What this calculator does

It estimates weight from cross-sectional area, length and a typical material density. It is useful for quoting, handling, trailer/load planning and comparing stock options.

Why actual weight can differ

Mill tolerances, corner radii, tubing manufacturing tolerances and alloy chemistry can move actual weight away from the estimate. For purchasing or engineered loads, use the mill/supplier weight when available.
