| Standard | EN10210-1 Hot finished structural hollow sections of non-alloy and fine grain steels Part 1: Technical delivery conditions Part 2: Tolerances, dimensions and sectional properties |
| Cold forming | Process is done at ambient temperature |
| Application | For Construction & Decoration, For General Engineering Purposes |
| Manufacture | Structural hollow sections are manufactured by seamless or by welding. Welded sections manufactured by contiuous process. Electric welded hollow sections are supplied without trimming the internal weld bead. |
| Delivery condition: | Qualities JR, J0, J2 and K2 - Hot finished Qualities N and NL - normalized. (normalized rolled) - for accelerated cooling +DC - for quenching and tempering +QT |
| Surface conditon | The hollow sections have a smooth surface corresponding to the manufacturing method used; bumps, cavities or shallow longitudinal grooves resulting from the manufacturing process are permissible, provided the thickness is within tolerance. |
| Element | Permissible maximum content in the cast analysis | Permissible deviation of the product analysis from specified limits for cast analysis % by mass |
