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

    C10X20 is a listed shape; its nominal weight is a published property.

    = 20 lb/ft
  2. 2.Length in feet
    length (in) ÷ 12
    240 ÷ 12
    = 20 ft
  3. 3.Weight per piece
    weight per foot × length
    20 × 20
    = 400 lb
  4. 4.Total weight
    weight per piece × quantity
    400 × 1
    = 400 lb
  5. 5.Convert to tons
    total lb ÷ 2000
    400 ÷ 2000
    = 0.2 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.

C10x20 — questions

How much does a C10x20 weigh per foot?
A C10x20 weighs 20 lb/ft. Over a 20-foot length that is 400 lb (0.2 tons); a 30-foot length is 600 lb.
What are the dimensions of a C10x20?
C10x20 has an actual depth of 10 in and a flange width of 2.739 in, a flange thickness of 0.436 in, and a web thickness of 0.379 in. Cross-sectional area is 5.87 in².
What is the moment of inertia and section modulus of a C10x20?
About its strong axis, C10x20 has a moment of inertia Ix of 78.9 in⁴ and a section modulus Sx of 15.8 in³, with a plastic section modulus Zx of 19.3 in³. Use these with your engineer's design values — they are geometric properties, not an allowable load.
