W27x94 — Dimensions, Weight & Section Properties
American wide-flange (W) beam per ASTM A6 / AISC Steel Construction Manual
W27x94 is an American wide-flange beam 26.9 inches (683.3 mm) deep with a 10 in (254 mm) flange, weighing 94 pounds per foot (139.9 kg/m) — that is what the "94" 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 W27x94 spanning 43 ft with a 10 kip point load at midspan deflects 0.3 in (E = 29,000 ksi, Ix = 3,270 in⁴). The L/360 serviceability limit for this span is 1.43 in — the shape passes this quick check.

Frequently asked questions
How much does a W27x94 beam weigh?
W27x94 weighs 94 pounds per foot (139.9 kg/m). The number after the "x" in the designation is always the weight in lb/ft. A 20 ft bar weighs 1,880 lb and a 40 ft bar 3,760 lb.
What are the dimensions of a W27x94?
W27x94 is 26.9 in (683.3 mm) deep with a 10 in (254 mm) wide flange. The web is 0.49 in thick and the flanges are 0.75 in thick. Note the actual depth differs from the nominal W27 label — always design with the actual value.
What are the dimensions of a W27x94 in mm?
W27x94 is 683.3 mm deep with a 254 mm wide flange; the web is 12.4 mm and the flange 18.9 mm thick. In metric section properties: Ix = 136,107 cm⁴, Sx = 3,982 cm³.
How much does a W27x94 weigh in kg?
139.9 kg per meter. A 6 m bar weighs 839 kg and a 12 m bar 1,679 kg — handy when ordering US shapes from metric suppliers.
What is the moment of inertia of a W27x94?
About the strong axis, Ix = 3,270 in⁴ (136,107 cm⁴) with section modulus Sx = 243 in³. About the weak axis, Iy = 124 in⁴ and Sy = 24.8 in³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
W27x94 or W27x102 — what does one size up change?
W27x102 is about 9% heavier (102 vs 94 lb/ft) but about 11% stiffer (Ix 3,620 vs 3,270 in⁴). Going one step up within the same depth group is usually the cheapest way to cut deflection.
