Calculator ## Steel weight calculator Pick a section and size, enter the length and quantity, and get the total weight. Plate and flat bar are worked out from their dimensions at 7,850 kg/m³. * Section weight = mass per metre × length × quantity * Plate or flat bar weight = length × width × thickness × 7,850 kg/m³ × quantity A 305 × 165 × 40 UB is 40.3 kg/m, so four 6 m lengths weigh 40.3 × 6 × 4 = 967.2 kg. A 10 mm plate 1,000 × 500 mm weighs 1.0 × 0.5 × 0.01 × 7,850 = 39.25 kg. Weights are nominal and exclude coatings, plates and fittings. Weight calculatorkg The calculator needs JavaScript. Use the mass per metre from the table: weight = mass × length × quantity. Downloads ## PDF and CSV The PDF has every table with its diagram, on A4, ready to print. The CSV files suit spreadsheets, scripts and CAD tools.

We recalculated area, second moment of area and elastic modulus from the nominal dimensions for every size, and show a value only where it matches a published figure. Diagrams and layout are our own. ### Standards * **BS 4-1:2005** Structural steel sections. Specification for hot-rolled sections (UB, UC, PFC) * **BS EN 10365:2017** Hot rolled steel channels, I and H sections. Dimensions and masses * **BS EN 10056-1:2017** Structural steel equal and unequal leg angles. Dimensions * **BS EN 10210-2:2019** Hot finished steel structural hollow sections. Tolerances, dimensions and sectional properties * **BS EN 10219-2:2019** Cold formed welded steel structural hollow sections (not covered by these tables) ## Reference only Reference only. Values are nominal figures for the standard UK section ranges. Check them against current manufacturer data, and have a structural engineer confirm sizes before you use them in design.
