Practical guides on steel weight formulas, kg/m tables, IPE beams, and how to use the Iron Metal catalog and calculators.
Steel weight equals volume × density. Use 7850 kg/m³ (7.85 g/cm³) for carbon steel, then multiply by length and quantity in the calculator.
IPE weight per meter is listed on each size page in the catalog (theoretical kg/m). Multiply by length and quantity, or use the calculator for pricing and totals.
HP and H beam weight per meter is listed as theoretical kg/m on each catalog size page. Multiply by length and quantity, or use the I/H beam calculator for totals.
Equal angle weight per meter depends on leg size and thickness. Open the angle sector, read kg/m on the size page, then multiply by length or use the equal-angle calculator.
Plate weight = length × width × thickness × density. For carbon steel use 7850 kg/m³ (7.85 g/cm³). Enter dimensions in the plate calculator for kg per piece and totals.
Rebar weight per meter ≈ (π × d² / 4) × ρ for solid round bar, or read kg/m tables for standard diameters. Use 7850 kg/m³ for carbon steel rebar.
Pipe weight per meter = cross-section area × density. For hollow tube: area = π/4 × (OD² − ID²). Carbon steel density 7850 kg/m³. Use the round tube calculator for quick totals.
U channel weight per meter is published as theoretical kg/m for each standard size. Open the U/C sector, read kg/m, multiply by length, or use the U channel calculator.
Carbon steel is typically 7.85 g/cm³ (7850 kg/m³). Stainless grades range ~7.9–8.0 g/cm³. Always match density to the material in your mill certificate or calculator setting.
Catalog and handbook kg/m values are theoretical. Actual weight varies with mill tolerance, fillet radii, and length measurement. For procurement, agree whether quotes use theoretical or weighed mass.
The kg/m column is theoretical weight per one meter of length for that size. Match the profile standard (IPE, UPN, L, etc.), open the size row, then multiply kg/m by your bar length and quantity.
List each line: section, size, kg/m, length, quantity. Line weight = kg/m × L × qty. Sum lines for total tonnes; add waste factor (often 3–8%) per project.
