Rebar Material Calculator - Inch Calculator

When installing a concrete slab or structure it is a good idea to add rebar, or reinforcing bar, to reinforce it and prevent it from cracking down the road. Using rebar as reinforcement adds considerable strength to concrete and reduces the overall slab thickness needed. Calculating the amount of bar needed can be done in a few simple steps.
