High Precision Double Layer Roof Panel Roll Forming Machine Two years

ZTRFM specializes in the development, manufacturing and customization of cold roll forming equipment, providing efficient and stable metal forming solutions for customers worldwide.

According to different roofing profiles, raw material specifications and actual production requirements, the forming system, roller arrangement, cutting system, control system and complete production line can be customized accordingly.

The Double Layer Roll Forming Machine adopts an upper and lower double-layer forming structure. Two independent forming roller systems are integrated into one machine, allowing two different roofing profiles to be produced on a single production line.

Compared with installing two separate roll forming machines, the double layer design helps reduce factory floor space and equipment investment while providing greater production flexibility. It is suitable for manufacturers of steel structures, metal roofing sheets and building materials.

Key Advantages

Two Profiles in One Machine
The upper and lower levels are equipped with independent forming roller systems, allowing two different roofing profiles to be produced on one machine.

Space-Saving Double Layer Design
Two forming systems are integrated into one main frame, reducing the required installation area compared with two separate production lines.

PLC Automatic Control
The PLC and touch screen control system allows operators to set production length and quantity, with automatic length measurement, counting and cutting.

Stable Forming System
The number of forming stations, roller structure and forming sequence are designed according to the confirmed profile drawing to achieve stable and consistent sheet forming.

Hydraulic Cutting System
The hydraulic cutting system automatically cuts the finished sheet according to the preset production length, providing convenient and reliable operation.

Customized Production Solution
The machine can be customized according to the customer's CAD drawing, dimensional drawing or physical sample, including profile design, roller arrangement, machine dimensions, voltage and production line configuration.

Applicable Materials

The Double Layer Roll Forming Machine can be used for processing:

PPGI, GI, prepainted steel, galvanized steel and other metal sheets suitable for cold roll forming.

The forming system can be designed according to different material thicknesses, coil widths and finished roofing profiles to meet different production requirements.

Applications

Roofing sheets produced by the Double Layer Roll Forming Machine can be widely used for:

Industrial workshops, steel structure buildings, warehouses, factories, commercial buildings, agricultural buildings and various metal roofing projects.

For manufacturers that need to produce two different roofing profiles, the double layer design provides a practical solution for improving equipment utilization while reducing workshop space requirements.

ZTRFM Customized Service

ZTRFM can design the machine according to the customer's profile drawing, dimensional drawing, CAD drawing or physical sample.

Our technical team first analyzes the required profile, material thickness, coil width and finished dimensions before preparing the corresponding forming solution. After the profile design is confirmed, the forming stations, roller arrangement, cutting system and complete machine configuration are determined accordingly.

In addition to machine manufacturing, ZTRFM can provide:

Installation guidance, operation training, technical support, equipment commissioning and remote PLC diagnostic services to help customers solve operating problems efficiently.

ZTRFM is committed to providing efficient, stable and reliable cold roll forming equipment solutions for customers worldwide.
