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.

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 EN10219-1 9.2.2.

e. For impact properties for reduced section test pieces see 6.7.2.

FAQ

Q: What is EN10219-1 welded hollow section mainly used for?

A: It is a welded structural hollow tube for construction projects. Commonly used for building frames, support brackets, guardrails and machinery bases.

Q: What material grades can you supply?

A: We mainly offer S235JR, S275JR and S355JR. We can pick proper grades based on your project load requirement.

Q: What is the difference between EN10219-1 and seamless hollow section?

A: EN10219-1 is welded tube. It is cost-effective for general structural use, while seamless types are chosen for high pressure working conditions.

Q: Can you provide cutting and surface treatment service?

A: Yes. We can cut to your required length, and do galvanizing, painting or other surface finishes as requested.
