What is the difference between TMT and CTD bars

Madhuri Priya24 Jun, 2024Business

TMT bars and CTD (Cold Twisted Deformed) bars differ mainly in their manufacturing process and mechanical properties. TMT bars undergo a thermo-mechanical treatment that enhances their strength, ductility, and corrosion resistance. In contrast, CTD bars are made by cold twisting hot-rolled steel, which can lead to surface cracks and reduced durability. TMT bars are generally preferred over CTD bars for modern construction due to their superior performance.
