When quality and performance are non-negotiable, GK TMT 550 D bars stand out as the best 550 D TMT bars in India.
Backed by over 24 years of industry excellence, GK TMT has been at the forefront of manufacturing high-grade, reliable, and NABL-certified steel bars for projects that shape India’s skyline and infrastructure.
What is a 550 D TMT Bar?
The “550 D” in TMT bars indicates a minimum yield strength of 550 MPa with enhanced ductility. The “D” stands for ductile grade, which means better flexibility while maintaining high tensile strength—perfect for high-rise buildings, bridges, dams, and industrial complexes.
550 D vs. Other Grades – Why It Matters for Your Project
While standard TMT bars may suffice for general structures, 550 D bars offer an optimal balance between strength and elongation. This makes them more reliable under pressure and more cost-efficient in terms of material consumption and structural integrity.
Why GK TMT 550 D Bars Are the Best in the Market
At GK TMT, we manufacture 550 D grade TMT bars using advanced Thermex technology and maintain zero tolerance for quality compromise. Here's why our product is trusted across industries:
GK TMT 550 D bars offer exceptional strength-to-weight ratio, reducing the quantity of steel required without compromising safety.
Ideal for seismic-prone regions, GK TMT 550 D bars have enhanced elongation properties, which allow structures to absorb shock and stress during earthquakes.
Our bars feature specially designed ribs and surface texture, ensuring a stronger grip with concrete, minimizing slippage and increasing the life of the structure.
GK TMT 550 D bars are built to resist rust and high heat, making them suitable for coastal, industrial, and high-temperature environments.
Every batch of GK TMT 550 D undergoes rigorous quality control in our NABL-accredited labs, ensuring unmatched consistency in mechanical and chemical properties.
