Within the last few decades, due to the development of high-rise buildings, the steel-concrete composite floor system(composite steel floor decking) has been increasingly popular.

steel composite floor deckingPeople roll form steel floor decking  typically from Galvanized steel of 0.8-1.5mm thickness and 1250mm width. Steel composite floor usually has a ribbed steel decking with embossments designed to interlock with concrete slabs, creating a reinforced concrete slab that serves the dual purpose of a permanent form and positive reinforcement.

A composite floor decking consists of a reinforced concrete floor slab and structural steel floor beams acting compositely together. The composite steel floor system is ideal for high-rise building construction, due to the tensile strength of steel and the compressive strength of concrete. The international contractors prefer to installing such floor as part of a compoiste flooring system. However, in China, the seel decking acts just as permanent formwork to the concrete.

Actually, people always use the steel floor decking to create a composite structure with the concrete slab poured upon it. The decking rests over the structural steel floor beams network, and contractors can install that by suitable means.  In addition, steel floor decking is a versatile and sustainable flooring solution widely acknowledged to minimise onsite construction duration’s.

When you have the chance to view the metal deck in action, you can see different steel decking profiles applied! The determining factors for selecting the proper ones are the depth of the slab, weight of the concrete (normal weight or lightweight), the support spacing and the uniform load you are trying to support.

Composite steel decking construction has contributed significantly to the dominace of steel frames in the commercial building sector.

Compared to the traditional reinforced concrete flooring system, there are many benefits that composite steel flooring decking system would bring.

Greater Durability of Composite Steel Floor Decking System

It’s available to make different steel decking profiles for inhibitting any longitudinal slip between the steel and concrete in the slab itself, and any transverse movement between the slab and the supporting beams.

Easy and Safe Construction of Steel Floor Decking

We can easily crane these bundles into specific work areas, and the individual sheets quickly laid by hand. Cable trays and pipes can be hung from the underside of the steel decking by attaching to special ‘dovetail’ recesses. During construction, the decking provides other benefits, like acting as a working platform for storage of materials.

Quick Installation of Steel Floor Decking

Contractors lift bndles of decking into place on the structure, for distribution by hand. No need to use a large numbers of crane lifts, when compared with the precast alternative. The ability to stack the pieces of decking into bundles also reduces transport time and costs. When appropriately orientated and fixed to the steel beams it can restrain them against lateral torsional buckling.

Cost Reduction of Composite Steel Floor Decking System

Consequently, this means a lighter, smaller structure and less waste.  Besides, this composite steel floor decking system has also dramatically reduced the labour costs, since props are no need.

More Flexible Design of Steel Floor Decking

With the diferent designs for metal floor deck roll forming machines, we can manufacture varied steel floor decking that gives more strength, flexibility and efficiency, based on many practical cases and a multitude of solutions.

In addition to these advantages, we have some no less important benefits!For example, easier construction, the non-contamination of other materials, easier stockpiling and cleaning, safe formwork and platform on which to work, the bracing of the structure and the ease with which to install the facilities, among others.
