A hot-rolled HSS-box section cut open with a bandsaw, demonstrating residual stress. 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.
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 ...

EN 10027-1 steel grade designation system. European standard steel grade names fall into two categories: [1] Steel specified by purpose of use and mechanical properties.
ASTM A500 is a standard specification published by the ASTM for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. It is the most commonly specified ASTM standard in the US for hollow structural sections.
(Values in bold face are exact.) 1 g/mm 2 equals exactly 1000 kg/m 2.; 1 kg/cm 2 equals exactly 10 000 kg/m 2.; With the pound and inch legally defined as 0.453 592 37 kg and 0.0254 m respectively, it follows that the (mass) pounds per square inch is approximately:
This specification covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1⁄8 to NPS 26 [DN 6 to DN 650] (Note 1), inclusive, with nominal wall thickness (Note 2) as given in Table X2.2 and Table X2.3.
The British, European and International standard for hot-dip galvanizing is BS EN ISO 1461, which specifies a minimum coating thickness to be applied to steel in relation to the steels section thickness e.g. a steel fabrication with a section size thicker than 6 mm shall have a minimum galvanized coating thickness of 85 μm.
