Curved profiled sheets
Our semi-patented bending process is now used in 14 countries and is known as crimp-curving. Dupral is able to bend countless different types of profiled sheets into every imaginable radius. Bending to angles ranging from 1 to 180 degrees, with a minimum radius of around 250 mm and a maximum sheet length of 13,000 mm (depending on the radius), and the bending of S-curves, present no problem whatsoever. Corrugated sheets (types 17-76 and 18-76) can also be shaped by means of rolling, without the need for crimp-curving. For new profile sheet designs Dupral is able to produce the necessary crimp-curving in-house.
