There are different types of steel used in the construction industry. Steel is an iron alloy composed of carbon content ranging from 0.03% to 1.075%, and often other elements. Many people get confused between Steel and iron. The difference between Steel and iron is that iron is used as the base metal to produce Steel.
One of the significant advantages of Steel is that Steel has high tensile strength and low cost. Thus it becomes an essential component for constructing buildings, infrastructure, construction tools, etc. Steel is also one of the most produced raw materials in the world, according to the data steel production value exceeds 1.3 billion tons a year.
Importance of Steel in Construction
1- Steel is relatively cheap when compared with other alternative construction materials.
2- Steel structures are fire-resistant compared to a rustic design as wood is a combustive material and is lower fire-resistant when determined with RCC structure.
3- Working with Steel on a construction project can be pretty straightforward. Because of simple-to-make portions of a steel structure, it’s hassle-free to install and assemble them at work, and there’s no need to estimate and cut off corridor hard.
4- Steel structures can repel outside weights, for example, earthquakes and cyclones providing much safety and stability.
Best Types of Steel Used in Construction
1- Rebar Steel
Steel rebar, often known as reinforcing or fortifying Steel, is used as a strain device in reinforced concrete or masonry structures. Rebar steel can hold the structure together even under enormous pressure. Rebar steel is available in various yield strengths, necessary elasticity, chemical composition, and elongation percentage parameters.
Types of Rebar Steel
- Plain steel wire for concrete reinforcement.
- Epoxy-coated steel bars for welded deformed Steel.
- Plain bars and rail steel deformed bars.
- TMT steel bars.
- Stainless Steel.
- Low-alloy steel.
- Axel steel.
- Low carbon steel bars.
2- Structural Steel
Structural Steel is a category of Steel that is used as a construction material for making structural steel shapes. A structural steel shape is a profile that is formed with a specific cross-section and follows certain standards for chemical composition and mechanical properties. One advantage of structural steel is that it is very ductile, sturdy, and durable. Structural steel can be molded in almost any shape, depending on the construction.
Structural steel shapes, sizes, composition, strengths, storage practices, etc., are regulated by standards in most industrialized countries.
3- Mild Steel
Mild Steel, also known as MS, is the most prevalent Steel used in the construction industry. It’s incalculably strong and long-lasting. Mild Steel helps in making a solid foundation for any type of structure.
Mild Steel is beneficial in construction because of its strength. It does not break when bent and is exceptionally flexible and malleable. Mild Steel also has high plasticity and can withstand natural disasters such as earthquakes without generating cracks in the Steel which provides extra safety to the structures.
4- Alloy Steel
Alloy steel is divided into two types “High Alloy Steel” and “Low Alloy Steel.” High alloy steel is used to hold liquids, mining materials, chemicals, and pharmaceutical equipment. In contrast, Low alloy steel is suitable for various applications, including seamless rolling ring forging and studying outlets.
Major advantages of alloy steel are its hardenability, reduced grain growth, excellent temperature resistance, and a cheaper steel building alternative.
5- Carbon Steel
Carbon steel is made up of carbon, manganese, silicon, and sulfur and phosphorus impurities. Carbon steel’s strength and elasticity are determined by the amount of carbon present in the alloy. When the carbon concentration increases, the Steel gets very much harder and stronger. Carbon steel has numerous benefits such as being available in a variety of forms to meet the needs of different project types and having a high resistance to corrosion, scaling, heat, and fire.
Types of Carbon Steel
- Low Carbon
- High Carbon
- Medium Carbon
6- Light Gauge Steel
Light gauge steels are made up of thin sheets that adhere to strict specifications. A very basic example of light gauge steel is the Light gauge steel joists, both are widely accessible in hardware stores, and they are both flexible and safe.
For the development of modern civilization, Steel has played a vital role. Steel is a viable and cost-effective alternative to other construction materials. Advantage of using steel as a construction material is that it provides safety, sustainability, and stability to the structure. A contractor should always understand the different types of steel used in construction and should choose them according to the nature of their project.
