EN10219 hollow section

 

The EN10219 standard specifies the technical delivery conditions for high strength and weather resistant electric welded and submerged arc welded cold formed steel structural hollow sections of circular,square, rectangular or elliptical forms and formed cold without subsequent heat treatment other than the heat treatment of the weld line.

Details of the product form:
CFCHS = cold formed circular hollow section;
CFRHS = cold formed square or rectangular hollow section;

Thankfully, YOUFA STEEL PIPE has an EN10219 standard certificate and our EN10219 consistently follows this standard!

  • a  The deoxidation method is designated as follows:

         FF: Fully killed steel containing nitrogen binding elements in amounts sufficient to bind available nitrogen (e.g. min. 0,020 % total Al or 0,015 % soluble Al).

  • b  The maximum value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0,020 % with a minimum Al/N ratio of 2:1, or if sufficient other N-binding elements are present. The N-binding elements shall be recorded in the Inspection Document.

  • a  The impact properties are verified only when Option 1.3 is specified.
  • b  For thicknesses > 3 mm and section sizes D/T < 15 (round) and (B+H)/2T < 12,5 (square and rectangular) the minimum elongation is reduced by 2. For thicknesses ≤ 3 mm the minimum value for elongation is 17 %.
  • c  For section sizes D/T< 15(circular) and (B+H)/2T< 12,5(square and rectangular) the minimum elongation is reduced by 2.
  • d  For thicknesses < 3 mm see 9.2.2.
  • e  For impact properties for reduced section test pieces see 6.7.2.
  • f  This value corresponds to 27J at-30 °C (see EN 1993-1-1).
