W8x67 — Dimensions, Weight & Section Properties
American wide-flange (W) beam per ASTM A6 / AISC Steel Construction Manual
W8x67 is an American wide-flange beam 9 inches (228.6 mm) deep with a 8.28 in (210.3 mm) flange, weighing 67 pounds per foot (99.7 kg/m) — that is what the "67" in the designation means. All values below are the standard AISC published section properties used in US structural design, with metric equivalents alongside.
Typical uses: floor and roof framing, columns, headers, and general steel construction. For a quick stiffness check, see the deflection example below or open the beam calculator with your own span and load.

Deflection example
A simply supported W8x67 spanning 14 ft with a 10 kip point load at midspan deflects 0.13 in (E = 29,000 ksi, Ix = 272 in⁴). The L/360 serviceability limit for this span is 0.47 in — the shape passes this quick check.

Frequently asked questions
How much does a W8x67 beam weigh?
W8x67 weighs 67 pounds per foot (99.7 kg/m). The number after the "x" in the designation is always the weight in lb/ft. A 20 ft bar weighs 1,340 lb and a 40 ft bar 2,680 lb.
What are the dimensions of a W8x67?
W8x67 is 9 in (228.6 mm) deep with a 8.28 in (210.3 mm) wide flange. The web is 0.57 in thick and the flanges are 0.94 in thick. Note the actual depth differs from the nominal W8 label — always design with the actual value.
What are the dimensions of a W8x67 in mm?
W8x67 is 228.6 mm deep with a 210.3 mm wide flange; the web is 14.5 mm and the flange 23.7 mm thick. In metric section properties: Ix = 11,321 cm⁴, Sx = 990 cm³.
How much does a W8x67 weigh in kg?
99.7 kg per meter. A 6 m bar weighs 598 kg and a 12 m bar 1,197 kg — handy when ordering US shapes from metric suppliers.
What is the moment of inertia of a W8x67?
About the strong axis, Ix = 272 in⁴ (11,321 cm⁴) with section modulus Sx = 60.4 in³. About the weak axis, Iy = 88.6 in⁴ and Sy = 21.4 in³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
W8x67 or W8x58 — what does one size down change?
W8x58 is about 13% lighter (58 vs 67 lb/ft) but about 16% less stiff (Ix 228 vs 272 in⁴). Check deflection before downsizing — stiffness falls much faster than weight.
