Bending Schedules

RMS will cut and bend the bar according to the bending schedules supplied by the customer. All bending schedules refer to the standard Shape Codes as per the table shown:

 

SANS 282: Edition 6

  • Note 1: use shape code 99 for all other shapes. A dimensioned sketch of the shape shall be given in the bending schedule.
  • Note 2: Radii of all bends are standard unless r is given in the bending schedule.
  • Note 3: All dimensions are external (outstide) dimensions.

 Cutting & Bending Standards SANS 282:Edition 6

Shape codes 32, 33, 34 and 35 have been removed as they are adequately covered by other shape codes. This brings SA codes in line with British standards.
