TR4 TR5 PV4 PV5 Roofing Sheet Roll Forming Machine

The ZTRFM TR4 TR5 PV4 PV5 Roofing Sheet Roll Forming Machine is an automatic production line developed for manufacturing popular trapezoidal metal roofing and wall panels used in Peru and other Latin American markets.

The machine can be designed for TR4, TR5, PV4, PV5 and similar roofing profiles according to customer drawings. It is suitable for roofing sheet manufacturers, construction material suppliers and steel processing factories that require stable continuous production and flexible profile customization.

Finished panels are widely used for industrial buildings, warehouses, workshops, commercial facilities, agricultural structures, residential roofing and wall cladding projects.

Customized Roofing Profiles

Roofing profiles vary between different countries, manufacturers and construction projects. For this reason, ZTRFM designs the forming system according to the customer's actual finished panel drawing instead of limiting the machine to one fixed profile.

Customers can provide detailed drawings for TR4, TR5, PV4, PV5 or other trapezoidal roofing sheets. Our engineers will analyze the rib shape, effective width, side overlap and forming requirements before designing the corresponding rollers.

This customized approach allows manufacturers to produce roofing panels that better match their local market requirements.

Automatic Production Process

The complete production process includes:

Uncoiling → Feeding → Guiding → Roll Forming → Length Measuring → Automatic Cutting → Finished Sheet Receiving

After the steel coil is installed on the decoiler, the material enters the machine through the feeding and guiding section.

The sheet then passes continuously through multiple forming stations. Each roller gradually changes the shape of the material until the required roofing profile is completely formed.

The control system measures the finished sheet length automatically. When the preset length is reached, the cutting system completes the cutting cycle and the finished panel is transferred to the receiving table.

This integrated process helps reduce manual operation and makes continuous batch production easier.

Precision Roll Forming System

The roll forming section is the core part of the roofing sheet production line.

Instead of forming the steel sheet into its final shape at once, the machine gradually completes the deformation through multiple roller stations.

This progressive forming method helps distribute material stress more evenly and improves the consistency of the finished panel.

A properly designed forming system helps maintain:

• Accurate rib shape

• Stable effective width

• Consistent side overlap

• Good panel straightness

• Smooth finished surface

• Reliable installation performance

The forming rollers are precision machined from high-quality steel and can receive surface treatment to improve wear resistance and long-term durability.

Protecting the Coated Steel Surface

TR4, TR5 and PV series roofing panels are commonly produced from coated steel materials.

During production, protecting the painted or galvanized surface is important because excessive friction may affect the appearance of the finished product.

The roller system is designed with smooth contact surfaces to help the steel sheet move through the forming stations more smoothly.

According to different material requirements, additional guiding rollers and lubrication solutions can also be integrated to further reduce unnecessary friction during production.

Strong Machine Structure

The main forming machine uses a heavy-duty steel structure designed for continuous industrial operation.

A stable machine frame provides reliable support for the shafts, forming rollers and transmission components.

Good structural rigidity helps maintain roller alignment during production and reduces unnecessary vibration, which is especially important when producing long roofing sheets.

The machine frame and forming structure can also be optimized according to the required roofing profile and actual raw material.

Suitable Roofing Materials

The production line can process several materials commonly used in metal roofing manufacturing, including:

• PPGI pre-painted galvanized steel

• PPGL pre-painted Galvalume steel

• Galvanized steel

• Aluzinc / Galvalume steel

• Color-coated steel coils

Different materials have different hardness, strength and coating characteristics.

Before manufacturing the machine, customers are encouraged to provide their actual raw material information so that the forming system can be designed according to real production conditions.

PLC Automatic Control

The production line is equipped with a PLC control system and touch-screen operating interface.

Operators can enter the required finished panel length and production quantity directly through the control panel.

During operation, the system automatically coordinates roll forming, length measurement and cutting.

This simplifies daily production management and makes it easier to manufacture different panel lengths according to individual construction projects.

The operating language, electrical configuration and machine voltage can also be customized according to customer requirements.

Automatic Cutting System

After the steel sheet has completed the forming process, it enters the automatic cutting section.

The cutting unit is designed according to the finished roofing profile so that the panel maintains its shape during cutting.

The system works together with the PLC and length measuring device. Once the required length is reached, the machine automatically performs the cutting operation.

This reduces manual measurement and improves consistency during batch production.

Wide Range of Applications

TR4, TR5, PV4 and PV5 roofing panels can be widely used for:

• Industrial factory roofing

• Warehouses

• Workshops

• Commercial buildings

• Agricultural buildings

• Residential houses

• Steel structure projects

• Prefabricated buildings

• Roofing systems

• Exterior wall cladding

Different colors and surface finishes can be produced simply by changing the raw material coil.

Flexible Production Line Configuration

ZTRFM can provide different auxiliary equipment according to the customer's required automation level.

Available options can include:

• Manual or hydraulic decoiler

• Coil loading trolley

• Automatic feeding system

• Servo tracking cutting

• Finished sheet receiving table

• Automatic stacking system

Customers can choose the appropriate configuration according to their production capacity, workshop layout and investment plan.

Factory Testing and Quality Control

Before shipment, the complete production line can be assembled and tested in the factory.

Trial production is used to inspect material feeding, roller alignment, profile forming, transmission operation, electrical control and cutting performance.

The finished roofing panel is checked against the confirmed drawing to ensure that the machine produces the required profile.

Customers can also provide their own raw material for testing when necessary.

OEM and Customized Production Solutions

ZTRFM provides OEM, ODM and customized roll forming solutions for different roofing markets.

Customers only need to provide their finished panel drawing, raw material information and production requirements. Our engineering team can develop a corresponding machine solution based on the actual product.

Whether the required product is TR4, TR5, PV4, PV5 or another customized trapezoidal roofing profile, the production line can be designed around the customer's specific manufacturing needs.

After-Sales Technical Support

ZTRFM provides technical support for machine installation, commissioning, operation and maintenance.

Customers can receive operating instructions, electrical documentation, remote technical assistance and troubleshooting support.

Engineer installation and commissioning services can also be arranged according to project requirements.

With flexible profile customization, automatic production and reliable forming technology, the ZTRFM TR4 TR5 PV4 PV5 Roofing Sheet Roll Forming Machine provides a practical solution for metal roofing manufacturers serving Peru and other Latin American markets.
