Double layer metal roofing sheet roll forming machine has two layers of roller stations. Each layer of roller station is for producing one roofing profile such as trapezoidal sheet, corrugated sheet, IBR sheet, tile-shaped roof panel, etc.

Double Layer Roll Forming Machine could use in the construction of warehouses, workshops, hangars, barracks, equipment storage, gymnasium, and low-cost housing, also in the production of boats, vehicles, and highway guardrails, etc.

This type of Double Layer Roll Forming Machine has an advantage including beautiful, classical appearance and grace taste. 

It can be widely used in village, hotel, exhibition, vacation village, family construction and outdoor decorate.

Main advantages of this double layer design are to save cost and save floor area for clients. 

●   Save Cost

Two layers share the same machine base, electric motor, electric control system and hydraulic station.

●   Save Floor Area

Commonly, one roll forming line will occupy at least 25 square meters (at least 12m long and 2m wide), and two lines will need a double floor area. This double layer machine design is a good choice for clients who need to enlarge production while with limited space.

●   Roll forming process flow

Roll forming, forming step effect, cutting to length, receiving finished products.

Whole Line Work Flow

*   Work process is the same as a plain roofing sheet machine or a metal tile machine.

*   Two layers can not work at the same time.

*   Shared Parts: machine base, motor, hydraulic station, control system.

*   Individual Parts: feeding guide, roller stations, shafts, and rollers, cutting device.
