how can we calculate cutting length of a column ring
(300 x 600)

Answer Posted / amit dutta

Column size 300 × 600 mm.
Column cover 40 mm.
Column hook 10d.
Column strip 8 mm.
2×(300-80+600-80)+10*8
1480+80 mm= 1560 mm.
Now deducted due to 90 degree bend 2d and 135 degree for 3d
So now total cutting length of strip is
1560 -72mm =1488 mm =1490 mm
