MS Square Pipe Weight Chart 2026: Weight, Calculation, Formula, Sizes & Price
Last Updated: September 2026
The MS Square Pipe Weight Chart 2026 is an important reference for engineers, fabricators, contractors, architects, builders, and procurement professionals who need to estimate the weight of mild steel square pipes. Accurate weight information helps in material planning, structural calculations, transportation estimation, project costing, and purchasing decisions.
MS square pipes, also called Square Hollow Sections (SHS), are hollow steel profiles manufactured with equal outside dimensions on all four sides. Their weight mainly depends on the outside size, wall thickness, steel density, manufacturing tolerances, and pipe length.
This guide explains MS square pipe weight, the calculation formula, common sizes, weight per metre and foot, order-weight calculations, pricing factors, IS 4923 considerations, and practical buying guidelines.

How to Calculate MS Square Pipe Weight
The weight of an MS square pipe can be determined from its cross-sectional area and the density of steel.
MS Square Pipe Weight Formula
Weight (kg/m) = Cross-sectional Area × Steel Density
For a square hollow section:
Cross-sectional Area = Outer Area − Inner Area
Therefore, the commonly used formula is:
Weight = [A² − (A − 2T)²] × 7850
Where:
- A = outside square dimension in metres
- T = wall thickness in metres
- 7850 kg/m³ = nominal density of mild steel
This formula is useful when the required size is not available in a standard weight table.
Example: 40 × 40 × 3 mm MS Square Pipe
Consider an MS square pipe measuring 40 × 40 mm with a 3 mm wall thickness.
Outside dimension:
A = 40 mm = 0.040 m
Wall thickness:
T = 3 mm = 0.003 m
Inside dimension:
40 − (2 × 3) = 34 mm
Cross-sectional area:
40² − 34² = 1600 − 1156 = 444 mm²
Converting to square metres:
444 mm² = 0.000444 m²
Weight:
0.000444 × 7850 ≈ 3.49 kg/m
Therefore, the theoretical weight of a 40 × 40 × 3 mm MS square pipe is approximately 3.49 kg per metre.
MS Square Pipe Weight Per Foot
Some construction and fabrication projects use feet instead of metres for measurements. To convert the weight from kg/m to kg/ft, use:
Weight per foot = Weight per metre ÷ 3.28084
For a pipe weighing 3.49 kg/m:
3.49 ÷ 3.28084 ≈ 1.06 kg/ft
For a standard 6-metre pipe:
3.49 × 6 = 20.94 kg
Therefore, one 6-metre 40 × 40 × 3 mm square pipe has an estimated theoretical weight of approximately 20.94 kg.
How to Calculate the Weight of a Complete Order
Calculating the total order weight is useful for procurement, transportation, handling, and project costing.
For example, assume a project requires:
100 pieces of 50 × 50 × 4 mm MS Square Pipe, with each pipe measuring 6 metres.
The approximate weight is:
5.79 kg/m
Weight of one 6-metre pipe:
5.79 × 6 = 34.74 kg
Weight of 100 pipes:
34.74 × 100 = 3,474 kg
Therefore, the estimated order weight is approximately:
3.474 metric tonnes (MT)
This approach allows buyers to estimate material quantities and transportation requirements before placing an order.
MS Square Pipe Price in 2026
MS square pipe prices are influenced by several factors, so the price per kilogram should not be considered fixed. Steel raw-material costs, market demand, pipe dimensions, wall thickness, quantity, manufacturing process, taxes, freight, and delivery location can all affect the final quotation.
A basic calculation for estimating material cost is:
Estimated Material Cost = Total Weight × Applicable Price per kg
For example, if the calculated order weight is 3,474 kg, multiply this quantity by the supplier's current quoted price per kilogram.
Since steel prices can change according to market conditions, buyers should obtain a current quotation before making a commercial purchase.
Factors Affecting MS Square Pipe Price
- Raw material and steel market prices
- Pipe outside dimensions
- Wall thickness
- Required grade and specification
- Order quantity
- Manufacturing process
- Surface condition
- Testing and certification
- GST and applicable taxes
- Packing requirements
- Freight charges
- Delivery location
- Market availability
Why Wall Thickness Matters
Wall thickness directly affects the weight and structural characteristics of an MS square pipe. Increasing the thickness increases the cross-sectional area and consequently increases the weight per metre.
A thicker wall can also provide greater structural stiffness, improved resistance to deformation, and increased load-carrying capability. However, selecting a pipe simply because it has a higher weight is not an appropriate engineering method.
The required wall thickness should be determined according to the project's structural calculations, loading conditions, design requirements, connection details, environmental conditions, and applicable standards.
IS 4923 MS Square Hollow Sections
IS 4923 is an important Indian specification associated with steel hollow sections used for structural purposes.
When ordering MS square pipes for structural applications, buyers should specify the required:
- Outside dimensions
- Wall thickness
- Steel grade
- Applicable standard
- Pipe length
- Quantity
- Testing requirements
- Surface condition
- Certification requirements
For critical projects, a Material Test Certificate (MTC) may also be required to verify relevant chemical and mechanical properties.
Theoretical Weight vs Actual Weight
An MS Square Pipe Weight Chart generally provides theoretical or calculated weight. The actual weight of manufactured pipes may vary within applicable manufacturing tolerances.
Differences can result from:
- Wall-thickness tolerances
- Outside-dimension tolerances
- Corner radius
- Manufacturing method
- Length tolerances
- Surface condition
- Mill practices
- Measurement methods
Therefore, theoretical weight should primarily be used for estimation, preliminary costing, inventory planning, and project calculations. For final commercial reconciliation, buyers should consider the actual supplied weight and agreed purchasing terms.
Applications of MS Square Pipes
MS square pipes are widely used in construction, fabrication, engineering, infrastructure, and industrial projects. Their hollow design provides a practical combination of strength, material efficiency, fabrication flexibility, and manageable weight.
Common applications include:
- Structural frameworks
- Industrial sheds
- Warehouse structures
- Staircases
- Railings and handrails
- Gates and fencing
- Machinery frames
- Agricultural equipment
- Automotive structures
- Construction supports
- Solar mounting structures
- Furniture fabrication
- General engineering work
The correct size and wall thickness should always be selected according to the intended load, span, connections, environmental conditions, and engineering requirements.
How to Select the Right MS Square Pipe
Before purchasing an MS square pipe, consider more than just the outside size.
1. Confirm the dimensions: Select the required square size, such as 25 × 25, 40 × 40, 50 × 50, 100 × 100 mm, or another specification.
2. Select wall thickness: Choose the thickness according to structural and project requirements.
3. Confirm the standard: Clearly specify the required IS or project standard.
4. Check documentation: For important applications, request the applicable MTC and testing documents.
5. Calculate total weight: Use the kg/m value to estimate the total material requirement.
6. Compare quotations: Evaluate price, specifications, certification, freight, taxes, delivery, and actual weight rather than comparing only the price per kilogram.
