Bullnoses & Center Cranks

Bullnosing and centre-cranking of a profiled sheet incorporate lateral rib indentations pressed in at a uniform distance of 25 mm. Standard bullnoses are made with narrow flute uppermost and the bend away from the angular inclination. Reverse bullnoses are made with the bend into the narrow flute. Bullnoses and cranks can be at the end of a sheet or at any position along the length. Bullnoses and centre cranks can be manufactured in radii ranging from 350 mm to 800 mm for bullnoses which are bent through 0 – 135°. High tensile material can only be bullnosed and cranked to a minimum radius of 450 mm.
