Frequently Asked Questions - Steel Weight Calculator
Standard structural steel (A36) has a density of 0.284 lb/in³ or 7850 kg/m³. This density is used for most carbon steel calculations. Stainless steel is slightly denser at about 0.290 lb/in³, while aluminum is much lighter at 0.098 lb/in³. Our calculator uses the standard steel density by default but allows custom values for different materials.
Our calculations are highly accurate for theoretical weights based on nominal dimensions and standard density. Actual weights may vary by ±2-3% due to manufacturing tolerances, steel grade variations, and surface treatments. For critical applications, always verify with actual weighing or manufacturer specifications.
The calculator supports plates, round bars, square bars, pipes/tubes, I-beams (W-shapes), channels, and angle iron. For I-beams, we include common standard sizes with their weight per foot. For other structural shapes like HSS tubes or custom profiles, use the closest equivalent shape or contact us for additional options.
For pipes and hollow sections, enter the outer diameter and wall thickness. The calculator automatically computes the inner diameter and subtracts the hollow volume. For rectangular tubes, use the plate calculator for each wall section, or contact us about adding HSS (Hollow Structural Section) calculations.
Yes! Simply change the density value to match your material. Common densities: Aluminum (0.098 lb/in³), Stainless Steel (0.290 lb/in³), Brass (0.307 lb/in³), Copper (0.324 lb/in³). The calculator works for any metallic material when you input the correct density.
