Calculate the exact weight of T Bars and Tee Sections in Mild Steel (MS), Stainless Steel (SS), and other metals instantly with our free online calculator. Simply enter your flange width, flange thickness, web height, web thickness, and length in mm or inches, and get accurate results in both kg and lbs.
Weight Calculation for T Bar and Tee Section
The weight of a T Bar (also known as a Tee Section or T-Profile) is determined by its cross-sectional area, which consists of a horizontal flange and a vertical web. These profiles are widely used in structural framing, shipbuilding, bridge construction, and mechanical supports due to their ability to resist bending and shear forces. The standard density for Mild Steel is 7.85 g/cm³. Accurate weight calculation is essential for structural load planning, material procurement, and precise cost estimation in fabrication projects. For more complex structural shapes, you can also use our comprehensive Metal Weight Calculator.
T Bar Weight Formula and Manual Calculation
The industry-standard formula for calculating T Bar weight involves summing the area of the flange and the web, ensuring the intersection is not double-counted:
Weight (kg) = [ (Flange Width × Flange Thickness) + ((Web Height - Flange Thickness) × Web Thickness) ] × Length (m) × Density Factor
Density Factors for common materials:
0.00000785 for Mild Steel (MS) & Carbon Steel
0.00000793 for Stainless Steel (SS 304/316)
0.00000270 for Aluminium
0.00000896 for Copper
For imperial units (inches and lbs):
Weight (lbs) = Cross-Sectional Area (in²) × Length (ft) × 3.4 (for Steel)
Step-by-Step Calculation Example
- Step 1: Identify dimensions: Flange Width = 100 mm, Flange Thickness = 10 mm, Web Height = 100 mm, Web Thickness = 10 mm, Length = 1 m (Mild Steel)
- Step 2: Calculate Flange Area: 100 × 10 = 1000 mm²
- Step 3: Calculate Web Area (excluding flange overlap): (100 - 10) × 10 = 90 × 10 = 900 mm²
- Step 4: Total Cross-Sectional Area: 1000 + 900 = 1900 mm²
- Step 5: Apply formula: 1900 × 1 × 0.00000785 = 14.92 kg/m
- Step 6: Convert to lbs (optional): 14.92 × 2.20462 ≈ 32.89 lbs/m
This calculation aligns exactly with the results provided by the T bar weight calculator.

Frequently Asked Questions
What is the formula for T Bar weight?
The formula for T Bar weight is: Weight = [ (Flange Width × Flange Thickness) + ((Web Height - Flange Thickness) × Web Thickness) ] × Length × Density Factor. This ensures the corner where the flange and web meet is only counted once. For quick calculations, use our Metal Weight Calculator.
How much does a 50x50x6mm MS T Bar weigh per meter?
A standard 50x50x6mm Mild Steel T Bar weighs approximately 4.57 kg per metre. This is calculated by adding the area of the flange (50x6) and the remaining web (44x6), then multiplying by the density factor of 0.00000785.
What is the difference between a T Bar and an Angle Bar?
A T Bar has a 'T' shape with one central web and a top flange, providing strength in one primary direction. An Angle Bar (L-Bar) has two legs meeting at a 90-degree angle. T Bars are often used for stiffeners and supports, while Angle Bars are used for framing and brackets. The weight calculation for each differs due to their unique geometries.
Conclusion
Accurately determining the weight of T Bars and Tee Sections is essential for precise structural analysis, material procurement, and cost estimation in engineering projects. Whether you are working with standard Mild Steel, corrosion-resistant Stainless Steel, or lightweight Aluminium, using the correct geometric formula ensures your project estimates are reliable. By utilizing our comprehensive Metal Weight Calculator, you can instantly calculate the exact weight in kg or lbs for any T-profile dimension, streamlining your fabrication workflows and ensuring efficient resource management.
