What does RHS steel mean ?

RHS stands for Rectangular Hollow Section, that is rectangular steel pipe.

We also have square hollow section steel pipe, according to standard: ASTM A500 , EN10219 , JIS G3466 , GB/T6728 cold formed square and rectangular steel pipe.

RHS usually refers to rectangular hollow steel in steel, which is the abbreviation of Rectangular Hollow Section. This steel is hollow and has a rectangular cross-section and is often used in construction and structural engineering.

Shape: Hollow steel pipe with rectangular or rectangular cross section, with four corners likely rounded corners (depending on manufacturing standards).

Features: Light weight, strong bending and torsional resistance, suitable as structural support or frame material.

Common application scenarios

1. Building structure

Used to build beams, columns or frames of houses, bridges, and factories.


2. Machinery manufacturing

As equipment brackets, conveyor tracks, etc.


3. Furniture/decoration

The skeleton material of modern style furniture (such as metal tables and chairs, shelves).


4. Vehicles and ships

Parts that require lightweight design, such as car bodies and hulls.
