What is the difference between square tube and rectangular tube?
Date:2023-02-21View:1446Tags:SHS stee(square tube),RHS steel(rectangular tube)
SHS steel stands for square tube. RHS steel stands for rectangular tube. These two specific types of steel hollow sections are designed to provide a combination of strength and functionality which makes them suitable for a wide variety of applications.
SHS is square in shape and can be welded or joined to flat surfaces as easily as RHS steel. SHS can be used in applications where strength, functionality and aesthetic appeal is required.
RHS is rectangular in shape and requires minimal preparation prior to joining or welding to flat surfaces. This feature, together with its structural strength, makes RHS steel an economical and practical choice for the construction industry and civil engineering projects in all areas.
What lengths does RHS and SHS steel come in?
Painted square hollow section steel (SHS) is available in a variety of lengths. SHS is also available in a range of standard sizes from 25x25mm to 400x400mm in square dimensions and 50x25mm to 400x300mm in rectangular dimensions.
Lengths of SHS range from 6.5mx 8.0m and 12.0m, and are also not limited to these lengths. Thickness ranges from 2.0mm to 16.0mm. The specifications for SHS are listed in the InfraBuild Know Your Steel guide.
Painted rectangular hollow section (RHS) steel can be supplied in many different lengths, as per above. If you require lengths of painted structural tube not listed in our product tables, we offer a cut to length service. We also provide a number of other processing services that can be tailored to meet your specific requirements, including drilling, mitre cutting and stamping of all types of structural steel tubing we distribute in Australia.
Which is stronger SHS or RHS steel?
The question of which is stronger, SHS or RHS depends on a variety of different factors. Factors to take into consideration include the dimensions of the tubing under evaluation, the thickness of the section’s walls and the type of steel from which each section has been formed.
However, if we are comparing a length of RHS steel with the smallest dimension equal to or greater than the side dimension of a length of SHS steel, manufactured from the same materials and using the same process, the RHS steel will always prove to be stronger when an equal load is applied to each length, from any direction or orientation.
As a point of interest, while RHS and SHS steel are both stronger than circular hollow section (CHS) steel in applications where the direction of an applied load or force is known in advance, CHS steel actually performs better when the direction of any applied force or load is unknown at the design stage.
What is RHS and SHS steel used for?
The RHS and SHS structural steel tubing InfraBuild Steel Centre manufactures, distributes and supplies around Australia is used across a wide range of environments and sectors. Environments and sectors include engineering construction, residential construction, commercial construction, mining, logistics, manufacturing and agriculture industries. Applications where SHS and RHS steel are commonly used include welded steel frames for furniture, automotive chassis, and machinery and construction projects. Rectangular and square hollow section steel is also often used for beams in architectural applications.
Painted Structural Steel Tube – SHS & RHS
Painted SHS (square hollow sections) and RHS (rectangular hollow sections) are high-strength cold-formed hollow steel sections that are primer painted for protection during storage and handling. DuraPrimed primer paint for tubular steel products has been developed specifically to save users time and money without compromising quality.
All DuraPrimed sections supplied by InfraBuild Steel Centre are available as C450PLUS structural tube. C450PLUS structural tube achieves the highest-strength grade, C450L0, of AS/NZS 1163, while maintaining the elongation and formability of C350L0, providing no loss of ductility or workability.
