Work out the weight of plate, bar, tube, hollow section or sheet from its dimensions and material. Pick the shape and material, enter the dimensions and quantity, and get weight per piece, per metre and total, with the volume shown alongside.
What it gives you
- Plate, sheet, round bar, flat bar, square bar, hexagon, round tube, square and rectangular hollow sections
- Carbon steel, stainless, aluminium, copper, brass, titanium and more with typical densities
- Weight per metre and per piece
- Total for a quantity
- Volume for costing and shipping
Method and standards
Weight is volume times density. Densities are typical handbook values: 7850 kg/m³ for carbon steel, 8000 for austenitic stainless, 2700 for aluminium, 8940 for copper. For structural sections the tabulated mass per metre from the steel section lookup is more accurate than a calculated value because it accounts for root radii and rolling tolerances.
How to use it
- Choose the shape and material.
- Enter the dimensions and quantity.
- Read weight per piece, per metre and total.
Questions engineers ask
- Does it include mill tolerance?
- No. Real plate and sheet can weigh several percent more or less than nominal; use the tolerance from the material standard for procurement quantities.
- Can I add a custom density?
- Yes. Choose custom and enter the density.
- What about universal beams and channels?
- Use the steel section lookup, which gives the standard mass per metre for UB, UC, PFC, angles and hollow sections.
