EN 10219 cold formed welded structural hollow sections are load-bearing steel tubes manufactured by cold-forming strip/plate into a closed section and producing a continuous weld (commonly ERW/HF). EN 10219-2 governs tolerances, dimensions, and sectional properties, while steel grades and delivery requirements are defined in EN 10219-1.
Typical grade options (examples): S235JRH, S275J0H, S355J2H (non-alloy structural steels) and S420MH, S460MH (fine-grain, thermomechanically rolled steels).
Product forms: CHS (round), SHS (square), RHS (rectangular), EHS (elliptical)
EN 10219-2 scope (size capability):
Wall thickness: up to 40 mm
Circular OD: up to 2,500 mm
Square: up to 500 × 500 mm
Rectangular: up to 500 × 300 mm
Elliptical: up to 480 × 240 mm
Supply condition: as-welded/cold-formed (per EN 10219 family), optional surface protection (black/oiled/painted/galvanized), cut-to-length available
Typical lengths: 6 m / 12 m, or as required by drawings and packing rules
Dimensional consistency for fabrication: EN 10219-2 defines tolerances and sectional-property calculation rules used in structural design and detailing.
High strength-to-weight ratio: closed hollow sections provide excellent buckling resistance and clean load paths for frames and trusses.
Weldable, production-friendly: suited for automated cutting, drilling, and welding when ordered with the right toughness and certificate level.
We support heat/batch traceability with EN 10204 Type 3.1 inspection documentation when specified, including actual chemical/mechanical results and clear linkage to delivered goods. For EU construction supply chains, documentation and traceability are commonly tied to CE/EN 1090 execution routes; reputable producers explicitly reference 3.1 documentation and structural suitability in their DoP/AVCP workflow.
For structural hollow sections, weld quality is managed through controlled welding parameters plus inspection. Full-length weld NDT is commonly specified by leading producers for EN 10219 products, and additional NDT methods (e.g., radiographic testing of weld seams) are standardized in ISO tube-testing practices. We can align inspection scope (visual, UT/RT where required) with project specs.
EN 10219-2 is specifically written to control dimension and shape tolerances and provides the basis for sectional properties used in structural design. When you build to this tolerance system, fit-up improves (less rework on connection plates, better squareness/straightness targets, more predictable end-prep and assembly).
