Calculate structural steel linear weight, total tonnage, and material pricing across Wide Flange I-beams, C-channels, L-angles, square/rectangular HSS tubing, round pipe, and flat bar stock.
Standard American structural steel members encode their nominal depth and weight per linear foot directly into their name: In W8x24, "W" indicates Wide Flange, "8" denotes roughly 8 inches nominal depth, and "24" means it weighs exactly 24.0 pounds per linear foot.
For Hollow Structural Sections (HSS), calculate cross-sectional metal area:
Area = 2t(H + W - 2t).
Multiply by steel density (0.2833 lbs/in³) and 12 inches to obtain exact weight per foot.
Angle iron weight is calculated by summing the two legs and subtracting the overlapping corner thickness:
Weight (lbs/ft) = (Leg 1 + Leg 2 - Thickness) x Thickness x 3.40.
OSHA requires all steel lifting rigging slings, shackles, and spreader beams to be rated with a minimum 5:1 safety factor based on the gross member weight plus connection hardware.
| Designation | Profile Family | Weight (lbs/ft) | Weight (kg/m) | Common Structural Use |
|---|---|---|---|---|
| W8 x 24 | Wide Flange I-Beam | 24.0 lbs/ft | 35.7 kg/m | Basement center girders, floor beams |
| W10 x 30 | Wide Flange I-Beam | 30.0 lbs/ft | 44.6 kg/m | Commercial headers, multi-story joist carriers |
| C6 x 8.2 | American Standard Channel | 8.2 lbs/ft | 12.2 kg/m | Stair stringers, trailer frames, equipment skids |
| L4 x 3 x 1/4 | Unequal Leg Angle | 5.8 lbs/ft | 8.6 kg/m | Brick shelf angles, masonry lintels |
| HSS 4 x 4 x 1/4 | Square Structural Tube | 12.2 lbs/ft | 18.2 kg/m | Building columns, carports, equipment legs |
Rigging heavy structural steel shapes without calculating exact dead weight risks snapping synthetic slings, exceeding mobile crane boom load charts, or triggering severe jobsite safety hazards.
Steel has an immense density of ~490 lbs/cu ft. Loading flatbed trailers without calculating batch weights frequently exceeds federal 80,000-lb gross vehicle weight regulations, resulting in steep highway fines and mandatory offloading.
Steel service centers and fabricators buy and sell steel by weight (price per pound or cwt). Estimating linear footage without converting to exact pounds leads to inaccurate client bids and unexpected profit margin erosion.
Grade 304 and 316 stainless steels are denser than standard mild carbon steel (0.285 to 0.290 lb/in³ vs. 0.2836 lb/in³). Using generic steel formulas causes cumulative weight errors on large architectural installations.
Choose from 8 profiles: Plate, Round Bar, Square Bar, Hex Bar, Round Pipe, Square Tube, Angle, or I-Beam.
Select Carbon Steel (A36), Stainless Steel (304/316), Alloy Steel (4140), or Tool Steel (D2).
Enter cross-section dimensions (thickness, width, diameter, or pipe wall gauge) in inches or millimeters.
Input total length per piece and total quantity in the fabrication order.
Review total weight in lbs and tonnes, weight per linear foot, and total order cost based on price per pound.
Solves Flat Plates, Solid Rounds, Squares, Hex Bars, Round Pipes, Structural Tubing, Angles, and I-Beams.
