Why are Steel Structures used in construction? It is an important question that we will answer in this article, as construction is one of the most important industries that use steel, as it represents more than 50% of the global steel demand, and buildings from homes to parking lots to schools and skyscrapers depend on steel for several reasons that we will talk about later, Steel is also used on roofs and as a coating for exterior walls.
Why are Steel Structures used in construction?
Steel is used in construction because of its strength, durability, and malleability, and is fire-resistant and earthquake-resistant where earthquakes are unpredictable in terms of size, frequency, duration, and location, but steel is the preferred material for design because it is inherently flexible, and bends under extreme loads rather than cracking or collapsing It is also infinitely recyclable, as when a steel frame building is demolished, its components can be reused or circulated in the steelmaking closed-loop recycling system for smelting and reuse, and steel can be recycled indefinitely Without losing its properties, about 30% of new steel today made is from recycled steel.
Fields of use of Steel Structures in buildings
The use of steel in buildings is as follows:
Structural sections: They provide a strong and rigid framework for the building and makeup 25% of steel uses in buildings.
Reinforcing bars: They add tensile strength and stiffness to concrete and makeup 44% of steel uses in buildings. Steel is used because it bonds well with concrete and has a similar thermal expansion coefficient, strong and relatively cost-effective. Reinforced concrete is also used to provide deep foundations and basements and is currently the main building material. In the world.
Panel products: 31% of it is used in panel products such as ceilings, purlins, interior walls, ceilings, cladding, and insulating panels for exterior walls.
Non-structural steel: Steel is also found in many non-structural applications in buildings such as heating and cooling equipment and indoor piping.
It is used in interior fixtures and fittings such as rails, shelves, and stairs which are also all made of steel.
Areas of use of Steel Structures in infrastructure
Where the use of steel in infrastructure is as follows:
Transportation networks: As steel is required for bridges, tunnels, railway tracks, and construction of buildings such as refueling stations, train stations, ports, and airports, about 60% of the steel is used in this application as rebar and the rest is sections, panels, and railway tracks.
Utilities (fuel, water, electricity): More than 50% of the steel used for this application is in underground pipelines for water distribution to and from housing, and gas distribution and the rest is mainly steel reinforcement for power stations and pumping houses.
