These free calculators help with everyday metal and fabrication work. You can estimate the weight of bars, beams, pipes, sheets and rebar, check sheet gauge thickness, work out bend allowance, and get a rough idea of cutting, welding and powder coating needs.
Pick a calculator below, enter your sizes and material, and the result shows on the same page. Results are estimates based on standard formulas and typical values, so please check them against your supplier’s data or your drawing before ordering or cutting material.
