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

    W14X120 is a listed shape; its nominal weight is a published property.

    = 120 lb/ft
  2. 2.Length in feet
    length (in) ÷ 12
    240 ÷ 12
    = 20 ft
  3. 3.Weight per piece
    weight per foot × length
    120 × 20
    = 2400 lb
  4. 4.Total weight
    weight per piece × quantity
    2400 × 1
    = 2400 lb
  5. 5.Convert to tons
    total lb ÷ 2000
    2400 ÷ 2000
    = 1.2 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.

W14x120 — questions

How much does a W14x120 weigh per foot?
A W14x120 weighs 120 lb/ft. Over a 20-foot length that is 2,400 lb (1.2 tons); a 30-foot length is 3,600 lb.
What are the dimensions of a W14x120?
W14x120 has an actual depth of 14.48 in and a flange width of 14.67 in, a flange thickness of 0.94 in, and a web thickness of 0.59 in. Cross-sectional area is 35.3 in².
What is the moment of inertia and section modulus of a W14x120?
About its strong axis, W14x120 has a moment of inertia Ix of 1,380 in⁴ and a section modulus Sx of 190 in³, with a plastic section modulus Zx of 212 in³. Use these with your engineer's design values — they are geometric properties, not an allowable load.
What does W14x120 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 W14x120 is a nominally 14-inch-deep wide-flange beam weighing 120 lb/ft (actual depth 14.48 in).
