Product Details


Double layer mrtal 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-shape roof panel, etc.

Main advantages of this double layer design is 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 double floor area. This double layer machine design is a good choice for clients who need to enlarge production while with limited space.
