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.
Which steel is most used in construction?
Best Types of Steel Used in Construction Works – 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.
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.
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.
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. 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.
Low Carbon High Carbon Medium Carbon
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.

What kind of steel is used in buildings?
1. Plain Carbon Steel Or Mild Steel – This is the most common type of steel used in building construction, known as plain-carbon steel or mild steel. Its strength and durability are beyond measurement, ensuring a sturdy build. The strength that mild steel provides is extremely useful in building construction and has many advantages.
Due to the strength that mild steel provides, it is extremely useful in building construction and has many advantages. It never cracks, it’s incredibly flexible, it is ductile, and has excellent plasticity. This makes it able to endure natural disasters like earthquakes and hurricanes without significant damage.
This is by far the most significant benefit of mild steel. Other construction materials might easily collapse, break down, or catch on fire. Mild steel will not. Mild steel is low-carbon steel, meaning that it consists of,05%-.35% of carbon. This type of steel has two yield points, making it simpler to handle.
Which steel is used in RCC work?
Mild Steel Bars – This bar does not have any ribs; it comes with plain surface and in round shape. Mild Steel Bars are used in RCC for beam, slabs etc. The Tensile Strength is upto 40000 psi. Mild Steel Bars does not bond well with concrete and it is poor in quality that is why it is used in small projects with budget constraint.
What grade is normal steel?
300 Series—austenitic chromium-nickel alloys –
- Type 301—highly ductile, for formed products. Also hardens rapidly during mechanical working. Good weldability. Better wear resistance and fatigue strength than 304.
- Type 302—same corrosion resistance as 304, with slightly higher strength due to additional carbon.
- Type 303— version of 304 via addition of and, Also referred to as “A1” in accordance with,
- —the most common grade; the classic 18/8 (18% chromium, 8% nickel) stainless steel. Outside of the US it is commonly known as “A2 stainless steel”, in accordance with ISO 3506 (not to be confused with A2 tool steel). The Japanese equivalent grade of this material is SUS304.
- Type 304L—same as the 304 grade but lower carbon content to increase weldability. Is slightly weaker than 304.
- Type 304LN—same as 304L, but also nitrogen is added to obtain a much higher yield and tensile strength than 304L.
- Type 305—same as 304, but with more nickel to decrease work hardening.
- Type 308—used as the filler metal when welding 304.
- Type 309—better temperature resistance than 304, also sometimes used as filler metal when welding dissimilar steels, along with,
- — is a highly alloyed used for high temperature application. The high chromium and nickel content give the steel excellent oxidation resistance as well as high strength at high temperature. This grade is also very ductile, and has good weldability enabling its widespread usage in many applications.
- —the second most common grade (after 304); for food and uses; alloy addition of molybdenum prevents specific forms of corrosion. It is also known as marine grade stainless steel due to its increased resistance to chloride corrosion compared to type 304.316 is often used for building plants.
- —is an extra low carbon grade of 316, generally used in stainless steel watches and marine applications, as well exclusively in the fabrication of for, due to its high resistance to corrosion. Also referred to as “A4” in accordance with ISO 3506.
- Type 316Ti—variant of type 316 that includes titanium for heat resistance. It is used in flexible chimney liners.
- Type 321—similar to 304 but lower risk of due to addition of titanium. See also 347 with addition of niobium for desensitization during welding.
