W10x22 — Dimensions, Weight & Section Properties
American wide-flange (W) beam per ASTM A6 / AISC Steel Construction Manual
W10x22 is an American wide-flange beam 10.2 inches (259.1 mm) deep with a 5.75 in (146 mm) flange, weighing 22 pounds per foot (32.7 kg/m) — that is what the "22" 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 W10x22 spanning 16 ft with a 10 kip point load at midspan deflects 0.43 in (E = 29,000 ksi, Ix = 118 in⁴). The L/360 serviceability limit for this span is 0.53 in — the shape passes this quick check.

Frequently asked questions
How much does a W10x22 beam weigh?
W10x22 weighs 22 pounds per foot (32.7 kg/m). The number after the "x" in the designation is always the weight in lb/ft. A 20 ft bar weighs 440 lb and a 40 ft bar 880 lb.
What are the dimensions of a W10x22?
W10x22 is 10.2 in (259.1 mm) deep with a 5.75 in (146 mm) wide flange. The web is 0.24 in thick and the flanges are 0.36 in thick. Note the actual depth differs from the nominal W10 label — always design with the actual value.
What are the dimensions of a W10x22 in mm?
W10x22 is 259.1 mm deep with a 146 mm wide flange; the web is 6.1 mm and the flange 9.1 mm thick. In metric section properties: Ix = 4,912 cm⁴, Sx = 380 cm³.
How much does a W10x22 weigh in kg?
32.7 kg per meter. A 6 m bar weighs 196 kg and a 12 m bar 393 kg — handy when ordering US shapes from metric suppliers.
What is the moment of inertia of a W10x22?
About the strong axis, Ix = 118 in⁴ (4,912 cm⁴) with section modulus Sx = 23.2 in³. About the weak axis, Iy = 11.4 in⁴ and Sy = 3.97 in³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
W10x22 or W10x26 — what does one size up change?
W10x26 is about 18% heavier (26 vs 22 lb/ft) but about 22% stiffer (Ix 144 vs 118 in⁴). Going one step up within the same depth group is usually the cheapest way to cut deflection.
