Calculate the approximate weight of S355 steel plates, round bars, pipes and hollow sections quickly and accurately.
Calculate the approximate theoretical weight of S355 steel plates, bars, pipes, hollow sections, flats, angles, channels, beams, circular plates and annular rings.
The calculator uses a nominal steel density of 7.85 g/cm³ (7850 kg/m³). Weight is calculated from the actual geometric volume of the selected product.
S355 is a structural steel designation under the EN 10025 family. For hollow sections, the applicable product standards define the section geometry and manufacturing tolerances.
The result is a theoretical calculated weight, not a certified mill weight. For procurement, fabrication, structural design or other critical applications, verify the final weight against the manufacturer's certified dimensions, section tables and Mill Test Certificate.
