Rebar Calc is the easiest way to calculate rebar, mesh, concrete, and bags of grout or fast setting concrete!

Rebar Calc is a multi function calculator allowing you to calculate the tons and linear feet of rebar, sheets of sheet mesh, and rolls of roll mesh required for a given area of concrete. Rebar Calc also allows you to configure the amount of lap necessary for your job, the size of the rebar, sheet mesh, or roll mesh.

In addition, Rebar Calc provides a quick easy concrete volume estimator in cubic yards, a quick calculator to calculate how many bags of grout, fast setting concrete, etc. are needed for a slab or concrete cores, and a quick and easy connection to get a quote on rebar, mesh, or other concrete supplies.

These calculations are for estimating purposes only. All final figures should be verified by a professional before quoting, purchasing, or installing materials.

Amazing App

I have to say, I thought I was going to be disappointed by another wanna be App when I downloaded it. As soon as I opened the app and started to use it I was shocked. The ease of operating and simple functions make this a must have App for any Contractor who does Concrete and Rebar. Great job guys. Thumbs up for sure.
