W16x67 — Dimensions, Weight & Section Properties
American wide-flange (W) beam per ASTM A6 / AISC Steel Construction Manual
W16x67 is an American wide-flange beam 16.3 inches (414 mm) deep with a 10.2 in (259.1 mm) flange, weighing 67 pounds per foot (99.7 kg/m) — that is what the "67" 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 W16x67 spanning 26 ft with a 10 kip point load at midspan deflects 0.23 in (E = 29,000 ksi, Ix = 954 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 W16x67 beam weigh?
W16x67 weighs 67 pounds per foot (99.7 kg/m). The number after the "x" in the designation is always the weight in lb/ft. A 20 ft bar weighs 1,340 lb and a 40 ft bar 2,680 lb.
What are the dimensions of a W16x67?
W16x67 is 16.3 in (414 mm) deep with a 10.2 in (259.1 mm) wide flange. The web is 0.4 in thick and the flanges are 0.67 in thick. Note the actual depth differs from the nominal W16 label — always design with the actual value.
What are the dimensions of a W16x67 in mm?
W16x67 is 414 mm deep with a 259.1 mm wide flange; the web is 10 mm and the flange 16.9 mm thick. In metric section properties: Ix = 39,708 cm⁴, Sx = 1,917 cm³.
How much does a W16x67 weigh in kg?
99.7 kg per meter. A 6 m bar weighs 598 kg and a 12 m bar 1,197 kg — handy when ordering US shapes from metric suppliers.
What is the moment of inertia of a W16x67?
About the strong axis, Ix = 954 in⁴ (39,708 cm⁴) with section modulus Sx = 117 in³. About the weak axis, Iy = 119 in⁴ and Sy = 23.2 in³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
W16x67 or W16x77 — what does one size up change?
W16x77 is about 15% heavier (77 vs 67 lb/ft) but about 16% stiffer (Ix 1,110 vs 954 in⁴). Going one step up within the same depth group is usually the cheapest way to cut deflection.
