GBR TMT Fe 550 is the high yield strength rebar with specifications that ensure maximum savings on steel consumption.
- High Yield Strength of minimum 550 N/mm2
- Tensile Strength of minimum 585 N/mm2
- Steel savings of 10% compared to traditional Fe 500 grade rebars
- Ideal for high rises and large projects.

AVAILABLE IN MULTIPLE GRADES TO CATER TO ANY PROJECT SPECIFICATION:
Our integrated facility enables us control on the chemical composition of Billets to meet the norms of various rebar grades as defined by the Bureau of Indian Standards. Further, the PLC controlled thermo-mechanical treatment process helps maintain the desired yield strengths.
GBR TMT is available in Fe 550, Fe 500D & CRS Grades to ensure that we provide our customers the flexibility to design the structure as per the site conditions and requirements.
GBR TMT is available in the following sizes, as per the IS 1786:2008.
Other Products
More refined chemistry with Sulphur & Phosphorus content maintained under 0.040% and higher elongation values of over 16% making it the ideal for use in higher seismic zones.
