Aditya TMT Bars offers a blend of strength and ductility, far in excess of the minimum limits of yield stress in the IS : 1786 standards. The typical values are as high as 450 N/mm2 though the standards specify 415 N /mm2 as normally used by architects. The typical value of ductility as measured by elongation is 18% minimum as against the standard value of 14.5% minimum. Undoubtedly, this ductility guarantees higher levels of safety.

Mechanical Testing
A team of qualified and skilled personnel in combination with state-of-the-art quality testing equipment undertakes complete testing like:

• Impact Testing
• Tensile Testing
• Hardness Testing
• Microstructure Testing
• Elasticity
• Yield Stress

Impact Testing
Premium quality impact testing machines are capable to conduct impact test as per ISI specification

Tensile Testing
Universal Testing Machine is used to test the metals with strength up to 1000 kN. TMT bars can be tested up to 32 mm capacity as per IS 1786 without machining.

Hardness Testing
There a host of Hardness testing equipment duly calibrated by internationally known auditors.
