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

    W10X30 is a listed shape; its nominal weight is a published property.

    = 30 lb/ft
  2. 2.Length in feet
    length (in) ÷ 12
    240 ÷ 12
    = 20 ft
  3. 3.Weight per piece
    weight per foot × length
    30 × 20
    = 600 lb
  4. 4.Total weight
    weight per piece × quantity
    600 × 1
    = 600 lb
  5. 5.Convert to tons
    total lb ÷ 2000
    600 ÷ 2000
    = 0.3 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.

W10x30 — questions

How much does a W10x30 weigh per foot?
A W10x30 weighs 30 lb/ft. Over a 20-foot length that is 600 lb (0.3 tons); a 30-foot length is 900 lb.
What are the dimensions of a W10x30?
W10x30 has an actual depth of 10.47 in and a flange width of 5.81 in, a flange thickness of 0.51 in, and a web thickness of 0.3 in. Cross-sectional area is 8.84 in².
What is the moment of inertia and section modulus of a W10x30?
About its strong axis, W10x30 has a moment of inertia Ix of 170 in⁴ and a section modulus Sx of 32.4 in³, with a plastic section modulus Zx of 36.6 in³. Use these with your engineer's design values — they are geometric properties, not an allowable load.
What does W10x30 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 W10x30 is a nominally 10-inch-deep wide-flange beam weighing 30 lb/ft (actual depth 10.47 in).
