A hollow structural section (HSS) is a type of metal profile with a hollow cross section. The term is used predominantly in the United States, or other countries which follow US construction or engineering terminology. HSS members can be circular, square, or rectangular sections, although other shapes such as elliptical are also available.
Corrugated galvanised iron (CGI) or steel, colloquially corrugated iron (near universal), wriggly tin (taken from UK military slang), pailing (in Caribbean English), corrugated sheet metal (in North America), zinc (in Cyprus and Nigeria) or custom orb / corro sheet (Australia), is a building material composed of sheets of hot-dip galvanised ...

Cross section diagram of standard strut channel. Basic strut channel comes in the open box section 1 + 5 ⁄ 8 in (41 mm) square. A half height 1 + 5 ⁄ 8 in × 13 ⁄ 16 in (41 mm × 21 mm) version is also available, used mostly where mounted directly to a wall as it has significantly less stiffness and ability to carry loads across an open space or brace.
EN10219-1 specifies the technical delivery conditions for cold formed welded structural hollow sections of circular, square or rectangular forms and applies to structural hollow sections formed cold without subsequent heat treatment. Requirements for S275JOH pipe tolerances, dimensions and sectional s275 pipe properties are contained in EN 10219-2.
A box truss is a structure composed of three or more chords connected by transverse and/or diagonal structural elements. [1] Application
