Steel metal primarily, is a carbon steel that is a combination of iron and carbon. There are types of steel that are used to in a form, decoratively used for ironwork such as, railings and gates. Medium carbon steel is used for structural steelwork and high carbon steel is used for manufacturing tools as-well as high-strength wires.
The uses of steel in the construction industry are to build high rise buildings, structural steel that is resistant to external forces against climates of winds and earthquakes.
Steel is an important material used in engineering and construction. Believe it or not, it is very much used in every aspect of our lives, from cars, to refrigerators and washing machines. Not only this but steel can be recycled over and over again improving the environment without loss of property.
Steel is a popular material that is used in buildings due to its flexibility and les time consuming when constructing. It cannot be compared to the use of wood and concrete, as companies would suggest. It is also at an advantage compared to other materials as it is more cost-efficient.
Structural steel is made from steel in which is carved out of precise cross-sections, yet still following the standards when it comes to chemical composition and mechanical properties.
Structural steel is commonly known to be flexible, strong and very durable yet it is very resistant and are not costly compared to your typical used materials. It can be transformed into any shape depending on its steel construction type, as well as the country where steel specification is unique.
Structural steel types are categorized by their shapes and properties in which is used for different construction.
Angled Section – Comes in equal and unequal sections, both right angled however the unequal section differs. As it has different axis’, making then L-shaped. These sections are very strong and durable including strength and weight ratio. It is commonly used in infrastructure, residential construction, mining and much more.
Circular Hollow Section – Tubular cross sections, have higher resistance to torsion. The wall is thick all round making the shape of the steel ideal for loading applications.
Flat Section – Often referred to as plates, known to be the most versatile steel section in construction. They have to be attached to another section which makes it a strengthening tool.
Parallel Flange Channels – Known as U-shaped channeled beams, they have right angled corners in which come in different sizes. The two sizes are parallel flange channels which are always the same length. They are high in strength to weight ratio.
Rectangular Hollow Section – Similar to circular hollow sections making the difference rectangular cross section. Their flat surface makes them fabricated. This includes, mechanical and construction steel application.
Tapered Flange Beams – These are available in different sizes also, commonly used for cross-section of girdens. They have high resistance however, usually when pressure is applied to the length, they tend to twist.
Universal Beams – Known as I-beams and H-beams, they are flatly shaped, like their name. I-beams stand upright and H-beams stand on its side. They are commonly used in civil engineering and construction as well as other industries.
Universal Column – Similar to universal beams, columns are used mostly used for structural purposes. They have load-bearing capabilities.
Rebar steel is known as a reinforcing steel. It is commonly used as a tension mechanism to help hold concrete and other structure in place. It is also available in various types of grades and specs within strength, yield strength chemical composition as well as elongation percentage.
It provides durability, stiffness and resistance in which spreads through a wider area that other types of steel in construction are not equipped to do.
Mild steel is a very popular use of steel, commonly knows as plain carbon steel used in construction of buildings. This type of steel contains between 0.12% and 2% of carbon and this is the main alloying constituent. The original purpose of carbon is the hardening when steel-making, the greater level of carbon, the harder and stronger the steel becomes and lower the melting point.
Its popular material is used due to its low’ price and versatility across many applications. When large quantities of steel are needed, mild steel is the go-to. Similarly, to structural steel, mild steel frame acts in accordance, it is very flexible and does not crack when force is given. It strongly supports its common usage.
Stainless steel is very commonly used in construction industries, this is due to their properties. They have such a high resistance to corrosion; their high and low temperatures and majority of stainless steel can easily be fabricated. It is used to provide support and strength to structure, its style is suitable to various ranges of surface finishes in which are easy to maintain.
Stainless steel is not only restricted to the use for buildings it is also used in many other popular applications such as:
- Architectural cladding
- Drainage and water systems
- Wall support products
These steels are becoming the grand popularity and in fact is beginning to take over the construction industry due to its properties of durability and flexibility.
