Formula

Volume per bar = width × thickness × length. Weight = volume × density × quantity.

Steel density

The preset uses 7,850 kg/m³. Replace it with the actual alloy density when a closer estimate is required.

Scope

This is a solid rectangular flat-bar estimate. It does not account for rounded corners, rolling tolerances, coatings or structural capacity.
