Hollow Sections - Box Sections

Rectangular Hollow Sections

Rectangular hollow section (RHS) is a steel tube with a rectangular cross-section which is commonly used in construction and engineering projects. RHS is also known as rectangular steel tubes or rectangular steel hollow sections. The sections are made by cold or hot-forming flat sheet steel into a rectangular shape and welding the edges together.

RHS are characterized by their high strength-to-weight ratio, as well as their aesthetic appeal and ability to be easily fabricated. They are available in a range of sizes and thicknesses to meet specific design requirements.

Cold-formed S275 is the standard grade of RHS, but you can also get these in Cold-formed S355 and Hot-Rolled S355. Increasing the grade specifications increases the strength of the section as well as the price. 

The sizes of RHS are specified by their outside dimensions, for example; 200x100x10. The first two dimensions are the height and width of the section, with the final dimension is the thickness of the wall. Each different section can be acquired in a variety of different wall thickness’

Square Hollow Sections

Square hollow section (SHS) is a steel tube with a square cross-section which is commonly used in construction and engineering projects. SHS is also known as square steel tubes or square steel hollow sections. The sections are made by cold or hot-forming flat sheet steel into a square shape and welding the edges together.

SHS are characterized by their high strength-to-weight ratio, as well as their aesthetic appeal and ability to be easily fabricated. They are available in a range of sizes and thicknesses to meet specific design requirements.

The corners of SHS are typically rounded, rather than sharp, to reduce stress concentrations and improve the overall strength of the section. 

Cold-formed S275 is the standard grade of SHS, but you can also get these in Cold-formed S355 and Hot-Rolled S355. Increasing the grade specifications increases the strength of the section as well as the price. 

The sizes of SHS are specified by their outside dimensions, for example; 100x100x10. The first two dimensions are the height and width of the section, with the final dimension is the thickness of the wall. Each different section can be acquired in a variety of different wall thickness’

Circular Hollow Sections

Circular hollow section (CHS) is a type of cold or hot-formed, welded steel tube that has a circular cross-section. CHS is commonly used in the construction and engineering industries due to its strength, durability, and aesthetic appeal. CHS can also be known as steel tube and circular steel tube

The circular shape of CHS provides several advantages, including ease of use in structural design, compatibility with other building materials, and a high strength-to-weight ratio. CHS are made by cold-forming flat sheet steel into a circular shape and welding the edges together.

CHS are available in a range of sizes and thicknesses to meet specific design requirements. The sizes of CHS are specified by their outside diameter, with common sizes ranging from 21.3 mm to 508 mm, and wall thicknesses ranging from 2.0 mm to 16 mm.

ERW & Seamless Tube

In addition to the above items we can also source ERW tube (Electric Resistance Welded) is a type of welded steel tube that is formed by rolling steel strip through a series of rollers to form a tube shape. The edges of the strip are then electrically resistance welded together, using either high-frequency or low-frequency electrical current. The welding process is achieved without the use of any filler material, resulting in a strong and durable seam. ERW steel tube is characterized by its straightness, uniformity, and high dimensional accuracy. 

We can also source Seamless Tube. Seamless steel tube is a type of steel tube that is formed without any seams or welded joints. It is produced by piercing a solid billet of steel with a mandrel to create a hollow tube. The tube is then further processed through a series of sizing and finishing operations to achieve the desired size and surface finish. The lack of a seam can prove useful when trying to slot other things inside of the tubing with  close tolerance.
