W36x194 — Dimensions, Weight & Section Properties
American wide-flange (W) beam per ASTM A6 / AISC Steel Construction Manual
W36x194 is an American wide-flange beam 36.5 inches (927.1 mm) deep with a 12.1 in (307.3 mm) flange, weighing 194 pounds per foot (288.7 kg/m) — that is what the "194" 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 W36x194 spanning 58 ft with a 10 kip point load at midspan deflects 0.2 in (E = 29,000 ksi, Ix = 12,100 in⁴). The L/360 serviceability limit for this span is 1.93 in — the shape passes this quick check.

Frequently asked questions
How much does a W36x194 beam weigh?
W36x194 weighs 194 pounds per foot (288.7 kg/m). The number after the "x" in the designation is always the weight in lb/ft. A 20 ft bar weighs 3,880 lb and a 40 ft bar 7,760 lb.
What are the dimensions of a W36x194?
W36x194 is 36.5 in (927.1 mm) deep with a 12.1 in (307.3 mm) wide flange. The web is 0.77 in thick and the flanges are 1.26 in thick. Note the actual depth differs from the nominal W36 label — always design with the actual value.
What are the dimensions of a W36x194 in mm?
W36x194 is 927.1 mm deep with a 307.3 mm wide flange; the web is 19.4 mm and the flange 32 mm thick. In metric section properties: Ix = 503,638 cm⁴, Sx = 10,881 cm³.
How much does a W36x194 weigh in kg?
288.7 kg per meter. A 6 m bar weighs 1,732 kg and a 12 m bar 3,465 kg — handy when ordering US shapes from metric suppliers.
What is the moment of inertia of a W36x194?
About the strong axis, Ix = 12,100 in⁴ (503,638 cm⁴) with section modulus Sx = 664 in³. About the weak axis, Iy = 375 in⁴ and Sy = 61.9 in³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
W36x194 or W36x210 — what does one size up change?
W36x210 is about 8% heavier (210 vs 194 lb/ft) but about 9% stiffer (Ix 13,200 vs 12,100 in⁴). Going one step up within the same depth group is usually the cheapest way to cut deflection.
