Dupral also specialises in producing straight and curved sandwich panels.
We are also at an advanced stage of being able to bend insulated roofing panels, for which a number of projects have already been undertaken.
Sandwich panels can be produced to almost any required angle (1° to 180°), both as regards length and width as well as internal and external.
The angle is sawn and formed. The sawn panels are formed to the required angle, after which a diagonal is secured using blind-rivets in order to maintain the angle.
Sandwich panels can be produced to almost any required radius.
The required radius is created by sawing a number of incisions. The sawn panel is placed in a jig with the required radius.
The radius is maintained by blind-riveting two narrow strips into the lined inner plate.
