W27x114 — Dimensions, Weight & Section Properties
American wide-flange (W) beam per ASTM A6 / AISC Steel Construction Manual
W27x114 is an American wide-flange beam 27.3 inches (693.4 mm) deep with a 10.1 in (256.5 mm) flange, weighing 114 pounds per foot (169.7 kg/m) — that is what the "114" 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 W27x114 spanning 44 ft with a 10 kip point load at midspan deflects 0.26 in (E = 29,000 ksi, Ix = 4,080 in⁴). The L/360 serviceability limit for this span is 1.47 in — the shape passes this quick check.

Frequently asked questions
How much does a W27x114 beam weigh?
W27x114 weighs 114 pounds per foot (169.7 kg/m). The number after the "x" in the designation is always the weight in lb/ft. A 20 ft bar weighs 2,280 lb and a 40 ft bar 4,560 lb.
What are the dimensions of a W27x114?
W27x114 is 27.3 in (693.4 mm) deep with a 10.1 in (256.5 mm) wide flange. The web is 0.57 in thick and the flanges are 0.93 in thick. Note the actual depth differs from the nominal W27 label — always design with the actual value.
What are the dimensions of a W27x114 in mm?
W27x114 is 693.4 mm deep with a 256.5 mm wide flange; the web is 14.5 mm and the flange 23.6 mm thick. In metric section properties: Ix = 169,822 cm⁴, Sx = 4,900 cm³.
How much does a W27x114 weigh in kg?
169.7 kg per meter. A 6 m bar weighs 1,018 kg and a 12 m bar 2,036 kg — handy when ordering US shapes from metric suppliers.
What is the moment of inertia of a W27x114?
About the strong axis, Ix = 4,080 in⁴ (169,822 cm⁴) with section modulus Sx = 299 in³. About the weak axis, Iy = 159 in⁴ and Sy = 31.5 in³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
W27x114 or W27x129 — what does one size up change?
W27x129 is about 13% heavier (129 vs 114 lb/ft) but about 17% stiffer (Ix 4,760 vs 4,080 in⁴). Going one step up within the same depth group is usually the cheapest way to cut deflection.
