The term RHS stands for Rectangular Hollow Section.
SHS stands for Square Hollow Section.
Less known is the term CHS, this stands for Circular Hollow Section.
In the world of engineering and construction, the acronyms RHS, SHS and CHS are often used. This is most common in the United Kingdom and associated countries, including Australia and New Zealand.
These terms are widely used to describe mild steel; however, they can also be translated for stainless steel and aluminium engineering and construction by engineers who are familiar with the terminology.
Rectangular Hollow Section is a rectangular steel profile with a rectangular hollow cross-section throughout its length, used in a wide variety of construction and engineering projects. Rectangular Hollow Sections (RHS) are also known as cold formed hollow section or box section.
Youfa supplies a wide range of rectangular hollow section specifications to nearly 100 countries and regions. Youfa brand RHS hollow sections are certified with ISO 9001, ISO 18001, FPC and CE, complying with JIS G3466, ASTM A500 and EN10219.

Square Hollow Sections (SHS), also known as cold formed hollow section or box section, are one of the most versatile building materials in the construction industry. Generally available in 5.8 metre and 6 metre lengths in Grade A Grade B, S235 S195; Based on large order quantity, other lengths and Grade C , S355 or other grades are available. For your information Kg/m refers to the Kilograms per Metre of the section, as an example a 6.0 Metre length of 50 x 50 x 3mm (SHS) Square Steel Hollow Section (4.49 Kg/m) theoretical weight would be (6 x 4.49) 26.94 Kg’s Total.
Youfa Steel Pipe factories distribute and manufacture square hollow section specifications ranging from 20x20mm to 400x400mm and mainly export to Southeast Asia, East Asia, Middle and South America, Middle East and Africa. Youfa brand SHS hollow sections are certified with ISO, FPC and CE, complying with JIS G3466, ASTM A500 and EN10219.
