TMT rebars

TMT Bars find use in core infrastructure development like construction of multi storey buildings, bridges, dams, railways, power plants as reinforcement material. We supply rebars which comes with a series of inherent advantages like consistent quality along with uniform grades, dimensions and tolerance, also with superior stability, properties for higher durability and easy workability.

Various grades of rebars
Fe 500, Fe 500D, Fe 550, Fe 550D, Fe 600

Sizes available
8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 32mm, 36mm, 40mm
