weight-formulameta_guide_steel_formula_lead
IPE単位重量（kg/m）— クイックガイド
beamsIPE 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/H形鋼 重量/メートル — クイックガイド
beamsHP 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 Steel Weight — kg/m Guide
anglesEqual 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.
Steel Plate & Sheet Weight Formula
platesPlate weight = length × width × thickness × density. For carbon steel use 7850 kg/m³ (7.85 g/cm³).
Rebar Weight per Meter — Calculation Guide
rebarRebar weight per meter uses diameter and density 7850 kg/m³, or read kg/m tables for standard diameters.
Pipe & Tube Weight per Meter
pipesPipe weight per meter = cross-section area × density. Carbon steel density 7850 kg/m³.
U Channel / C Channel Weight per Meter
channelsU channel weight per meter is published as theoretical kg/m for each standard size.
Steel Density Reference — g/cm³ & kg/m³
referenceCarbon steel is typically 7.85 g/cm³ (7850 kg/m³). Stainless grades range ~7.9–8.0 g/cm³.
Theoretical vs Actual Steel Weight
standardsCatalog kg/m values are theoretical. Actual weight varies with mill tolerance and length measurement.
How to Read kg/m Tables in a Steel Catalog
catalogThe kg/m column is theoretical weight per one meter. Multiply kg/m by bar length and quantity.
Estimate Total Steel Weight for Procurement
procurementLine weight = kg/m × L × qty. Sum across BOM lines and add project waste factor.
