SRMB TMT Bars
ABOUT SRMB TMT BARS
SRMB TMT is India’s most advanced earthquake resistant steel. The Upgradation from SRMB 500+ SR X ribs to SRMB 500+ SR WINGRIP (seismic resistant) is a result of the adoption of new technology and extensive in house research and development which provides more strength with higher elongation and better bonding with concrete. SRMB TMT bar of SR quality is manufactured to demonstrate higher ductility through a special chemistry of the billets and critically controlled post rolling TMT treatment to enlarge the gap between the Yield Strength and the Ultimate Tensile Strength. A highly critical balance between the chemistry and the quenching parameters.

PRODUCT BENEFITS
Supirior Strength
The SRMB TMT Bars
(in all their different grades) are
stronger than the conventional bars.
Improved Elongation
Greater strength with higher
elongation is one of the unique
features of the SRMB TMT Bars.
Increased Ductility
The increased elasticity gives the
bars a fantastic bending ability
during construction.
Corrosion Resistant
SRMB TMT Bars helps prevent
corrosion and enhance the life
of the structures.
High Load Resistant
The high fatigue-resistant property of the SRMB
TMT BARS helps in the dynamic loading
on account of the high strength of
the surface layer.
Superior Weld-ability
SRMB TMT Bars, because they have low
carbon equivalent content, can be used for
butt/lap and other weld joint without
reduction of strength at the weld joints.
