Tmt bars (size from 8mm to 25 mm). Certfi ation:is : 1786. Ideally suitable for all kinds of reinforced concrete work especially where high strength and high bond value is required.
We are supplier and exporter of TMT Rebars. 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.

* In the field of constructions, steel acts as a powerful structure, which creates a high strength, durability and stability. Steel is an alloy of iron and carbon and sometimes other elements. It is a low cost and a significant component used in buildings, infrastructures, tools, machines, appliances, etc. * Steel being the most preferred choice for construction has great benefits. The buildings are made up of different types of steel, which forms a structural framing system, saves time and less expensive * Steel reinforcement bars or rebars are used to improve the tensile strength of the concrete. * Steel is only used as rebar because elongation of steel due to high temperatures (thermal expansion coefficient) nearly equals to that of concrete Types of Steel Reinforcement Bars * Major types of steel bars used in the construction I.Mild Steel Bar * The surface of the mild steel bars are plain and round in shape. They are available in various sizes of 6 mm to 50 mm. They are used in concrete for special purposes, such as dowels at expansion joints, where bars must slide in a metal or paper sleeve, for contraction joints in roads and runways, and for column spirals. They are easy to cut and bend without damage. Grades in mild steel bars 1. Mild Steel Bars Mild steel bars grade-I designated as Fe 410-S or Grade 60. Mild steel bars grade-II designated as Fe-410-o or Grade 40. 2. Medium Tensile Steel Bars designated as Fe- 540-w-ht or Grade 75. II.Deformed Steel Bar Deformed steel bars have ribs, lugs and indentation on the surface of the bar, which reduces the major problem that is faced by mild steel bar due to slippage and good bonding is achieved between concrete and rebar. The tensile properties is higher compared to other rebars. These bars are produced in sections from 6 mm to 50 mm dia. 1. TMT Bars (Thermo Mechanically Treated Bars) Thermo Mechanically Treated Bars are hot treated bars that are high in strength used in reinforced cement concrete (RCC) work. It is the latest induction in the MS steel bars with superior properties such as strength, ductility, welding ability, bending ability and highest quality standards at international level. Characteristics of TMT Rebars Better ductility and malleability High yield strength and toughness More bonding strength Earthquake resistance Corrosion resistance High thermal resistance Economical and safe in use No loss in strength at welded joints Ordinary electrodes used for welding the joints 2. High Strength Deformed Bars High strength deformed bars are cold twisted steel bars with lugs, ribs, projection or deformation on the surface. It the extensively and majorly used for reinforcement purposes in a construction. These bars are produced in sizes or sections from 4 mm to 50 mm in diameter.
We offer TMT Bars of following cross sections. Length: 6- 12 meter as per customer requirement. We also supply cut and bend TMT as per the Ring sizes required by the construction projects. Grades: FE 500, FE 500D, FE 600 Standards: IS -1786, ASTM A 615 Grade 60, JIS G 3112-2004 etc.

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.
