W14x176 — Dimensions, Weight & Section Properties
American wide-flange (W) beam per ASTM A6 / AISC Steel Construction Manual
W14x176 is an American wide-flange beam 15.2 inches (386.1 mm) deep with a 15.7 in (398.8 mm) flange, weighing 176 pounds per foot (261.9 kg/m) — that is what the "176" 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 W14x176 spanning 24 ft with a 10 kip point load at midspan deflects 0.08 in (E = 29,000 ksi, Ix = 2,140 in⁴). The L/360 serviceability limit for this span is 0.8 in — the shape passes this quick check.

Frequently asked questions
How much does a W14x176 beam weigh?
W14x176 weighs 176 pounds per foot (261.9 kg/m). The number after the "x" in the designation is always the weight in lb/ft. A 20 ft bar weighs 3,520 lb and a 40 ft bar 7,040 lb.
What are the dimensions of a W14x176?
W14x176 is 15.2 in (386.1 mm) deep with a 15.7 in (398.8 mm) wide flange. The web is 0.83 in thick and the flanges are 1.31 in thick. Note the actual depth differs from the nominal W14 label — always design with the actual value.
What are the dimensions of a W14x176 in mm?
W14x176 is 386.1 mm deep with a 398.8 mm wide flange; the web is 21.1 mm and the flange 33.3 mm thick. In metric section properties: Ix = 89,073 cm⁴, Sx = 4,605 cm³.
How much does a W14x176 weigh in kg?
261.9 kg per meter. A 6 m bar weighs 1,572 kg and a 12 m bar 3,143 kg — handy when ordering US shapes from metric suppliers.
What is the moment of inertia of a W14x176?
About the strong axis, Ix = 2,140 in⁴ (89,073 cm⁴) with section modulus Sx = 281 in³. About the weak axis, Iy = 838 in⁴ and Sy = 107 in³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
W14x176 or W14x193 — what does one size up change?
W14x193 is about 10% heavier (193 vs 176 lb/ft) but about 12% stiffer (Ix 2,400 vs 2,140 in⁴). Going one step up within the same depth group is usually the cheapest way to cut deflection.
