Dupral is able to produce a wide variety of special products:
Rolled covers are produced to the required radius using a 3-roller rolling mill. It is also possible to produce conical products. Additional forming work on the rolled cover is of course also possible.
Covers can be made from steel, aluminium, copper and zinc. Maximum thickness is 3.0 mm.
Cassettes are punched from flat sheets and are then formed. They can be produced to any required size, including corner sections to any required angle.
Assembly is fairly simple because only the top needs to be fixed, with the next section being placed on top of the section just fixed (male/female).
For larger sizes there is the option of bonding Eps to the inside, which results in a smoother appearance. Maximum thickness is 3.0 mm.
Corner sections of every imaginable angle – both internal and external – can be made from any required profile.
