TMT Bars

description

Features

Fire & Corrosion Resistant

SEL TMT Bars are fire resistant from 600°C to 650°C. The combined chemistry of steel and advanced quenching process makes SEL TMT fire and corrosion resistant.

Earthquake Resistant

Balanced proportion of Carbon and Manganese exhibit a good carbon equivalent (CE) that may not be greater than 0.42%, resulting in higher elongation and better bendability to resist Earthquake

Savings

Use of Fe500D over Fe418 ensures savings in usage of steel by up to 17%. SEL TMT Bar comes with lower and uniform sectional weight resulting in further saving of 3-4%

Quality bonding with RCC

Shyam SEL TMT Bars have uniform rib pattern, which is designed by automated CNC machine. Uniform rib pattern on the TMT Bar helps in quality bonding with reinforced concrete cement.
