W36x210 — Dimensions, Weight & Section Properties
American wide-flange (W) beam per ASTM A6 / AISC Steel Construction Manual
W36x210 is an American wide-flange beam 36.7 inches (932.2 mm) deep with a 12.2 in (309.9 mm) flange, weighing 210 pounds per foot (312.5 kg/m) — that is what the "210" 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 W36x210 spanning 59 ft with a 10 kip point load at midspan deflects 0.19 in (E = 29,000 ksi, Ix = 13,200 in⁴). The L/360 serviceability limit for this span is 1.97 in — the shape passes this quick check.

Frequently asked questions
How much does a W36x210 beam weigh?
W36x210 weighs 210 pounds per foot (312.5 kg/m). The number after the "x" in the designation is always the weight in lb/ft. A 20 ft bar weighs 4,200 lb and a 40 ft bar 8,400 lb.
What are the dimensions of a W36x210?
W36x210 is 36.7 in (932.2 mm) deep with a 12.2 in (309.9 mm) wide flange. The web is 0.83 in thick and the flanges are 1.36 in thick. Note the actual depth differs from the nominal W36 label — always design with the actual value.
What are the dimensions of a W36x210 in mm?
W36x210 is 932.2 mm deep with a 309.9 mm wide flange; the web is 21.1 mm and the flange 34.5 mm thick. In metric section properties: Ix = 549,424 cm⁴, Sx = 11,782 cm³.
How much does a W36x210 weigh in kg?
312.5 kg per meter. A 6 m bar weighs 1,875 kg and a 12 m bar 3,750 kg — handy when ordering US shapes from metric suppliers.
What is the moment of inertia of a W36x210?
About the strong axis, Ix = 13,200 in⁴ (549,424 cm⁴) with section modulus Sx = 719 in³. About the weak axis, Iy = 411 in⁴ and Sy = 67.5 in³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
W36x210 or W36x232 — what does one size up change?
W36x232 is about 10% heavier (232 vs 210 lb/ft) but about 14% stiffer (Ix 15,000 vs 13,200 in⁴). Going one step up within the same depth group is usually the cheapest way to cut deflection.
