Description of double layer roll forming machine
Double Layer Roll Forming Machine can separate produce corrugated roof and IBR roof in one line or similar two profiles. Automatically cut to length, PLC control, alternating Current Frequency Conversion. This line consists of un-coiler, guiding and feeding device, DUAL LEVEL roll former, run out table, PLC controller, hydraulic post-cutting equipment, electrical control system, hydraulic system, etc.
Application
The products are widely used in building the steel-structure large-scale warehouse, plants, supermarkets, shopping malls, trade markets, stadiums, holiday villages, sanatoriums, hotels, villas, residences, and different kinds of greenhouses.
Advantage
The double layer roll forming machine is available for two profiles roof panel shared one frame, save the cost. Double layer roll forming machine
1) Used to produce different roof panels and wall panels
2) Produced panels have such advantages as below: a) Fine profile b) Attractive color c) Agile connecting d) Slightly curved
3) dual-level roll forming machine
4) We can design and manufacture different type of it to hit your particular profiles
