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

    HSS8X8X1/4 is a listed shape; its nominal weight is a published property.

    = 25.82 lb/ft
  2. 2.Length in feet
    length (in) ÷ 12
    240 ÷ 12
    = 20 ft
  3. 3.Weight per piece
    weight per foot × length
    25.82 × 20
    = 516.4 lb
  4. 4.Total weight
    weight per piece × quantity
    516.4 × 1
    = 516.4 lb
  5. 5.Convert to tons
    total lb ÷ 2000
    516.4 ÷ 2000
    = 0.258 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.
