Reinforcing bar grid
Use a prescribed grid layout to estimate straight bars. This is useful when a drawing already specifies diameter, maximum spacing and cover.

Choose by the shape and the job
Reinforcing mesh sheets & rolls
For a rectangular area covered with manufactured mesh. Enter the actual product dimensions rather than estimating individual wires.
Straight bars & cutting list
For an existing drawing or a measured list of straight pieces, including mixed lengths. No slab geometry is needed.
Three different starting points
Grid starts with a rectangle, clear cover and bar centres in two directions. Mesh starts with the dimensions of a manufactured sheet or roll. Straight Bars starts with pieces already specified. These tools estimate quantities; they do not design structural reinforcement.
Installed steel and stock to buy
A grid or piece list describes the bars in the job. Purchase & Cut adds stock lengths, any specified laps and cutting losses. Mesh instead counts complete sheets or packs strip lengths into rolls, keeping overlap and material outside the project visible.
