Generate BBS tables with cutting lengths, bend deductions (IS 2502), lap lengths, and weight calculations.
Add multiple bar groups and export the complete schedule.

This BBS calculator uses standard IS 2502 bend deductions and IS 456 lap length formulas. For complex shapes, crank bar geometry, or bundled bars, verify manually against approved drawings. Always cross-check with site measurements before ordering steel.
