  1. 1.Weight per foot (from AISC)per AISC Shapes Database v16.0

    W12X22 is a listed shape; its nominal weight is a published property.

    = 22 lb/ft
  2. 2.Length in feet
    length (in) ÷ 12
    240 ÷ 12
    = 20 ft
  3. 3.Weight per piece
    weight per foot × length
    22 × 20
    = 440 lb
  4. 4.Total weight
    weight per piece × quantity
    440 × 1
    = 440 lb
  5. 5.Convert to tons
    total lb ÷ 2000
    440 ÷ 2000
    = 0.22 tons

Before you rely on this
  • Listed weight is the AISC theoretical (nominal) weight per foot. Actual mill weight varies within ASTM rolling tolerance, roughly ±2.5%.
  • This is bare member steel only. Add plates, stiffeners, connections, bolts, and coatings for a full erected-steel takeoff.

W12x22 — questions

How much does a W12x22 weigh per foot?
A W12x22 weighs 22 lb/ft. Over a 20-foot length that is 440 lb (0.22 tons); a 30-foot length is 660 lb.
What are the dimensions of a W12x22?
W12x22 has an actual depth of 12.31 in and a flange width of 4.03 in, a flange thickness of 0.425 in, and a web thickness of 0.26 in. Cross-sectional area is 6.48 in².
What is the moment of inertia and section modulus of a W12x22?
About its strong axis, W12x22 has a moment of inertia Ix of 156 in⁴ and a section modulus Sx of 25.4 in³, with a plastic section modulus Zx of 29.3 in³. Use these with your engineer's design values — they are geometric properties, not an allowable load.
What does W12x22 mean?
The W means wide-flange. The first number is the nominal depth in inches and the second is the weight in pounds per foot — so W12x22 is a nominally 12-inch-deep wide-flange beam weighing 22 lb/ft (actual depth 12.31 in).
