If you are searching for square tube price per kg in India, you have landed on the right page. Whether you are a contractor, fabricator, builder, or just someone planning a construction project, understanding square tube pricing helps you budget accurately and avoid overpaying.
In this guide we cover everything — what square tubes are, factors that affect price, current rate ranges, and where to buy them smartly.
What is a Square Tube?
A square tube is a hollow steel section with equal width and height on all four sides. It is widely used in construction, furniture making, gates, grills, sheds, industrial fabrication, and structural frameworks.
Square tubes are measured by their outer dimensions and wall thickness — for example 25x25x2mm or 50x50x3mm. The heavier the wall thickness, the more it weighs per metre, and the higher the cost per kg.
Square Tube Price Per Kg in India — Current Rate Range
The square tube price per kg in India generally ranges between:
Rs. 55 to Rs. 80 per kg for mild steel square tubes
Rs. 90 to Rs. 130 per kg for galvanized square tubes
Rs. 180 to Rs. 350 per kg for stainless steel square tubes
These are indicative rates for 2025. Actual prices vary based on brand, city, quantity, and steel market conditions.
Factors That Affect Square Tube Price Per Kg
1. Material Grade
Mild steel is the most affordable. Galvanized steel costs more because of the zinc coating. Stainless steel is the most expensive due to its corrosion resistance and alloy content.
2. Wall Thickness
Thicker walls mean more steel per metre which increases weight and cost. A 25x25x1.6mm tube weighs less per metre than a 25x25x3mm tube, so understanding thickness is key when comparing square tube price per kg.
3. Size of the Tube
Larger section sizes like 100x100mm cost more in total per piece but the per kg rate may be similar or slightly lower for bulk sizes.
4. Brand and Manufacturer
Brands like Tata Steel, SAIL, JSW, and Jindal command a premium. Local or secondary market steel is cheaper but quality may vary.
5. Market Conditions
Steel prices are linked to global iron ore and coal prices. They fluctuate monthly. Always check current rates before finalizing your purchase.
6. Quantity
Buying in bulk — one tonne or more — always gets you a better square tube price per kgcompared to buying a few pieces.
7. City and Location
Prices in Mumbai, Delhi, and Hyderabad differ. Transportation and local taxes affect the final landed cost.

Where to Buy Square Tubes in India
Local Steel Dealers — Most cities have a steel market or industrial area with multiple dealers. You can negotiate and compare rates easily.
Online Platforms — Websites like IndiaMART, TradeIndia, and Steel360 list suppliers with price ranges. Good for comparing before visiting dealers.
Direct from Mills — For large orders above 5 tonnes, buying directly from manufacturers like Tata or JSW saves cost.

Mild Steel Square Tube — Most Common Sizes and Prices
20 x 20 x 2mm MS Square Tube — Rs. 58 to Rs. 65 per kg
25 x 25 x 2mm MS Square Tube — Rs. 58 to Rs. 65 per kg
40 x 40 x 2mm MS Square Tube — Rs. 56 to Rs. 63 per kg
50 x 50 x 2mm MS Square Tube — Rs. 55 to Rs. 62 per kg
50 x 50 x 3mm MS Square Tube — Rs. 55 to Rs. 62 per kg
75 x 75 x 3mm MS Square Tube — Rs. 54 to Rs. 60 per kg

How to Calculate Total Cost
Total Cost = Weight per metre x Length needed x Price per kg
Example: You need 50 metres of 50x50x3mm square tube. Weight per metre = 4.29 kg. Total weight = 50 x 4.29 = 214.5 kg. At Rs. 60 per kg = Rs. 12,870 total cost.
Always add 5 to 10 percent for wastage and cutting.
Square Tube Uses in Construction

Furniture Frames — Office chairs, tables, racks, and shelving units use square tubes for structural support.
Sheds and Warehouses — Industrial sheds use large section square tubes for columns and roof trusses.

Tips to Get the Best Square Tube Price Per Kg
Compare at least 3 dealers before buying. Prices can vary by Rs. 3 to 5 per kg between dealers in the same city.
Buy in full bundles — Steel comes in standard bundles. Cutting a bundle attracts extra charges. Buying full bundles saves money.
Check the weight yourself — Always weigh your purchase at the shop. You are paying per kg so accuracy matters.
Ask for mill test certificate — For structural projects, ask for MTC to confirm grade and quality.
Time your purchase — Steel prices dip during monsoon when construction slows down. If you can wait, you may get a better square tube price per kg.
