What is Mild Steel? – Mild steel is a term used for general steel. Specifically, it is a carbon steel that consists of a low amount of carbon. Therefore, another name for mild steel is “low carbon steel.” The amount of carbon found in is different from other carbon steel that typically has a content of 0.30% to 2.0%.
- In mild steel, it has approximately 0.05% to 0.25% steel.
- Unlike aluminium, stainless steel, and brass, mild steel is not an alloy steel.
- An alloy steel contains big amounts of other elements.
- Mild steel contains amounts of chromium, molybdenum, iron, and other elements, but not in large amounts.
- Because mild steel has less carbon, it’s more machinable, weldable and ductile than other steels.
However, it is not as strong as high carbon and alloy steels, and it is magnetic. If mild steel is not coated correctly, it is subject to oxidation, otherwise known as rust. However, like stainless steel, it’s more affordable than other steels. Mild steel can be seen in various uses such as in decorations, automobiles and furniture.
In construction, you can find mild steel used in signs, building structures, wires, fencing and nails. As explained, common metals in the construction industry are widely used because they are durable, resistance to weather, and sturdy. They also provide a clean look and a beauty that is set apart from other construction materials.
There are a wide variety of metals used in construction, but aluminium, stainless steel, copper, brass, and mild steel are some of the most common. Of the metals discussed in this article, buildings are rarely constructed without the use of aluminium.
- Architects and designers find aluminium to be one of of their most favourite metals.
- Stainless steel is the most recycled metal on Earth and those involved in construction like it, especially for its low price.
- Copper, one of the oldest metals, is extremely versatile and a favourite for engineering materials.
It’s durable, corrosion resistance, and is suitable for a wide range of projects. Brass is not only a useful metal used for construction, but it is known for its attractive gold appearance. Finally, mild steel is one of the more affordable metals that has lots of uses in construction.

Which steel is best for construction?
Fe 500 grade is the standard choice of TMT steel bars recommended by us for house constructions and commercial buildings, Fe550 for bridges and other large construction, and Fe 600 for big industrial projects. Based on the size and nature of construction requirements, you can choose from different grades of TMT steel bars as all TMT steel bars are best for construction.
TMT steel bars or Thermo Mechanically Treated bars are the best for house construction due to high tensile to yield strength, ductility, weldability, lightweight, corrosion & fire resistance, etc.
TMT bars are Thermo Mechanically Treated bars mainly used for civil constructions purposes. TMX steel is a High-quality TMT bar. Thermax technology is used in the manufacturing process of these bars.TMX bars are used for high-end TMT bar requirements. From the cost point of view, TMT bars are most preferred by constructors.
Thermo Mechanically treated bars or TMT bars are the best quality steels for any construction purposes
Kairali TMT offers the best quality TMT steel bars for construction in Kerala with a legacy of over 125 years in manufacturing and distributing steel bars all over South India.
The sizes of TMT bars used for stair-ups and slabs are usually 8mm-10mm size bars. For beams and columns, 12mm-25mm size bars are used. Other large-sized constructions such as dams and bridges require 32mm-36mm size bars.
Fe500 and Fe500D TMT bars are both the best TMT steel bars for construction projects. The tensile strength of Fe500 and Fe500D remains the same. But, Fe500D TMT bars have greater ductile strength compared to Fe500 TMT bars, making it more preferable where ductility is a primary factor of consideration.
