A Superior Product by Industry Standards

Kalinga TMT Fe 550 bars are built to last. They are exceptionally strong, corrosion resistant, and have excellent bending property; giving them the strength to withstand enormous loads, earthquakes, and shakes.

Key Features

Excellent Weld-ability

Kalinga TMT Fe 550 bars have a low carbon equivalent which gives them excellent weld-ability. This superior weld-ability ensures that the bars can be butt-welded or lap-welded using ordinary rutile-coated electrodes of matching strength. No pre-treatment or post-treatment is required thus saving time and construction cost.

High Seismic Resistance

Kalinga TMT Fe 550 bars undergo rigorous testing at our research facilities. Repeated reverse loading pressure is applied to test the strength and flexibility. With energy dissipation remaining near to constant during each test cycle, our bars have a proven superiority compared to the competition. UTS/YS ratio (Ultimate Tensile Strength and Yield Strength ratio) is maintained along with Percentage Elongation testing to ensure that Kalinga TMT Fe 550 bars can handle the load in earthquake prone areas.
