Standards:
EN 10210-1 Hot finished structural hollow sections of non-alloy and fine grain structural steel.
DIN 17121 Seamless structural steel circular tubes for structural engineering purposes.
DIN 17124 Seamless circular tubes of fine grain steel for engineering purposes.
Steel grades:
according to EN 10210-1: S235JRH, S275J0H, S275J2H, S275NLH, S355J0H, S355J2H, S355NH, S355NLH, S420NH, S420NLH, S460NH, S460NLH
Steel designation for hollow sections of non-alloy steel
Steel designation for hollow sections of fine grain steel
according to DIN 17124: EStE255, EStE285, EStE355, EStE420, EStE460, RSt37-2, St37-3, St44-2, St44-3, St52-3, StE255, StE285, StE355, StE420, StE460, TStE255, TStE285, TStE355, TStE420, TStE460
Outside diameter: from 10,2 mm to 139,7 mm
Wall thickness: from 0,5 mm to 12,5 mm
Dimensions and weight of seamless steel tubes according to EN 10220
Tubes from outside diameter D ≥ 21,3 mm and wall thickness T ≥ 2,3 mm are supplied hot finished. Other dimensions and precision tubes are produced by cold drawing.
Packing
Structural hollow sections are supplied in packages with a circular or hexagonal diameter with a weight of 300 to 3500 kilograms. The tubes are bound with a steel band. It is also possible to wrap tubes in plastic sheets, burlap or in wooden crates.
Surface protection
It is possible to galvanize all construction steel grades, but the quality, appearance and thickness of layer depend on the chemical composition of steel (Si + P). To avoid the corrosion process it is recommended that the content of Si + P was in the range of 0.13% – 0.28%.
