BS EN 10305-5:2010

BS EN 10305-5 is the standard that specifies the technical delivery conditions for welded cold sized steel tubes of square and rectangular cross section for precision applications.

Tubes according to BS EN 10305 are characterised by having precisely defined tolerances on dimension and a specified maximum surface roughness. Typical fields of application are in the automotive, furniture and general engineering industries.

BS EN 10305 Steel tubes for precision applications. Technical delivery conditions, consists of the following parts:

• Part 1: Seamless cold drawn tubes
• Part 2: Welded cold drawn tubes
