๐ญ Industrial (Udyog) Applications of MS Square Pipes
MS square pipes are widely used across Udyog sectors due to their structural strength and cost-efficiency:
๐ง Key Applications in Industry:
-
Udyog Sheds & Warehouses – Pillars, trusses, and rafter systems
-
Machinery Frameworks – Ideal for automated systems and conveyor supports
-
Structural Fabrication – Gates, fencing, and grillwork
-
Pre-Engineered Buildings (PEBs) – Base structure and framing
-
Agricultural Equipment Manufacturing
These pipes offer high weldability and resistance to vibration, making them reliable in heavy-duty and high-performance Udyog applications.

๐ฆ How to Choose the Right MS Square Pipe for Your Industry
๐ Factors to Consider:
-
Load-bearing requirements
-
Corrosion protection needs (galvanized or coated)
-
Cutting & welding compatibility
-
Wall thickness vs. cost efficiency
Use 3mm–6mm thickness for structural works and 1.6mm–2.5mm for light fabrication like furniture or decorative work.
๐งพ MS Square Pipe Weight Chart (Sample)
| Size (mm x mm) | Thickness (mm) | Weight (kg/m) |
|---|
| 25 x 25 | 2.0 | 1.50 |
| 40 x 40 | 3.0 | 3.45 |
| 50 x 50 | 4.0 | 5.48 |
