DIN EN 10210-1:
Hot finished structural hollow sections of non-alloy and fine grain steels
Process is done at ambient temperature
Structural hollow section manufacturing process:
Structural hollow sections are manufactured by seamless or by welding.
Welded sections manufactured by continuous process.
Electric welded hollow sections are supplied without trimming the internal weld bead.
Qualities JR, J0, J2 and K2 - Hot finished
Qualities N and NL - normalized. (normalized rolled)
- for accelerated cooling +DC
- for quenching and tempering +QT
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.
End: Square cut
