Maintains Quality CUTS COSTS
Tiscon 500, the high strength ribbed
reinforcement bar from Tata Steel has been specially created for high strength
applications. It is ideal for applications like dams, bridges, highrises or any other
critical structure where high yield strength is required without compromising on the
Distinctly superior to standard Fe 415 bars, TISCON 500,
which corresponds to BIS Fe 500, also ensures a reduction of upto 17% in steel usage,
while delivering the same strength.
Higher BOND STRENGTH
The rib pattern of TISCON 500 has been
specially designed to ensure that excellent bond strength is developed between the bar and
the surrounding concrete. The design and profile of the rib and its replication throughout
the length of the bar by using automated milling machines results in uniform and precise
ribs leading to uniform strength.
While the specification stipulates that
bond strength should be 40% higher than that of Mild Steel plain bars, TISCON 500 has
typical values, which are higher by as much as 100%. This leads to increased safety and
durability of the structure even in the most hazardous environments.
Normal Fe 500 grade as specified by BIS
1786 standards are associated with lower ductility. But TISCON 500 are higher strength
rebars with elongation implying that you can economize on steel consumption without
No wonder, use of TISCON 500 leads to
savings of upto 17% in cost over Fe 415 grade rebars.
Due to the controlled process of
manufacturing rebars under theTempcore Process the tough outer surface and soft core of
TISCON 500 results in a rebar with excellent values of bendability. The bar can be bent
around mandrels much smaller than those specified in IS 1786. This has obvious advantages
at construction sites.
Contrary to the normal practice of
increasing strength by increasing the carbon content of the bar, TISCON 500 is produced
with low carbon and carbon equivalent. The higher strength property is imparted through
precisely controlling the parameters of thermo mechanical treatment to ensure
superior weldability, when compared to conventional cold twisted bars. It can be
butt-welded or lap-welded using simple welding practices using ordinary rutile coated
electrodes of matching strength. Generally, no pre and post welding treatment is required.
Higher CORROSION RESISTANCE
The precise control of the thermo
mechanical treatment process, results in a uniform and thick tempered martensitic rim,
completely free from internal stresses. This martensitic rim improves the corrosion
resistance of TISCON 500 as well as the fatigue strength, when compared to traditional
cold twisted bars.
TISCON 500 is supplied with mass/metre on
the negative side of the specified tolerance on a weighted average basis. This further
reduces consumption because of extra length per unit mass.
Superior SEISMIC RESISTANCE
Due to its unique combination of strength
and ductility, TISCON 500 can adequately support a seismic design. When evaluated for
resistance to seismic loads on column joints in a RCC structure, the energy dissipation
was found to be almost same for each cycle indicating very high and uniform ductility
maintained under such loads.
