Work out the weight of plate, bar and tube before you order material or book a lift. Pick a material and profile, punch in the dimensions, get the weight in kilograms. Nothing to sign up for.
Dimensions in millimetres, length in millimetres. Results are indicative for solid, uniform sections and don't account for holes, tapers or weld metal.
Figures are a guide only. Always confirm against mill certs and current material for critical or load-bearing work.
