The importance of reliable reinforcement steel has never been greater across the construction sector. The strength and safety of a structure depend heavily on the quality of the TMT bars used, making it essential to understand their specifications before choosing them. Grade, chemical composition and mechanical properties, with the manufacturing process – all influence how TMT bars perform over time.
Adukia Industries, known for producing high-quality steel, offers TMT bars engineered with precision and backed by transparent specifications that ensure durability, ductility, weldability, and corrosion resistance.
This article breaks down the specifications of Adukia’s TMT bars in clear detail so that you will learn about the details of these TMT bars.

Concrete gains its true strength when paired with high-performance reinforcement steel. Understanding the mechanical behaviour of Adukia’s TMT bars helps builders and engineers assess how they will respond to stress, strain, and long-term usage.
Adukia’s UltraMax Fe 550D TMT specification offers a minimum yield strength of 570 N/mm² and an ultimate tensile strength of up to 630 N/mm². This makes them significantly stronger than many conventional options in the market. Their high strength supports the reduced consumption of steel without compromising on safety. These bars perform reliably in structures that experience substantial loads, such as industrial buildings, high-rise towers, and bridges.
Adukia’s Fe 550D bars provide up to 20% elongation, enabling the steel to bend and deform safely without fracturing. This characteristic is especially valuable in regions with seismic activity. Where structures must absorb shock and redistribute stress without sudden failure these TMT bars are suitable. The ductility of these bars also enhances handling and bending efficiency on-site. It can lower the risk of breakage and reduce wastage during reinforcement work.
The thermal resistance of Adukia’s TMT bars ensures that structural stability is retained even during exposure to elevated temperatures. They can withstand up to 500°C without significant loss in strength, and even at 550–600°C, they retain performance within safe margins.
The Thermex processing creates a refined surface layer that improves resistance to corrosion. This feature is particularly important in coastal regions and humid zones, or areas prone to moisture. In these regions long-term exposure can weaken conventional reinforcement steel.
Using advanced German Thermax technology, Adukia manufactures Fe 550 grade TMT bars in sizes from 8mm to 32mm, delivering high strength, durability, and reliable performance for all types of construction.

The specifications of any TMT bar only hold value if they are consistently met during production. Adukia ensures uniformity and reliability through an advanced manufacturing system supported by rigorous quality checks.
Adukia’s TMT bars are manufactured using the Thermex quenching process. It produces a bar with a strong outer layer and a ductile core. This combination enhances both performance and safety, ensuring that the bars provide the ideal balance between rigidity and flexibility. The bars are rolled from in-house manufactured billets. This gives Adukia full control over the purity and consistency of raw materials, which directly impacts structural reliability.
Adukia conducts extensive testing at every production stage.
Adukia TMT Bars are designed to deliver strength, safety, and long-term performance for modern construction needs. Manufactured with advanced technology, they ensure reliable quality and durability for every structure.
Every construction project demands reinforcement that suits its scale and load profile with environmental conditions. Matching these needs with the correct specifications ensures proper performance and cost efficiency.
Lower grades such as Fe 500 may be sufficient for beams, slabs, and footing applications. These grades provide adequate strength while maintaining excellent workability and weldability.
Fe 550D offers a suitable balance of higher strength and enhanced ductility, making it ideal for buildings that require both structural rigidity and flexibility.
UltraMax Fe 550D bars are well-suited for heavy load conditions. It is because of their high yield strength and superior tensile capacity with resistance to corrosion and heat.
The combination of high ductility and low carbon equivalent with corrosion resistance makes Adukia’s Fe 550D bars a dependable option. It is suitable especially for areas exposed to tremors, saline air, or frequent moisture.
Selecting the right TMT bar is not merely a procurement decision but shapes the long-term safety, performance, and durability of a structure. Adukia Industries TMT bars features offer clear and well-defined specifications that assist engineers and builders in making confident choices. Their specifications support diverse project requirements-from homes and commercial buildings to industrial and infrastructure developments.
