This European Standard specifies the technical delivery conditions for welded cold sized steel tubes of square and rectangular cross section for precision applications. Tubes according to this document are characterized 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.<\/p>\n
