The term “metal floor decking” refers to a form of flooring system constructed by combining concrete, steel mesh, and profiled steel sheeting with embossed patterns. Other terms for this type of flooring system include “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 fresh concrete, rebar, and construction personnel, among others. Specialized shear fasteners are utilized to enable the direct fastening of deck sheeting to the steel beam framework. In light of the aforementioned, the following highlights some of the most notable benefits of metal floor decking that should be taken into account before reaching any conclusions.
The fact that slabs constructed with metal floor decking demonstrate superior structural strength in comparison to conventional concrete slabs may be surprising. Because of the high strength-to-weight ratio that results from this, the weight can be reduced by a significant amount.
This is advantageous in the context of multistory buildings because it significantly reduces the structure’s overall weight, allowing for 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 degree of strength. Conversely, metal floor decking offers the essential reinforcement and structural strength. The deck profile itself significantly improves the capacity for tensile reinforcement, resulting in a reduction in the amount of labor and material required. The possibility of a 25% decrease in the reinforcing steel is not mentioned here. In turn, expenses would be reduced.
Concrete reinforced with metal floor decking can be used to create composite slabs, which can provide the structure with a staggering amount of strength. A robust slab that can withstand a significant amount of strain over an extended period of time can be created by combining the strength of the concrete with the malleable reinforcement of the metal floor decking.
Substantial reinforcement is not required unless explicitly indicated by the design parameters. The thickness of the slab can be reduced in order to produce lighter slabs while maintaining the same strength. Reduced foundation pressures are made possible by this, which in turn leads to less material use and, ultimately, lower costs. You now have an understanding of some of the most important benefits associated with the use of metal floor decking in Singapore.
