TMT Bars

Product Description

Manufacturing Process: TMT bars are produced using a modern and efficient manufacturing process known as Thermo-Mechanical Treatment. In this process, the steel billets are heated to a high temperature (around 1,100 degree C - 1,200 degreeï C) and then rapidly cooled using water jets or air quenching. This rapid cooling, followed by controlled cooling in the air, results in the formation of a tough outer layer with a soft inner core, imparting superior strength and ductility to the bars.

Ribbed Design: TMT bars typically feature a ribbed surface design, which enhances their bond with concrete. The ribs provide better grip and prevent slippage between the steel and concrete, ensuring effective load transfer and enhancing the structural integrity of the reinforced concrete members.

ïCorrosion Resistance: TMT bars are manufactured with special alloying elements such as chromium and copper, which impart excellent corrosion resistance to the bars. This ensures the durability and longevity of the reinforced concrete structures, particularly in corrosive environments or coastal regions.

ïDuctility and Bendability: TMT bars exhibit high ductility, allowing them to undergo significant deformation without fracturing. This property makes them highly bendable, facilitating ease of handling and fabrication on-site. TMT bars can be bent to various shapes and angles without compromising their structural integrity.

ïWeldability: TMT bars are also highly weldable, allowing for easy and efficient welding with other steel components during construction. Proper welding techniques must be employed to maintain the mechanical properties and integrity of the welded joints.

ïOverall, TMT bars are preferred over traditional mild steel bars due to their superior strength, ductility, corrosion resistance, and bond characteristics with concrete, making them a reliable choice for modern construction projects.

SPECIFICATION----Applications: TMT bars are widely used as reinforcement in reinforced concrete structures such as buildings, bridges, dams, roads, and other infrastructure projects. They provide the necessary tensile strength to withstand bending and shear forces, enhancing the structural stability and load-bearing capacity of the concrete elements.

Grades: TMT bars are available in various grades, which denote their tensile strength. Common grades includeï Fe500, Fe550, and Fe550d, where the numbers represent the minimum yield strength of the bars in megapascals (MPa). Higher-grade TMT bars offer greater strength and are suitable for use in high-rise buildings and heavy-duty structures.

Diameter: The diameter of TMT bars is one of the primary size specifications. It is commonly measured in millimeters (mm). The most commonly used diameters for TMT bars range from 8 mm to 32ï mm, The diameter of the TMT bar determines its load-bearing capacity and suitability for different structural applications.

Length: TMT bars are usually available in standard lengths ranging from 6 meters to 12 meters.ï Straight andï bend .However, custom lengths may also be available based on project requirements. Longer lengths help in reducing the number of joints and improving the overall structural integrity of the reinforced concrete members.

Weight per Meter: The weight of TMT bars per meter length is another important specification. It is calculated based on the density of steel and the cross-sectional area of the bar. The weight per meter varies depending on the diameter and grade of the TMT bar. Standard weight per meter values are often provided by manufacturers for different diameters and grades.

ïShape: TMT bars are typically available in round or circular shapes. The round shape is the most common and widely used for reinforcement in concrete structures. However, some manufacturers may offer TMT bars in other shapes such as square or rectangular for specific applications.
