  • For RCC column the cover should be 25 mm to 40 mm depending on the size of steel bar and on thickness of the column also.
  • In case of footing of column or walls, the cover shall be 50 mm to 75 mm .
  • In case of beams the cover should be 25 mm to 40 mm (1 to 1.5) depending on the size of steel bars.
