design criteria. The thickness of the slab can be reduced in order to produce lighter slabs while maintaining their strength. Reduced foundation pressures are the end result of this, as are reduced material use and costs. You now have an understanding of some of the most notable benefits associated with the use of metal floor decking in Singapore.
