W14x233 — Dimensions, Weight & Section Properties
American wide-flange (W) beam per ASTM A6 / AISC Steel Construction Manual
W14x233 is an American wide-flange beam 16 inches (406.4 mm) deep with a 15.9 in (403.9 mm) flange, weighing 233 pounds per foot (346.8 kg/m) — that is what the "233" 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 W14x233 spanning 26 ft with a 10 kip point load at midspan deflects 0.07 in (E = 29,000 ksi, Ix = 3,010 in⁴). The L/360 serviceability limit for this span is 0.87 in — the shape passes this quick check.

Frequently asked questions
How much does a W14x233 beam weigh?
W14x233 weighs 233 pounds per foot (346.8 kg/m). The number after the "x" in the designation is always the weight in lb/ft. A 20 ft bar weighs 4,660 lb and a 40 ft bar 9,320 lb.
What are the dimensions of a W14x233?
W14x233 is 16 in (406.4 mm) deep with a 15.9 in (403.9 mm) wide flange. The web is 1.07 in thick and the flanges are 1.72 in thick. Note the actual depth differs from the nominal W14 label — always design with the actual value.
What are the dimensions of a W14x233 in mm?
W14x233 is 406.4 mm deep with a 403.9 mm wide flange; the web is 27.2 mm and the flange 43.7 mm thick. In metric section properties: Ix = 125,285 cm⁴, Sx = 6,145 cm³.
How much does a W14x233 weigh in kg?
346.8 kg per meter. A 6 m bar weighs 2,081 kg and a 12 m bar 4,161 kg — handy when ordering US shapes from metric suppliers.
What is the moment of inertia of a W14x233?
About the strong axis, Ix = 3,010 in⁴ (125,285 cm⁴) with section modulus Sx = 375 in³. About the weak axis, Iy = 1,150 in⁴ and Sy = 145 in³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
W14x233 or W14x257 — what does one size up change?
W14x257 is about 10% heavier (257 vs 233 lb/ft) but about 13% stiffer (Ix 3,400 vs 3,010 in⁴). Going one step up within the same depth group is usually the cheapest way to cut deflection.
