The Advantages of Cold Formed Rectangular Hollow Sections

Posted by

Cold formed rectangular hollow sections (RHS) are becoming increasingly popular in construction due to their numerous benefits. They are made from cold-rolled steel, which results in a stronger, more durable material. In this blog post, we’ll discuss the advantages and uses of cold-formed RHS to help you understand why it could be the right choice for your next construction project.

What are Cold Formed Rectangular Hollow Sections?

Cold formed Rectangular Hollow Sections are structural steel profiles produced by cold-forming flat steel sheets or coils into rectangular shapes. This process involves bending and shaping the steel at room temperature without needing hot-rolling. Cold-formed RHS are characterized by their rectangular cross-sections with sharp, precise corners, as opposed to the rounded corners typically found in hot-rolled sections. These sections are widely used in construction and engineering applications due to their versatility, strength, and cost-effectiveness.

Cold-formed RHS can be employed for various purposes, including as load-bearing members in building frames, as components in infrastructure projects, and in constructing architectural elements like trusses and support structures. Their ability to withstand significant loads and their ease of fabrication makes them a popular choice in structural engineering and construction.

Advantages of Cold Formed Rectangular Hollow Sections

Strength and Durability

Cold formed RHS is stronger than hot-rolled steel, as the cold-rolled process makes the steel more resilient and stress-resistant. Cold formed RHS can endure greater pressure and weight, rendering it an ideal material for heavy-duty construction projects.


Cold formed RHS comes in various sizes, making it versatile and adaptable for different construction needs. It can be used for everything from building frameworks and support structures to creating artistic and ornamental designs.


Cold formed RHS is often more cost-effective than other materials. As it is made from a single sheet of steel, there are no joints or welds, which can reduce the construction cost. Additionally, the cold-formed process allows the steel to be used more efficiently, reducing waste and keeping costs low.

Energy Efficiency

Cold formed RHS is also an ideal choice for those looking to decrease their building’s energy usage. Due to its strength, it can be used to create more energy-efficient designs, such as thinner walls and longer spans, which can help reduce heating and cooling costs.

Uses of Rectangular Hollow Sections

Cold formed RHS can be used in a variety of industries. In construction, it is commonly used for buildings, such as warehouses and steel framing. It is also used in the automotive industry for structural components and in the manufacturing industry for equipment frames and support structures.


Cold formed rectangular hollow sections are an excellent choice for construction projects due to their strength, durability, versatility, cost-effectiveness, and energy efficiency. They can be used in a range of industries and for a variety of purposes. If you’re looking for an efficient, cost-effective, and environmentally friendly material, cold-formed RHS is worth considering. Talk to a professional in the industry to see if cold-formed RHS is right for your next project.
