THE USE OF STEEL IN THE CONSTRUCTION INDUSTRY
Construction Industry
The construction industry is one of the most important steel-using industries, accounting for more than 50% of the world’s steel demand. Steel is needed to support everything from houses to parking lots, schools to skyscrapers. Additionally, steel is also used for the cladding of roofs and facades.
According to a new UN report released in 2019, the world population is expected to increase by 2 billion people over the next 30 years, from 7.7 billion today to 9.7 billion in 2050. This will be accompanied by rapid urbanization. As the global demand for buildings and infrastructure continues to grow, reducing natural resource consumption and associated emissions is critical to future sustainability.
How steel is used in construction and infrastructure?
The possibilities for using steel in buildings and infrastructure are endless, the most common applications are listed below.
1) For buildings
the building.
exterior wall insulation.
construction. The reason for using steel is that it adheres well to concrete, has a similar coefficient of thermal expansion, and is strong and relatively cost-effective. Reinforced concrete is also used to provide deep foundations and is currently the main building material in the world.
equipment and internal plumbing.
2) For infrastructure
the distribution of water to and from the house, and the distribution of gas. The rest are mainly rebars for power stations and pump houses.
ports, and airports requires steel. In this application, approximately 60% of the steel is used as reinforcement, with the remainder being profiles, plates, and rails.
