Answer / Amar Deep Singh

Both TMT (Thermomechanically Treated) steel and HYSD (High Yield Strength Deformed) steel have their advantages, and the choice between them depends on the specific project requirements.
1. TMT Steel: It is corrosion-resistant due to its thermal treatment process. It also has better ductility, making it more suitable for seismic zones. However, it may be slightly more expensive than other types of steel.
2. HYSD Steel: It offers high yield strength and improved formability, making it ideal for complex structural designs. However, its corrosion resistance is generally lower than TMT steel, especially in coastal areas or other environments with high humidity levels.
