Calculate steel weight for plates, flat bars, square bars, round bars, pipes, round tubes, rectangular tubes, angles, channels, and custom steel shapes. Estimate weight per piece, total steel weight, weight per foot, weight per square foot, material cost, and shipping weight for structural planning.
Shape area:
The calculator estimates cross-sectional area from the selected steel shape and dimensions.
Volume:
The calculator multiplies cross-sectional area by length to estimate volume per piece.
Weight:
The calculator multiplies volume by density, then applies quantity, waste, coating add-on, and shipping factor.
Cost:
The calculator estimates material cost using cost per pound and also compares a cost-per-foot estimate.
A steel weight calculator helps estimate material weight before ordering, lifting, shipping, pricing, or planning fabrication.
It can help compare weight per piece, total weight, weight per foot, cross-sectional area, volume, waste allowance, material cost, and shipping weight.
Your result shows estimated cross-sectional area, volume per piece, weight per foot, weight per piece, total weight, waste allowance, coating add-on, shipping weight, cost by weight, and cost by length. These are planning estimates only.
Calculate the steel volume, then multiply by density. For carbon steel, a common estimate is 490 pounds per cubic foot.
Steel plate weight depends on length, width, thickness, and density. A common shortcut is volume in cubic feet multiplied by 490 lb/ft³ for carbon steel.
Both are calculated by subtracting the hollow inside area from the outside area, then multiplying by length and density. Exact pipe weights may also depend on nominal pipe size and schedule.
This calculator is useful for estimates. For final purchasing, shipping, or engineering calculations, use supplier tables, actual section properties, mill tolerances, and project specifications.
