Sometimes when a client needs to produce two different metal sheets, cladding, trapezoidal, corrugated sheets or metal tiles, a double layer roll forming machine always comes to mind.

Compared to a single layer roof panel roll forming machine, a double layer roll forming machine is desgined to produce two different kinds of metal sheets which can be one trapezoidal roofing and one roof/wall cladding sheet; or one trapezoidal roofing sheet and one corrugated roofing sheet; or one trapezoidal sheet and one metal roof tile; or one corrugated sheet and one metal glazed roof tile etc. To sum up, any two of the metal roof panels can be produced by this same double deck roll forming machine.

Brief introduction of double layer roll forming machine:

Double layer roll forming machine

A double layer roll forming machine has two layers or two levels of roll forming parts which gives it another name dual level roll forming machine, and because this machine makes two metal sheets, and double sheet roll forming machine is also a familiar name to people. (Similar machines are like two-in-one roll forming machine and cassette type roll forming machine.)

It shall be pointed out that the two layers of roll forming parts on this double layer roll forming machine cannot work at the same time, which means each one of the roll forming systems (top roll forming and bottom roll forming) will stop when the other is working. The two layer or two levels roll forming parts share a same motor and the change of running between top and bottom roll forming part is made through a clutch equiped on this double deck roll forming machine.
