T12 Reinforcing Bar

Area per metre width at common spacings

For slab or wall reinforcement specified as “T12@ spacing c/c” — the area provided per unit width at each standard centre-to-centre spacing.

Equivalent options at 150mm spacing

Every metric bar size at the same reference spacing, so you can see at a glance which other size lands near the same area per unit width as T12.

Area and mass are computed directly from the nominal diameter (mass assumes standard steel density, 7850 kg/m³) — the same values the Rebar Calculator uses.
