Rebar & Steel calculators

Reinforcement is bought by weight and detailed by length, so most rebar problems are a conversion between the two. These tools cover the conversion and the bar counting; lap lengths and bending details come from your bar bending schedule.

• Rebar Weight Calculator Calculate the weight of reinforcement bars from diameter, length and quantity.
• Rebar Spacing Calculator Work out how many bars fit across a span at a given maximum spacing, and the total bar length for a one-way or two-way mat.
