Maximum Arc Lengths

Bars that exceed the radius values below are to be supplied straight.

 

Bar Size (mm) Radius (M)
6 2.5
8 2.75
10 3.5
12 4.25
16 7.5
20 14.0
25 30.0
32 43.0
40 58.0

Notes:

  • The required curvature may be obtained during placing.
  • For shapes with straight adn curved lengths (Shapes 12, 13, 22, and 33), the largest practical radius for the production of a continuous curve is 200 mm. For larger radii, the curve may be produced by a series of straight sections.
