W36x182 — Dimensions, Weight & Section Properties
American wide-flange (W) beam per ASTM A6 / AISC Steel Construction Manual
W36x182 is an American wide-flange beam 36.3 inches (922 mm) deep with a 12.1 in (307.3 mm) flange, weighing 182 pounds per foot (270.9 kg/m) — that is what the "182" 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 W36x182 spanning 58 ft with a 10 kip point load at midspan deflects 0.21 in (E = 29,000 ksi, Ix = 11,300 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 W36x182 beam weigh?
W36x182 weighs 182 pounds per foot (270.9 kg/m). The number after the "x" in the designation is always the weight in lb/ft. A 20 ft bar weighs 3,640 lb and a 40 ft bar 7,280 lb.
What are the dimensions of a W36x182?
W36x182 is 36.3 in (922 mm) deep with a 12.1 in (307.3 mm) wide flange. The web is 0.73 in thick and the flanges are 1.18 in thick. Note the actual depth differs from the nominal W36 label — always design with the actual value.
What are the dimensions of a W36x182 in mm?
W36x182 is 922 mm deep with a 307.3 mm wide flange; the web is 18.4 mm and the flange 30 mm thick. In metric section properties: Ix = 470,340 cm⁴, Sx = 10,209 cm³.
How much does a W36x182 weigh in kg?
270.9 kg per meter. A 6 m bar weighs 1,625 kg and a 12 m bar 3,250 kg — handy when ordering US shapes from metric suppliers.
What is the moment of inertia of a W36x182?
About the strong axis, Ix = 11,300 in⁴ (470,340 cm⁴) with section modulus Sx = 623 in³. About the weak axis, Iy = 347 in⁴ and Sy = 57.6 in³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
W36x182 or W36x194 — what does one size up change?
W36x194 is about 7% heavier (194 vs 182 lb/ft) but about 7% stiffer (Ix 12,100 vs 11,300 in⁴). Going one step up within the same depth group is usually the cheapest way to cut deflection.
