Rebar Steel

Since concrete is very weak in tension but strong in compression, steel reinforcement bars, also known as rebars, are used to increase the tensile strength of the material. Steel is only used as a rebar because its thermal expansion coefficient is nearly equal to that of concrete. At Relgrow, we supply high-quality rebar steel for strong foundations.

Light Gauge Steel

Light-gauge steel is a cold-formed material used to strengthen and streamline construction processes. It doesn't age as wood does. Contrary to structural steel, it is not hefty. It is not as weighty as concrete. Low construction waste production from low gauge steel also benefits the environment through reduced CO2 emissions, reduced freshwater use, and increased steel component recycling.

Structural Steel

Structural steel is used to create construction materials in a variety of shapes. Many shapes made of structural steel have an elongated beam with a particular cross-section profile. This type of steel lay the foundation of any architectural structure. Relgrow supplies high-in-quality steel for all construction needs.

Mild Steel

Low carbon steel includes mild steel as a subtype. Metals called carbon steels or mild steels, with a maximum carbon content of 2.1 per cent, improve the properties of pure iron. Due to its unmatched weldability and machinability, usage has increased dramatically in the construction industry.

Stainless Steel

As an alloying component, chromium makes up 10–20 per cent of the composition of stainless steels, along with other elements like nickel, silicon, manganese, and carbon. These steels are safe to use in exterior construction because of their increased ability to withstand bad weather and have remarkable high corrosion resistance.

Alloy Steel

By including additional alloying elements like nickel, copper, chromium, and/or aluminium, alloy steels are produced. These additions improve the steel's machinability, corrosion resistance, ductility, and strength in strong buildings.

Tool Steel

Tool steels are excellent in cutting and drilling equipment. The combination of tungsten, molybdenum, cobalt, and vanadium boosts their heat resistance and all-around toughness. They are also the preferred material for the majority of hand tools because they maintain their shape even under heavy use.

High Durability and Flexibility

Due to its durability and flexibility, structural steel is frequently the preferred material used by architects and builders when designing structures.


Susceptible to Corrosion

Iron is a component of steel. It is therefore vulnerable to corrosion. It requires painting to make it corrosion-resistant, which raises the cost of maintenance.

Guidelines to buy Steel for construction

When planning to purchase steel bars, one needs to conduct adequate research. The steel bars are crucial to the structural system's longevity. Check all quality marks before quoting for constructional steel bars.


Thermo Mechanical Treatment, or TMT, is a distinctive metallurgical process used to produce TMT steel bars. The Bureau of Indian Standards has approved these TMT bars for use in building and construction projects. Relgrow delivers these TMT steel bars to its clients for all construction work.

TMT steel bars come in a variety of grades, where grade denotes the quantity of stresses applied to cause deformation. The main types are as follows:

  • Fe-550 TMT Steel Bars
  • Fe-500 TMT Steel Bars
  • Fe-415 TMT Steel Bars

The molten iron undergoes pretreatment before being transformed into steel in a basic oxygen furnace (BOF) or convertor. The BOF, which houses the molten iron from the blast furnace, is filled with oxygen. The iron's carbon is eliminated as carbon dioxide when this oxygen combines with the iron's carbon , resulting in formation of TMT bars.

TMT steel bars are available in a variety of diameters, including 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 32mm, and 36mm. In order to serve as a load bearing member for slab homes, 8mm–10mm size bars are used in slabs and stair ups.
