Steel Calculators
Last updated .
These three pages are the steel on the site. The weight calculator handles plate, flat bar, round and square bar, pipe, angle, channel, and an I-beam from the dimensions you type. It starts at 7,850 kg/m³, the same carbon-steel density as the rebar page. Other metals are planning figures you can change.
Rebar is the bar chart: metric 6 mm through 32 mm, and US #3 through #11, #14, and #18, in kilograms per meter and pounds per foot. Wire mesh counts sheets for a slab after the lap. A concrete pour, including premix bags, is the concrete hub.

US #3–#11 and metric 8–32 mm, and how a plan spacing becomes a count. Weights stay on the rebar calculator.
