Give your home the Triam A+ Fe 550D promise of A+ Strength, A+ Flexibility and A+ Grip, and make it last beyond a lifetime.
Triam A+ Fe 550D new-age construction rebars achieve a unique combination of strength and ductility through the superlative
manufacturing process. Due to proper quenching, self-tampering, atmospheric cooling, and controlled carbon equivalent
percentages, Triam A+ Fe 550D has increased exibility and strength. The higher ductility of Triam A+ Fe 550D facilitates the
distribution of load in well-designed statically non-determinant structures. It facilitates the distribution of load and provides the
best solution for structures prone to earthquakes owing to its high dissipation of energy.
Triam A+ Fe 550D further conforms to all parameters of IS:1786:2008 as well as Para 5.3 of IS:13920:2016 for all seismic zones.
In the case of yield strength for Triam A+ Fe 550D, the standard specification stipulates a minimum of 550 N/mm². For the same
product, the minimum value of elongation according to IS:1786:2008 is 14.5 % but we provide a value of 17%. Undoubtedly the
superior indices of strength and ductility are a guarantee of higher levels of safety for ages. TS/YS ratio and total elongation
percentage are important properties in rebars that reect the ability to handle the pressure of earthquakes.
Triam A+ Fe 550D new-age rebars conform to Fe 550D, IS:1786:2008 specification. Their carbon levels are lower
than the specifications, which result in its excellent ductility, high bending capability, better corrosion resistance
and a superior welding strength.
Consistent superior strength and high ductility are key attributes of Triam A+ Fe 550D new age rebars. These factors
go much higher than the prescribed norms of IS:1786. Controlled chemical composition, by virtue of our own
in-house rolled billets ensure low Carbon and high Manganese content, helping the rebars retain their optimum
strength even at temperatures as high as 6000 Celsius. Additionally, controlled Sulphur and Phosphorus levels in the
rebar make it corrosion resistant. Triam A+ Fe 550D can widely be used in construction of office buildings, residential
complexes, warehouses, schools, dams, power plants and iconic super-structures.
Advantages at a Glance
When you buy Triam A+ Fe 550D new-age rebars you can be assured that you have ticked all the right boxes when it comes to A+ quality.
PRODUCT TRUTHS
BENEFITS
100% tested captive billets
Resulting in 100% controlled chemical composition of the billet in the sequence to produce TMT.
Anti-corrosion properties
Controlled chemical composition of S% & P% leads to better corrosion control.
Better flexibility
Higher elongation percentage compared to other products lend advanced safeguarding properties against earthquakes and other natural calamities.
Superior strength
Minimum strength of 600N/mm2 ensuring maximum support to structures, making it superior to other TMT bars.
Greater AR (Area of Rib) value
Resulting in a good bonding between steel and concrete.
Easy bending and re-bending
Resulting in enhanced productivity of the masons.
Fire resistance
Controlled chemical composition and advanced quenching processes help in instilling the TMT bars with resistance to extreme temperatures of 6000C – 6500C.
Earthquake resistance
The optimal combination of strength and exibility makes Triam A+ exhibit superlative earthquake resistance.
Dimensional Tolerance
Triam A+ Fe 550D is manufactured keeping it within the standard range of sectional weight with negative tolerance according to IS:1786:2008. This ensures higher meterage per unit weight for Triam A+ Fe 550D as compared to ordinary rebars.
Seismic Resistance
Several studies were conducted on concrete beam, column and joints reinforced with Triam A+ Fe 550D to evaluate its
performance under repeated reversed loading with large deformations as would be encountered during an earthquake. The
energy dissipation was found to be almost same for each cycle, indicating uniformly maintained ductility. The tests revealed
superior seismic resistance properties for Triam A+ Fe 550D.
Corrosion Resistance
Triam A+ Fe 550D is produced using Thermex Technology from HSE, Germany. Therefore, there are no torsional residual stresses in
the rebar, which results in superior corrosion-resistant characteristics compared to traditional cold twisted bars. On account of its
composite and uniform microstructure, Triam A+ Fe 550D has comparatively better corrosion-resistant properties compared to
other TMT bars, while being embedded in concrete.
