How to Select the Right Hollow Section Pipes for Your Project?

Selecting the right hollow section pipes for your project can be difficult. You need to carefully consider various criteria like the required size, shape, material used, load capacity and other technical aspects to make sure that you select the most appropriate type of pipe for your project. An essential factor is ensuring that your chosen pipe satisfies all applicable safety standards and codes. Moreover, you should also consider factors such as cost efficiency and required delivery time before selecting a particular pipeline material. These tips will help you pick the right hollow section pipes for your project!

What are Hollow Section Pipes?

A Hollow Section Pipe, also referred to as a hollow structural section or HSS pipe, is a type of metal pipe formed into a hollow tubular shape. HSS pipes are typically made from steel, although they can be constructed from aluminium and other materials. The advantages of using HSS pipes compared to solid wall pipes include their higher strength-to-weight ratio, greater flexibility in design, increased corrosion resistance and easier fabrication. They can also be used in applications requiring fluids or electrical current transmissions, such as telecommunications towers and industrial machinery.

Way to Select the Right Hollow Section Pipes

Consider the Purpose of Your Project:

The first and most important factor to consider when selecting hollow section pipes for your project is their purpose. Will you use them to build structures, pipelines, or a ship’s hull? Each application has different dimensions, steel grade, and seaworthiness requirements. For example, if you’re building a ship’s hull, you must choose pipes with high seaworthiness and corrosion resistance. On the other hand, if you’re constructing a building, you will be more focused on the dimensions and load-bearing capacity of the pipes.


The next factor to consider is the dimensions of the hollow section pipes. The outside diameter, wall thickness, and length of the pipes are crucial for determining their load-bearing capacity and suitability for your project. The standard dimensions for hollow section pipes are typically between 12mm and 500mm in outside diameter and between 0.5mm and 20mm in wall thickness. However, custom sizes may be available on request. Be sure to specify the dimensions you need when ordering the pipes.

Steel Grade:

The steel grade is another important factor when selecting hollow section pipes for your project. The steel grade determines the pipes’ strength, durability, and corrosion resistance. The most common steel grades for hollow section pipes are S355, S235, and S420. S355 and S420 offer the highest strength and durability but are more expensive than S235. Choose the appropriate steel grade based on your project’s requirements.


If your project involves submerged or marine applications, the pipes’ seaworthiness is an important factor to consider. Seaworthiness refers to the pipes’ ability to withstand corrosion and other marine conditions. Hollow-section pipes with high seaworthiness are typically coated with anti-corrosive materials such as zinc or epoxy. When selecting pipes for marine applications, choose pipes with a high seaworthiness rating.


Weight is the last factor to consider when selecting hollow section pipes for your project. Lightweight pipes are easier to handle and transport but may not be suitable for heavy load-bearing applications. On the other hand, heavyweight pipes have higher load-bearing capacity, but they may be more difficult to handle and transport. Choose the appropriate weight for your project based on your requirements.


Selecting the right hollow section pipes for your project requires careful consideration of various factors, such as dimensions, steel grade, seaworthiness, and weight. The purpose of your project is the most crucial factor to consider when selecting pipes, followed by dimensions, steel grade, and seaworthiness. When ordering pipes, specify your requirements to ensure you get the right product for your project. With the right hollow section pipes, you can ensure that your project is built to last and meets all safety and performance requirements.
