W14x605 — Dimensions, Weight & Section Properties
American wide-flange (W) beam per ASTM A6 / AISC Steel Construction Manual
W14x605 is an American wide-flange beam 20.9 inches (530.9 mm) deep with a 17.4 in (442 mm) flange, weighing 605 pounds per foot (900.4 kg/m) — that is what the "605" 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 W14x605 spanning 33 ft with a 10 kip point load at midspan deflects 0.04 in (E = 29,000 ksi, Ix = 10,800 in⁴). The L/360 serviceability limit for this span is 1.1 in — the shape passes this quick check.

Frequently asked questions
How much does a W14x605 beam weigh?
W14x605 weighs 605 pounds per foot (900.4 kg/m). The number after the "x" in the designation is always the weight in lb/ft. A 20 ft bar weighs 12,100 lb and a 40 ft bar 24,200 lb.
What are the dimensions of a W14x605?
W14x605 is 20.9 in (530.9 mm) deep with a 17.4 in (442 mm) wide flange. The web is 2.6 in thick and the flanges are 4.16 in thick. Note the actual depth differs from the nominal W14 label — always design with the actual value.
What are the dimensions of a W14x605 in mm?
W14x605 is 530.9 mm deep with a 442 mm wide flange; the web is 66 mm and the flange 105.7 mm thick. In metric section properties: Ix = 449,528 cm⁴, Sx = 17,042 cm³.
How much does a W14x605 weigh in kg?
900.4 kg per meter. A 6 m bar weighs 5,402 kg and a 12 m bar 10,804 kg — handy when ordering US shapes from metric suppliers.
What is the moment of inertia of a W14x605?
About the strong axis, Ix = 10,800 in⁴ (449,528 cm⁴) with section modulus Sx = 1,040 in³. About the weak axis, Iy = 3,680 in⁴ and Sy = 423 in³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
W14x605 or W14x665 — what does one size up change?
W14x665 is about 10% heavier (665 vs 605 lb/ft) but about 15% stiffer (Ix 12,400 vs 10,800 in⁴). Going one step up within the same depth group is usually the cheapest way to cut deflection.
