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.
In the case of steel products such as sections, bolts and fabricated steelwork the CE Marking demonstrates that the product complies with the relevant harmonized standard. [7] For steel structures the main harmonized standards are: Steel sections and plate – EN 10025-1; Hollow sections – EN 10219-1 and EN 10210-1; Pre-loadable bolts – EN ...
Therefore, a 152x152x23UC would be a column section (UC = universal column) of approximately 152 mm (6.0 in) depth, 152 mm width and weighing 23 kg/m (46 lb/yd) of length. [10] In Australia, these steel sections are commonly referred to as Universal Beams (UB) or Columns (UC). The designation for each is given as the approximate height of the ...
Before the introduction of BS 317, GH Scholes (Wylex) introduced (in 1926) an alternative three-pin plug [28] in three sizes, 5 A, 10 A and 15 A with a round earth pin and rectangular live and neutral pins. A fused 13 A version of this continued to be available after the introduction of BS 1363, illustrating that BS 546 was not used exclusively ...
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...

The only way to obtain the actual OD is to look it up in a reference table. For pipe sizes of NPS 14 inch (DN 350) and greater the NPS size is the actual diameter in inches and the DN size is equal to NPS times 25 (not 25.4) rounded to a convenient multiple of 50. For example, NPS 14 has an OD of 14 inches or 355.60 millimetres, and is ...
