What Is Double Layer Roll Forming Machine?
This machine is mainly used to make metal roofing sheets. Up layer produces one profile, and down layer produces another profile.
|Up Layer||Down Layer|
|Double Layer Machine 1||Trapezoidal Sheet A||Trapezoidal Sheet B|
|Double Layer Machine 2
||Corrugated Sheet A||Corrugated Sheet B|
|Double Layer Machine 3||Trapezoidal Sheet||Corrugated Sheet|
|Double Layer Machine 4||Metal Tile Sheet||Trapezoidal Sheet|
|Double Layer Machine 5||Metal Tile Sheet||Corrugated Sheet|
* Work process is the same as a or a .
* Two layers can not work at the same time.
Why Customer Prefer To Double Layer Machine?
● Save Cost
Two layers share the same machine base, electric motor, hydraulic station.
● Save Floor Area
Commonly, BELI metal sheet roll forming machines are 8-10 meters long. Some of our clients are small factories with limited space. This design of double layer machine solves the trouble of limited factory space and meet clients' requirement on production.

1. What Profiles Can Be Produced In A Double Layer Machine?
* Roll forming steps difference should be in 3-5 steps.
2. Can 3 Profiles Be Produces In 1 Machine?
* We do not suggest 3 profiles in 1 machine, such design will add great difficulty in machine maintenance.
3. How Much Can Clients Save?
* Two layers share the same machine base, motor, hydraulic station, etc.
4. Can 2 Profiles Produce At The Same Time?
* Up layer stop working when down layer works; down layer stop working when up layer works.
5. Do you equip pre-cutting device?
* Yes, we equip electric or manual pre-cutting device for easy cutting material less than 0.6mm thickness.
