GTB® Steel Process & Quality
Designed for perfect
bonding, lengthened
durability and
heightened safety
Our Cutting-Edge Process
Microprocessor-based, Programmable Logical Controlled (PLC) re-heating furnace is used for heating billets sourced from prime steel mills and then rolled through a series of mill stands, progressively reducing the section to end size and shape range to produce bars at controlled temperatures. Subjecting to THERMEX Thermomechanical Process immediately after the bars leave their final stand while achieving the desired result of finished GTB® TMT RB500 steel bars of profound quality.

Higher Tensile Strength
GTB® TMT RB500 steel bars with a yield point of not less than 500 enables structural engineers designing RCC structures using 8% less steel without compromising on the strength.
More Corrosion Resistance
Precise control of the ThermoMechanical Treatment process results in a uniform and thick Martensite layer free of residual stresses and the dense oxide layer around the bar remains intact in the process. The martensite layer and preserved oxide layer improve the corrosion resistance property of GTB® TMT RB500 bars.
Surpassing Quality Standards
Highest quality standards maintained at GTB® Steel conforms to international standards. Rigorous tests, strictest controls and monitoring of input and production throughout the production process of GTB® TMT RB500 steel bars surpass the standards.
