32mm TMT Bar Weight, Price, Uses, and Size Guide (2026)

“Whether you are planning a residential, commercial or infrastructure project, choosing the right TMT bar size and quality can help support a strong, durable and reliable structure.”

Planning a construction project? Choosing the right reinforcement steel is one of the first and most important steps when estimating material requirements. A clear understanding of 32mm TMT bar weight, size, grade and price can help you plan steel quantities and manage your material budget more effectively.

Among larger TMT bar sizes, 32mm TMT bars are generally used where larger-diameter reinforcement is specified by the structural design. The right selection depends on the type of structure, reinforcement requirements, project specifications and guidance from qualified professionals.

This guide covers 32mm TMT bar weight per meter, weight per piece, bars per ton, size and dimensions, price, common uses, grades and important factors to consider before buying.

What Is a 32mm TMT Bar?

A  32mm TMT bar is a steel reinforcement bar with a nominal diameter of 32 millimeters. TMT stands for Thermo-Mechanically Treated. After the bar is rolled, it is cooled quickly with water. This makes the outer layer hard and strong, while the inner core stays softer and more ductile.

The ribs on the surface help the bar grip the concrete, so the steel and concrete work together as one.

The 32mm size is chosen where the load is very high. One 32mm bar has about four times the cross-sectional area of a 16mm bar. This means a designer can use fewer, thicker bars instead of many thin ones, which leaves more room for concrete to flow around the steel in crowded sections.

32mm TMT Bar Weight Per Meter

The weight of a 32mm TMT bar is about 6.321 kg per meter.

A standard 12-meter bar weighs about 75.85 kg. That is roughly 64% heavier than a 25mm bar of the same length (46.30 kg).

These are theoretical weights. IS 1786 allows a small tolerance on mass, so actual bars can be slightly heavier or lighter. Always check the supplier’s weighment and invoice.

32mm TMT Bar Weight Chart

Cut lengths like 3 m or 4 m are common for starter bars and dowels, so this chart helps when you do not need a full 12 m bar.

32mm TMT Bar Weight Per Piece

Large orders are often counted in bars but billed by weight. This table helps you convert between the two.

For any cut length, multiply the length in meters by 6.321.

How to Calculate 32mm TMT Bar Weight?

The simple formula for TMT bar weight is:

Weight per meter (kg) = D² ÷ 162

Here, D is the bar diameter in mm. For a 32mm bar:

1. Square the diameter: 32 × 32 = 1,024
2. Divide by 162: 1,024 ÷ 162 = 6.321 kg per meter
3. Multiply by length: 6.321 × 12 = 75.85 kg

Example 1: A heavy column
A column uses 6 bars of 32mm, each 4 m long.

• Total length = 6 × 4 = 24 m
• Weight = 24 × 6.321 = about 151.7 kg

Example 2: A pile reinforcement cage
A pile cage uses 10 bars of 32mm, each 6 m long.

• Total length = 10 × 6 = 60 m
• Weight = 60 × 6.321 = about 379 kg

These examples do not include laps, hooks or wastage. Your bar bending schedule gives the final quantity.

How Many 32mm TMT Bars Are There in One Ton?

One ton is 1,000 kg. Divide it by the weight of one bar.

In running length, one ton of 32mm bar gives about 158 meters of steel.

A 10-ton truck can carry roughly 132 bars of 12 m, going by weight alone. Real loads also depend on the vehicle length and local transport rules.

32mm TMT Bar Size and Dimensions

The cross-sectional area decides how much tension a bar can carry. One 32mm bar has about 1.64 times the area of a 25mm bar and about 4 times the area of a 16mm bar.

Thick bars also need extra planning. They need larger bend diameters, more clear spacing and longer laps. On many large projects, designers use mechanical couplers to join bars instead of long laps. These details come from the structural design.

32mm TMT Bar Price in India (2026)

TMT bar prices are usually quoted per kg or per ton. They change often with raw material costs, brand, city and market demand. Because of this, a fixed price in a blog can quickly become outdated. Always ask your supplier for a written quotation on the day you order.

As an indicative guide, 2026 market rates have mostly been around ₹60–₹72 per kg (roughly ₹60,000–₹72,000 per ton). Premium brands typically price higher than secondary mills.

You can work out the cost with a simple formula:

Cost = Weight × Rate per kg

The table below uses indicative rates. These are not current market prices.

Every ₹1 change in the per-kg rate changes the cost of one 12 m bar by about ₹76 and the cost of a ton by ₹1,000. On a project using 30 tons, a ₹2 per kg difference between two quotes is ₹60,000. When comparing quotes, make sure the grade, delivery terms, GST and weighment method are the same.

Factors Affecting 32mm TMT Bar Price

• Raw material cost: Iron ore, scrap, sponge iron and billet prices
• Grade: Fe 550D can be priced differently from Fe 500 or Fe 500D
• Brand and quality control: Consistent weight, testing and certification
• Order quantity: Large project orders often get better rates than small lots
• Transport: Heavy 12 m bars cost more to move and unload
• Cutting and bending charges: Added if the supplier processes the bars
• GST: 18% GST is charged on top of the base price. See our [TMT Bar HSN Code guide].
• Market demand: Rates often rise in the post-monsoon construction season (October to March) and move with supply conditions

Uses of 32mm TMT Bars in Construction

• Bridge piers and abutments: Main vertical and tension steel
• Pile foundations and pile caps: Reinforcement cages and cap steel
• Heavy columns: Main bars in tall buildings and heavily loaded frames
• Large raft foundations: Thick mats under heavy structures
• Transfer beams and deep beams: Primary tension reinforcement
• Dams, tunnels and retaining structures: Heavy reinforced concrete sections

The bar size, number of bars and spacing must always follow the structural drawing.

32mm TMT Bar Grades: Fe 500, Fe 500D, Fe 550 and Fe 550D

TMT bar grades are defined in IS 1786, the Indian Standard for high-strength deformed steel bars. The number after “Fe” is the minimum yield or proof stress in N/mm². The letter “D” means the bar has higher ductility, which is a higher elongation requirement.

Grade does not change the size or theoretical weight of the bar. It changes strength and ductility. In heavy structures, a higher-strength grade can help reduce the amount of steel needed, and ductile grades help structures handle stress such as earthquake movement. Use only the grade your structural engineer has specified.

32mm TMT Bar vs 25mm and 40mm TMT Bars

From 25mm to 32mm, the weight per meter rises about 64%. From 32mm to 40mm, it rises about 56%. A bigger bar means more strength, but also higher cost and harder handling. Never swap one size for another without your engineer’s approval, because bar count, spacing and lap length all change. 

See our [TMT Bar Weight Guide] for other sizes.

How to Choose the Right 32mm TMT Bar for Your Project?

1. Follow the structural drawing. Size, number of bars, grade and lap details come from the design.
2. Match the grade exactly. Do not switch to a lower grade to save money.
3. Check for IS 1786 and BIS marking. The brand and grade should be rolled onto the bar.
4. Inspect the bars. Look for uniform ribs, straight bars, and no cracks or flaking rust.
5. Ask for test certificates. Batch reports should show yield strength, tensile strength and elongation.
6. Weigh a sample bar. A 12 m bar should be close to 75.85 kg, within the permitted tolerance.
7. Plan site handling. Heavy bars need lifting support, safe unloading and storage off the ground.
8. Confirm cutting and bending. Check who will process the bars and what it will cost.
9. Add allowance to your estimate. Include laps and wastage as per the bar bending schedule.
10. Verify the invoice. Description, grade, size, quantity, HSN code, GST and GSTIN should all be correct.

Before purchasing 32mm TMT bars, make sure the delivered material matches the structural drawing, specified grade, quantity and test documentation. For dependable reinforcement steel, check SSI TMT’s Fe 550D TMT Bar and compare its specifications with your project requirements.
