TR4 Aluzinc Roofing Sheet Roll Forming Machine | Automatic Line

The ZTRFM TR4 Aluzinc Roofing Sheet Roll Forming Machine is an automatic production line specially designed for manufacturing TR4 trapezoidal metal roofing and wall panels. This roofing profile is widely used in Peru and other Latin American markets for industrial buildings, warehouses, workshops, commercial facilities, agricultural buildings and residential roofing projects.

The machine combines automatic feeding, precision roll forming, length measuring and cutting into one continuous production process. It is suitable for roofing sheet manufacturers, building material suppliers and metal processing factories looking for stable production, easy operation and customized profile solutions.

Professional TR4 Roofing Sheet Production

TR4 is a popular trapezoidal roofing profile in the Peruvian construction market. Its raised ribs provide good structural rigidity while keeping the finished sheet lightweight and convenient to transport and install.

Different manufacturers may have slightly different TR4 profile dimensions. For this reason, ZTRFM can design the machine according to the customer's own finished panel drawing rather than limiting production to only one standard profile.

Customers can provide a detailed drawing showing the rib shape, effective width and overlap dimensions. Our engineering team can then design the forming rollers according to the required finished product.

Automatic Production Process

The complete production process includes:

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

After the Aluzinc or color-coated steel coil is loaded onto the decoiler, the sheet enters the production line through the feeding and guiding section.

The material then passes continuously through multiple forming rollers. Each roller gradually changes the sheet until the complete TR4 trapezoidal profile is produced.

The control system automatically measures the finished sheet length. When the preset length is reached, the cutting system completes the cutting operation and the finished roofing panel is discharged to the receiving section.

This continuous process reduces manual operation and makes batch production easier to manage.

Precision Roll Forming System

The roll forming section is the core of the TR4 roofing sheet production line.

Instead of forming the steel sheet into its final shape in one step, multiple forming stations gradually complete the deformation.

This progressive forming process helps distribute material stress more evenly and contributes to stable rib dimensions, accurate panel width and good finished sheet straightness.

The forming rollers are precision machined according to the confirmed TR4 profile. High-quality roller surfaces help maintain stable forming performance during continuous production.

The roller design also focuses on reducing unnecessary friction with the coated steel surface, which is particularly important when processing Aluzinc and pre-painted roofing materials.

Suitable for Aluzinc Roofing Materials

Aluzinc is widely used for metal roofing because it combines the protective properties of aluminum and zinc coatings with the strength of steel.

The TR4 production line can also process other suitable roofing materials such as PPGI, PPGL, galvanized steel and color-coated steel coils.

Different materials may have different strength and forming characteristics. Customers can therefore provide their actual coil information before machine manufacturing so that the forming system can be designed according to real production conditions.

Strong and Stable Machine Structure

The main roll forming machine uses a strong welded steel structure designed for continuous industrial operation.

A rigid frame provides reliable support for the shafts, forming rollers and transmission components. Stable machine construction helps keep the forming stations correctly aligned and reduces unnecessary vibration during production.

This is particularly important when manufacturing long roofing sheets because good machine stability directly affects finished panel straightness and installation quality.

The machine structure can also be optimized according to the customer's raw material and production requirements.

Material Feeding and Guiding System

Correct material feeding is important for maintaining consistent TR4 profile quality.

The feeding section guides the steel sheet into the first forming station in the correct position. Roller-type guiding components help the material move smoothly into the machine while reducing unnecessary contact with the coated surface.

Accurate feeding helps maintain consistent rib position, effective panel width and side overlap throughout continuous production.

PLC Automatic Control

The production line is equipped with a PLC control system and convenient operating interface.

Operators can enter the required finished sheet length and production quantity through the control panel. The machine then automatically coordinates forming, length measurement and cutting.

This simplifies daily operation and allows different production orders to be managed more efficiently.

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

Automatic Cutting System

After the TR4 roofing sheet has completed the forming process, it enters the automatic cutting section.

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

The cutting blade is designed according to the finished TR4 profile to maintain the shape of the roofing panel during cutting.

Automatic measuring and cutting help reduce manual work and improve consistency during batch production.

Wide Range of Applications

TR4 Aluzinc roofing sheets produced by this machine can be used for:

• Industrial factories

• Warehouses

• Workshops

• Commercial buildings

• Agricultural buildings

• Residential roofing

• Steel structure projects

• Prefabricated buildings

• Exterior wall cladding

Different colors and surface finishes can be produced by changing the raw material coil, allowing roofing manufacturers to serve different construction projects and market requirements.

Customized Production Solutions

ZTRFM provides OEM, ODM and customized roll forming solutions.

Customers can send their TR4 or other trapezoidal roofing profile drawings, raw material information and production requirements. Our engineering team can design a suitable production line based on the actual product.

Customization can include the roofing profile, feeding system, forming structure, cutting method, control system, decoiler and finished product handling equipment.

Optional hydraulic decoilers, coil loading trolleys, receiving tables and automatic stacking systems can also be added according to the required automation level.

Factory Testing and Quality Control

Before shipment, the complete TR4 production line can be assembled and tested at the factory.

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

The finished roofing sheet is compared with the confirmed profile drawing before delivery.

Customers can also provide their own Aluzinc or color-coated steel coils for machine testing when required.

After-Sales Technical Support

ZTRFM provides technical support covering installation, commissioning, operation and maintenance.

Customers can receive operating instructions, electrical documentation, remote technical guidance and troubleshooting support. Engineer installation and commissioning services can also be arranged according to project requirements.

With customized TR4 profile design, automatic production and stable roll forming technology, the ZTRFM TR4 Aluzinc Roofing Sheet Roll Forming Machine provides a practical production solution for roofing sheet manufacturers serving Peru and other Latin American markets.
