The Advantages of Cold-Formed RHS Pipes

If you’re in the market for steel pipe, one of the most important decisions you’ll have to make is what type to buy: cold-formed RHS (rectangular hollow section) or hot-finished? Each option has its benefits and drawbacks, but getting the right one for your specific needs is essential. In this blog post, we look at why investing in cold-formed RHS pipes offers numerous advantages over hot-finished options. From cost savings to better load-carrying capacity, find out why they remain popular for those on a budget without sacrificing quality.

What are RHS Pipes?

RHS pipes, which stand for Rectangular Hollow Section Pipes, are a type of structural pipe typically used in the construction industry. These pipes are hollowed from steel to create an L-shape with two parallel walls. This type of pipe is often used for making frames and structures due to its strength and durability compared to other piping materials. It also offers a wide range of architectural possibilities through its unique design and is often chosen over traditional materials due to its value when it comes to cost savings.

Benefits of Cold-Formed RHS Pipes

Superior Strength and Durability

RHS pipes stand for Rectangular Hollow Structural Sections, offering superior strength and durability thanks to their unique rectangular shape. They are made from cold-formed steel, which is very strong and lightweight, allowing it to be used in a range of applications such as sports stadiums, bridges, industrial buildings and more. The structure of these pipes creates an ideal load-bearing capacity, making them highly durable as well. Additionally, they are easy to install with low construction costs compared to other pipe materials like concrete or cast iron. Their uniform cross-section also provides excellent resistance against torsion stress, making them even more reliable for long-term usage.


Yes, RHS pipes are cost-effective, and the price depends on the size and grade of material used. Generally, they come in a range of sizes from 10mm to 200mm with 6-meter lengths and galvanized steel grades ranging from 250 to 500MPa yield strength. They have good strength-to-weight ratios, are resistant to corrosion, can be bent without loss of structural integrity and require minimal maintenance. Therefore, using RHS pipes will significantly reduce material costs while allowing for flexibility in installation locations.

Improved Aesthetics

RHS (Rectangular Hollow Section) pipes are often used in construction projects for improved aesthetics. They offer a more modern, contemporary appearance compared to traditional round pipes. Furthermore, the streamlined shape makes them easier to fit between objects or join together for larger structures. As a result, it is increasingly becoming an option for architects and engineers when planning buildings of all kinds – from tall skyscrapers to small sheds!

Greater Design Flexibility

RHS pipes offer greater design flexibility than other types due to their wide range of sizes, shapes and wall thicknesses. They are suitable for many applications such as water and gas supply, heating systems, industrial uses, sewage/drainage systems, etc. This can make them easier to deal with in constrained spaces or difficult terrains since they can be customized according to the user’s needs. Additionally, the welding process is relatively simpler as there is no need for special corner pieces due to their rectangular shape. The strength of the pipe makes it more resistant to corrosion, resulting in longer service life and cost-effectiveness due to higher manufacturing throughput levels.


Overall, the advantages of cold-formed RHS pipes over hot-finished pipes are clear. These pipes offer superior strength and durability, cost-effectiveness, improved aesthetics, and greater design flexibility. Therefore, it’s essential to consider cold-formed RHS pipes for your next construction or industrial application.
