Use case

Get bar stock weight before the quote goes out.

Profile-aware formulas keep your ordering weight and finish area aligned.

Trusted inputs

ASTM/ASM material property snapshots

Closed-form geometry for round/square/flat/hex bars

Range notes

Profile dimensions and length use the selected unit system.

Flat bar uses width x thickness rectangular section geometry.

Hex stock supports across-flats and circumscribed sizing.

Quantity and allowance are applied to order weight.

Supports catalog or custom material density with kg/m³ and lb/in³ input.

Inverse mode solves required bar length from a target weight.
