Tmt Bars

TMT Bars

TMT Bars / Rebar which find usage in the core infrastructure development like construction of Multi Storeyed buildings, bridges, dams, railways, power plants as reinforcement material. These bars are rolled from Tested billets as per IS 2830 which ensures uniform physical and mechanical properties. The range varies from 8mm to 32mm, conforming to BIS 1786 - Fe 415 and Fe 500.

SV Trade is a leading supplier & Exporter of TMT Bars, according to appropriate standards as well as customer specifications in a large variety of steel grade and dimensions. Specific requirements on execution, tolerances, lengths, mechanical and corrosion properties are offered on request

Rebar couplers are used in reinforced concrete structures to replace normal rebar lap joints. Each rebar coupler consists of a piece of rebar equipped with a thread and coupler sleeve at the right end as viewed in the direction of installation. ...

HISTORY

For year’s, Bamboo has been used by man for construction activities, later it has been replaced by CTD (Cold Twisted Deformed steel rods) or TOR steel rods. The manufacturers adopted the Cold Twisting Process in which the naturally cooled rods were twisted by means of motors. Thus the molecular structure of the core steel is weakened. Thus it should not be used for construction activities.

Now, the TMT (Thermo Mechanically Treated) steel bars have emerged.

Description

TMT Bars, Thermo mechanically treated bars are high strength deformed steel bars used in reinforced cement concrete (RCC) work manufactured with the help of advancement of technology. TMT bars are latest production in MS steel bars and have superior properties such as strength, ductility, welding ability, bending ability and highest quality standards at international level.

TMT Bars (Thermo Mechanically Treated) Steel, can be described as new-generation-high-strength steel having superior properties such as Weldability, Strength, Ductility, and Tensility, Which meet the highest international quality standards.
One of the most common types of TMT Construction is used for home and building construction. The production of quality TMT Bar depends on three major factors - quality raw materials, a properly designed and automated mill, and a well-designed quenching and temping technology. All bars must be purchased based on the properties of yield strength, tensile strength, and elongation values.

The range we provide starts from a 6mm round bar in the required length.
