Composite steel-concrete flooring systems are known as one of the most economical methods of building roofs for buildings. This system consists of composite parts of reinforced concrete floors on trapezoidal plates connected to steel beams and beams. The combined performance of the upper reinforced concrete slab and the lower trapezoidal steel sheet will play an important role in ensuring the rigidity of the roof and the optimum shear behavior. If trusses are used in these types of roofs, mechanical and electrical installations can be easily installed under the roof, so access to the installations will be possible in case of problems and possible malfunctions.

Positive features of Highest quality steel slab
Steel deck sheets fall into two categories: roof deck and ground deck. These steel sheets are used as roofing in the construction industry. Galvanized sheet was used for the first time for the roof, only as a formwork on which various types of reinforced concrete were placed. At that time, these roofs had many advantages over traditional roofs in terms of cost and project, and the only function of this steel sheet was to be transported during application and loaded before the concrete set. This group of roofing sheets is called a proof deck. Steel deck price is also cheaper than other roofs and saves consumption costs.
