CRANKING OF PROFILED SHEETING

Cranking of a profiled sheet incorporates lateral rib indentations pressed in at uniform distances which vary according to the radius requirements.

Cranked sheets can be supplied in standard radii as follows:

Profile

Std.
Radius (inside curve)


760
300mm 400mm 450mm 500mm

686 (IBR)

300mm 400mm 450mm 500mm

610/762
300mm 400mm 450mm 500mm

700
      500mm

STANDARD CRANK (686 & 760)

Normally with the narrow flute uppermost and the bend away from the angular inclination.

REVERSE CRANK (686 & 760)

Normally with the narrow flute downwards and the bend into the narrow flute. Cranks can be at the end/ends of a sheet or at any position along the length.

Note: All profiles can be cranked in Full Hard and commercial quality material but only to a minimum radius of 300mm.
