When it comes to construction and engineering projects, choosing the right materials is crucial. One such material widely used in various applications is MS Square Pipe. MS square pipes, also known as mild steel square pipes, offer structural stability and durability. However, understanding the size specifications of MS square pipes is essential to ensure the success of your project. In this article, we will delve into the details of MS square pipe sizes, covering their dimensions, applications, and considerations. So, let’s explore the world of MS square pipes together.

What are MS Square Pipes?

MS square pipes are hollow, rectangular tubes made from mild steel, a low-carbon steel with excellent strength and versatility. These pipes are known for their durability and cost-effectiveness, making them a popular choice in various industries such as construction, automotive, furniture, and more. MS square pipes offer structural stability and can withstand heavy loads, making them ideal for applications that require strength and reliability.

Understanding MS Square Pipe Sizes:

MS square pipes come in a range of sizes to accommodate different requirements. The size of an MS square pipe is determined by its dimensions, including the outer diameter, wall thickness, and length. Here are the key components that define the size of an MS square pipe:

Outer Diameter:

The outer diameter of an MS square pipe refers to the measurement across its widest point. It is an essential factor to consider when determining the size of the pipe. Common outer diameter sizes for MS square pipes range from 10mm to 500mm, catering to a wide range of applications.

Wall Thickness:

The wall thickness of an MS square pipe refers to the measurement of the pipe’s walls. It affects the pipe’s strength, load-bearing capacity, and overall structural integrity. MS square pipes come in various wall thicknesses, typically ranging from 0.5mm to 20mm. Choosing the appropriate wall thickness depends on the specific application and the amount of load the pipe needs to bear.


The length of an MS square pipe indicates its overall size and is an important consideration during construction or fabrication. The standard length of MS square pipes is typically 6 meters or 20 feet. However, customized lengths can be obtained based on project requirements. It’s worth noting that longer lengths may require additional support to maintain stability.

Applications of MS Square Pipes:

MS square pipes find wide-ranging applications across various industries. Some common applications include:

  1. Construction: MS square pipes are extensively used in building structures, frameworks, columns, and beams. Their strength and durability make them suitable for supporting heavy loads and providing stability to structures.
  2. Infrastructure: MS square pipes play a vital role in infrastructure projects, such as bridges, flyovers, and road barriers. Their robustness and resistance to environmental factors make them a reliable choice for such applications.
  3. Furniture: MS square pipes are used in the manufacturing of furniture, including tables, chairs, racks, and shelves. Their versatility, ease of fabrication, and cost-effectiveness make them popular in the furniture industry.
  4. Automotive: MS square pipes find applications in the automotive sector, particularly in the fabrication of vehicle frames, chassis, and roll cages. Their strength and impact resistance contribute to the safety and structural integrity of vehicles.

Considerations When Choosing MS Square Pipe Sizes:

Selecting the right size of MS square pipes requires careful consideration. Here are a few factors to keep in mind:

  1. Application: Determine the intended purpose of the MS square pipes and consider the load-bearing requirements, structural stability, and environmental factors.
  2. Structural Design: Consult with a structural engineer or a qualified professional to ensure the chosen size of MS square pipes aligns with the overall structural design and meets safety standards.
  3. Material Availability: Consider the availability of MS square pipes in the required sizes from reliable suppliers. This ensures smooth procurement and timely completion of your project.


Understanding the size specifications of MS square pipes is crucial for any construction or engineering project. By considering the outer diameter, wall thickness, and length, you can select the appropriate size that meets your specific requirements. MS square pipes offer strength, durability, and versatility, making them a preferred choice across various industries. Remember to consider the application and consult with experts to ensure the best fit for your project. With this knowledge, you are now equipped to make informed decisions when it comes to utilizing MS square pipes in your next endeavor.
