Aluminium Hollow Sections

Aluminium Hollow Sections


Aluminium hollow sections, also known as aluminium box sections, are extruded hollow tubes with sharp edges. Aluminium hollow sections are categorized into three main types: rectangular hollow sections (RHS), square hollow sections (SHS) and circular hollow sections (CHS). Each type of hollow section has its own attributes and serves a specific purpose. Aluminium hollow section offers an ideal balance between strength, functionality and aesthetic appearance for a multitude of applications that require all three aspects. Aluminium hollow sections have superior corrosion resistance and weight-reducing characteristics, which make them perfect for use in construction and industrial applications.


Uses of aluminium hollow sections include architectural and construction applications, frames, handrails, general fabrication, building supports, windows, marine, automotive, fencing and transportation.


Two of the common grades of aluminium hollow sections are AA6061 and AA6063. Aluminium grade 6061 is one of the most widely used aluminium alloy for aluminium hollow sections or extrusions. AA6061 has superior strength and corrosion resistance properties with good machinability and can be easily anodised and bent to suit different needs. Commons uses for aluminium grade 6061 include transportation components, machinery, industrial equipment and consumer durables.

Aluminium alloy 6063 is another widely used medium strength alloy, which has generally good mechanical properties, is heat treatable and is readily suited to welding. Aluminium 6063 is therefore considered to have some of the best all-around extruding properties. AA6063 has a good surface finish, is corrosion-resistant and can be anodized. Its strength, as extruded, is somewhat higher than that of 3003 and is used in the fabrication of intricate extrusions.

Common Grades, Sizes and Specifi­cations

Grades Width Thickness Length
AA6061 From 12.7mm From 1.5mm Up to 6000mm
AA6063 From 9.53mm From 0.8mm Up to 6000mm
AA6082 From 12.7mm From 1.5mm Up to 6000mm

Other aluminium hollow section grades and sizes are available upon request. You can request to cut your aluminium hollow sections to size.
