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

    HSS3X3X1/4 is a listed shape; its nominal weight is a published property.

    = 8.81 lb/ft
  2. 2.Length in feet
    length (in) ÷ 12
    240 ÷ 12
    = 20 ft
  3. 3.Weight per piece
    weight per foot × length
    8.81 × 20
    = 176.2 lb
  4. 4.Total weight
    weight per piece × quantity
    176.2 × 1
    = 176.2 lb
  5. 5.Convert to tons
    total lb ÷ 2000
    176.2 ÷ 2000
    = 0.088 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.

HSS3x3x1/4 — questions

How much does a HSS3x3x1/4 weigh per foot?
A HSS3x3x1/4 weighs 8.81 lb/ft. Over a 20-foot length that is 176 lb (0.088 tons); a 30-foot length is 264 lb.
What are the dimensions of a HSS3x3x1/4?
HSS3x3x1/4 is 3 in deep by 3 in wide with a 0.233 in design wall thickness (nominal 0.25 in), and a cross-sectional area of 2.44 in².
What is the moment of inertia and section modulus of a HSS3x3x1/4?
About its strong axis, HSS3x3x1/4 has a moment of inertia Ix of 3 in⁴ and a section modulus Sx of 2.01 in³, with a plastic section modulus Zx of 2.52 in³. Use these with your engineer's design values — they are geometric properties, not an allowable load.
