We at Primegold manufacture the top-grade TMT steel Bars and are one of the best TMT steel bars suppliers in kolkata. These bars (Saria) are high-strength reinforcement bars with a rigid outer core and a soft inner core.

Recognized as a leading TMT bars manufacturer in kolkata, Primegold continues to set benchmarks for the industry. Our status as the best TMT bars supplier in kolkata is founded on our uncompromising quality, reliability, and commitment to excellence.

Our TMT bars are produced using advanced German technology and are known for their superior strength, ductility, and weldability.

Production Process

In addition to being a leading TMT bars manufacturer in kolkata, Primegold also takes pride in our commitment to sustainable construction practices. We have implemented eco-friendly production processes that reduce carbon emissions and conserve natural resources. These bars are essential and best suitable for all construction purposes in kolkata, so it is crucial to know how they are made.

  • The initial step of the production process includes passing the steel wires through a rolling factory stand. These rolled steel wires are again gone through the Tempcore water cooling process.
  • The water pressure optimizes the wires through the cooling water system. The sudden temperature change hardens the steel bar's external layer and also makes it hard and long-lasting.
  • When this cycle is completed, the TMT bars depend upon air cooling.
  • When the TMT bar chills off, it gradually becomes a ferrite-pearlite mass.

Key Steps in Quality TMT Bar Production:

Air Cooling
Self Tempering
Quenching

IMPORTANCE OF RIBS IN TMT BARS

Steel reinforcement bars (TMT Saria) are an excellent choice for today's construction projects. TMT Steel Bar has a variety of properties, including Yield Strength, Highly Ductile, Earthquake Resistance, Corrosion Resistance, and Fire Resistance. Thermex Cooling Technology is used to create high-quality TMT rods. These bars are made using two processes: curing and self tempering. As a result, the cores become ferrite and crystalline, with a martensite outer surface that is highly flexible and solid. This is not a parallel pairing. TMT steel bars become extremely bendable due to their exceptional Yield Tensile properties. These rods are ribbed for added strength. It evenly distributes the weight across the TMT bar. The ribs improve the grip on the concrete. During the construction process, it reduces the risk of sliding. The use of the TMT Bar helps a structure last longer. Maintenance requirements are slightly reduced due to the high weldability and adhesion, resulting in cost reduction.

Fe 415 Grade

Ideal for small-scale construction, Fe 415 TMT bars offer excellent ductility and easy bendability. Suitable for homes, low-rise buildings, and layouts, especially in earthquake-prone zones. Fe415D and Fe415S provide additional seismic stability.

Fe 500 Grade

A market-standard for residential, commercial, and multi-story projects. Fe 500D and Fe 500S variants offer improved ductility and seismic resistance. Best for mid- to large-scale construction with high tensile strength needs.

Fe 550 Grade

Designed for large infrastructure, bridges, and industrial projects. Offers excellent tensile strength and corrosion resistance, especially in coastal or underground environments.

Fe 600 Grade

The strongest TMT grade, perfect for mega-structures, highways, metros, and high-rise buildings. Reduced congestion in reinforcement and excellent corrosion resistance.

Ribbed Bars – Built for Stronger Grip

TMT Bars by Primegold are ribbed to offer better adhesion with concrete, reducing the risk of slippage. With high yield strength and ductility, these bars provide structural integrity and reduce long-term maintenance costs. Built with Thermex Cooling Technology, our bars have a ferrite-pearlite core and martensitic surface, making them flexible yet solid.

FAQs STRUCTURAL STEEL

To check the quality of TMT bars, ensure they are BIS-certified (ISI mark) and manufactured as per IS standards. Check for consistent diameter and weight, a clear and uniform rib pattern, and the ability to withstand bend and rebend tests without cracks. Primegold TMT bars are made with advanced technology to ensure high strength, ductility, and quality.

TMT bars are used in a wide range of construction projects, including residential buildings, commercial complexes, bridges, flyovers, dams, and industrial structures. Due to their strength and durability, Primegold TMT bars are especially suitable for structures in seismic and coastal zones.

TMT rods are not painted because paint can reduce the bond strength between the steel and concrete. Primegold TMT bars are designed with corrosion-resistant properties through their unique manufacturing process, making painting unnecessary. Additionally, the ribs on the surface must remain exposed to ensure proper bonding with concrete.

Primegold TMT bars offer several unique features such as high tensile strength, excellent ductility, corrosion resistance, and weldability. They are manufactured using advanced German Turbo TMT technology, ensuring consistent quality, uniform rib patterns, and long-lasting performance in all types of construction.
