By Quick answer: For houses and buildings in Varanasi, Fe 500D TMT bars are the common choice because the "D" grade has better ductility, which matters in seismic zone III, where Varanasi lies. Buy by weight (per ton), check the brand embossing and the mill test certificate, and compare quotes on the delivered price. Get bulk TMT quotes.
What TMT means and why the grade matters
TMT stands for Thermo-Mechanically Treated. The process gives the bar a hard outer surface and a softer, ductile core, so the bar is strong but bends instead of snapping. TMT bars in India are made to the BIS standard IS 1786. The number in the grade is the minimum yield strength in N/mm².
| Grade | Typical use |
|---|---|
| Fe 500 | General RCC in small buildings |
| Fe 500D | Houses and multi-storey buildings; better elongation and ductility |
| Fe 550D | Heavier structures, bridges and industrial work where higher strength is designed |
The "D" grades have tighter limits on carbon, sulphur and phosphorus and higher elongation. Varanasi lies in seismic zone III, so most engineers specify Fe 500D for homes. Always follow your structural drawing.
Weight per metre: the number every buyer should know
Steel is sold by weight, so knowing the theoretical weight helps you check a delivery. The standard formula is D² ÷ 162 kg per metre, where D is the diameter in mm.
| Diameter | Weight per metre (approx.) | Weight of a 12 m bar |
|---|---|---|
| 8 mm | 0.395 kg | 4.74 kg |
| 10 mm | 0.617 kg | 7.40 kg |
| 12 mm | 0.888 kg | 10.66 kg |
| 16 mm | 1.580 kg | 18.96 kg |
| 20 mm | 2.469 kg | 29.63 kg |
| 25 mm | 3.858 kg | 46.30 kg |
If a bundle weighs far less than the count × weight, ask questions before you pay.

How to spot genuine bars
- Embossing: the brand name and grade are rolled onto the bar at regular intervals.
- Mill test certificate (MTC): ask for it with bulk orders; it shows chemical and mechanical properties for the heat.
- ISI mark and licence number on the tag.
- Uniform ribs along the bar and no rust flakes or cracks.
- A GST invoice that names the brand, grade, diameter and weight.
Comparing bulk quotes
Ask each supplier for the rate per ton by diameter (small diameters often cost a little more), cutting and bending charges if needed, freight, unloading and the delivery date. Many builders book 5 tons at a time for each slab, which keeps storage simple. Store bars off the ground on wooden sleepers, covered from rain.
Steel with cement, bricks and sand
Steel is one part of the structure budget. See our guides to bulk cement, bricks and blocks and sand and aggregates. Fabrication shops in Ramnagar also take cutting and bending work; see industrial supply and job-work orders.
How much steel does a house need?
Your structural engineer's bar bending schedule gives the exact quantity. For early budgeting, builders often use a thumb rule of roughly 3.5 to 4.5 kg of steel per square foot of built-up area for an ordinary RCC frame house, which works out to about 3.5 to 4.5 tons for a 1,000 sq ft floor. Heavier loads, larger spans and more floors increase this. Footings and columns use mainly 12 mm to 20 mm bars, beams 12 mm to 16 mm, slabs 8 mm to 12 mm, and stirrups 8 mm.
Common mistakes to avoid
- Mixing grades on one site. Keep Fe 500D for the whole structure if that is what is designed.
- Buying by piece without weighing. Always check the weighbridge slip or weigh a sample bundle.
- Leaving bars in the rain for weeks. Light surface rust is normal, but flaking rust reduces the effective diameter.
- Ignoring lap length and cover during fixing. Good bars are wasted if the bending and placement are poor; your engineer should inspect before every pour.
- Not planning cutting and bending. Pre-cut and bent bars from a fabricator reduce site wastage on larger projects.
Builders on larger sites should also ask suppliers about rolling-mill direct supply versus dealer stock, since direct orders usually need larger minimum quantities.
Key takeaways
- Fe 500D is the usual choice for homes in seismic zone III.
- Buy by weight and check against D² ÷ 162 kg/m.
- Ask for the MTC, ISI tag and a GST invoice with grade and diameter.

Frequently asked questions
Which TMT grade is best for a house in Varanasi?
Most engineers specify Fe 500D for homes because it combines strength with ductility, which is useful in seismic zone III.
How do I calculate the weight of a TMT bar?
Use D² ÷ 162 kg per metre, where D is the diameter in mm. A 12 mm bar weighs about 0.888 kg per metre.
Are TMT bars sold by piece or by weight?
Bulk orders are priced per ton by weight. Shops sometimes quote per piece for small quantities, but the invoice should still show weight.
What is a mill test certificate?
A report from the steel plant showing the chemical composition and strength of the batch. Ask for it with bulk orders.
