Weight per Beam vs Beam Weight
公式
## Steel Beam Weight **Weight = Weight per Foot x Length** Steel beams are designated by their weight per linear foot (e.g., W8x31 weighs 31 lbs/ft). Multiply by the cut length to get the total weight for ordering, shipping, and crane planning.
计算示例
One W8x31 beam, 20 feet long.
- 01Weight = 31 x 20 = 620 lbs
- 02Total = 620 lbs = 0.31 tons
常见问题
What does W8x31 mean?
W means wide flange, 8 is the approximate depth in inches, and 31 is the weight in pounds per foot. The actual depth may vary slightly from the nominal designation.
How much does structural steel cost?
Fabricated structural steel typically costs $0.75 to $2.00 per pound installed, depending on complexity, coatings, and market conditions. Raw material alone is roughly $0.40-0.80 per pound.
