Design the steel for a concrete slab: enter slab length, width and thickness, pick a rebar size and on-center spacing with cover and edge margins, and get the number of bars in each direction, total bar lengths, weight, lap-overlap guidance and an alternative welded-wire-mesh layout.
Checks that slab length, width, thickness, rebar size, on-center spacing, clear cover and edge margins are all positive, finite numbers with spacing greater than zero.
Awaiting input.
Verifies the clear cover plus bar diameter fits within the slab thickness (for the bottom reinforcement mat) and that your chosen edge margin is a sane minimum for bars running to the slab perimeter.
Awaiting input.
Judges the on-center spacing against common practice (150–450 mm / 6–18 in) and the slab thickness (sometimes bouts at 2–3× thickness). Warns when spacing is very tight or very wide.
Awaiting input.
Computes the total steel weight from the unit weight of the chosen bar size (or mesh grid), the number of bars and cutting lengths, then verifies the mesh alternative weight as well.
