What unit of measurement is used to estimate a steel structure?

• A. Ton
• B. Pound
• C. Kilogram
• D. Cubic yard

Answer: (A)

Estimating a steel structure is done by weight because pricing and procurement are driven by how much steel is used. In US practice, the total weight is expressed in tons, with one ton equal to 2,000 pounds, and shipments and fabrication quotes are commonly given per ton. While you might see pounds or kilograms used for the weight of individual members, the overall estimate for a project is typically stated in tons to keep the numbers manageable. Kilograms and cubic yards aren’t used for steel structure estimation—the cubic yard is for concrete, and kilograms are not convenient for large-scale steel quantities. So the standard unit for estimating a steel structure is the ton.
