TMT Bar Weights

TMT Bar Weights: A Comprehensive Guide for 8mm, 10mm, 12mm, and 16mm Rods

TMT bars, also known as Thermo-Mechanically Treated bars, are integral components in construction projects, offering strength, durability, and flexibility. Understanding the weight specifications of TMT bars is crucial for architects, engineers, and builders to ensure structural integrity and safety. In this blog post, we delve into the weight charts for TMT bars of varying diameters, specifically focusing on 8mm, 10mm, 12mm, and 16mm rods.

8mm TMT Bar

The 8mm TMT bar is commonly used in light construction projects and residential buildings. It offers sufficient strength while being lightweight, making it ideal for smaller structures and load-bearing walls. The weight of an 8mm TMT bar per meter can vary slightly based on the manufacturer and quality standards, typically ranging from X kg/m to Y kg/m.

10mm TMT Bar

With slightly more strength compared to the 8mm variant, the 10mm TMT bar finds applications in medium-sized constructions, including commercial buildings and bridges. The weight of a 10mm TMT bar per meter typically falls within the range of X kg/m to Y kg/m, offering a balance between durability and flexibility.

12mm TMT Bar

The 12mm TMT bar is widely used in reinforced concrete structures, such as beams, columns, and slabs, where higher strength and load-bearing capacity are required. The weight of a 12mm TMT bar per meter usually ranges from X kg/m to Y kg/m, making it suitable for a diverse range of construction projects.

16mm TMT Bar

Among the thicker TMT bars, the 16mm variant offers substantial strength and resilience, making it indispensable in heavy-duty constructions like bridges, high-rise buildings, and industrial structures. The weight of a 16mm TMT bar per meter typically varies from X kg/m to Y kg/m, providing robust support in demanding environments.


  • The weight values are approximate and may vary slightly depending on the manufacturer and specific TMT bar grade.
  • The standard length of TMT bars is 12 meters.
  • The number of rods per bundle and the bundle weight can also vary depending on the manufacturer.


In conclusion, understanding the weight specifications of TMT bars is essential for architects, engineers, and builders to ensure structural stability and safety in construction projects. By referencing weight charts for 8mm, 10mm, 12mm, and 16mm TMT bars, stakeholders can make informed decisions regarding material selection and design considerations, ultimately contributing to the success and longevity of the built environment.
