The ZTRFM TR4 Metal Roofing Sheet Roll Forming Machine is a fully automatic production line specially designed for manufacturing TR4 trapezoidal metal roofing and wall panels.
TR4 roofing profiles are widely used in residential, commercial, industrial and agricultural buildings, especially in South American markets such as Peru.
The machine continuously forms pre-painted galvanized steel, galvanized steel or Aluzinc coils through multiple precision forming rollers. After the required profile is formed, the sheet is automatically measured and cut to the preset length.
The complete production process can be controlled through the PLC touch screen, helping manufacturers achieve stable profile dimensions, consistent sheet quality and efficient continuous production.
The TR4 roofing sheet produced by this machine can be widely used for:
The machine can also be customized according to the customer's own TR4, TR5, TR6 or other trapezoidal roofing profile drawings.
The machine is suitable for processing different types of coated steel coils, including:
Typical material thickness: 0.4–0.6 mm
Other thickness ranges can be designed according to the customer's raw material and profile requirements.
Uncoiling → Feeding → Guiding → Roll Forming → Length Measuring → Hydraulic Cutting → Finished Sheet Receiving
The production line operates automatically after the operator enters the required sheet length and production quantity through the PLC control system.
The main machine uses a heavy-duty welded steel structure to provide sufficient rigidity during continuous production.
A strong machine frame helps reduce vibration and deformation during forming, improving the dimensional consistency of the finished roofing sheets.
Typical structure:
The TR4 profile is gradually formed through multiple roller stations.
For typical TR4 production lines, approximately 20–22 forming stations may be used depending on the confirmed profile drawing and material specification.
The gradual forming design helps reduce:
The final roller design is calculated according to the customer's confirmed TR4 drawing.
The forming rollers are manufactured from high-grade steel and precisely machined to obtain stable forming dimensions.
Typical configuration:
Roller material: High-grade 45# steel
Surface treatment: Hard chrome plated
Processing: CNC precision machining
The chrome-plated roller surface improves wear resistance while helping protect the surface coating of PPGI or PPGL materials.
Each roller is accurately positioned on the shaft to maintain stable forming accuracy during long-term production.
The forming shafts use high-grade solid steel with heat treatment.
Typical configuration:
Shaft material: High-grade 45# steel
Shaft diameter: approximately Φ80 mm or customized
The solid shaft design provides sufficient strength for continuous roof panel production.
Different shaft diameters can be selected according to:
The standard TR4 roofing sheet machine can use a double-chain transmission system.
Compared with a single-chain transmission structure, double-chain transmission provides stronger and more stable power transmission during forming.
Advantages include:
Higher-speed versions can also be designed with gearbox transmission according to production requirements.
The feeding section guides the steel coil into the roll forming section accurately.
Adjustable guiding devices are installed on both sides so that the material can enter the forming rollers in the correct position.
Stainless steel guiding rollers help reduce friction and protect the coated steel surface.
The feeding width can be adjusted according to the confirmed coil width.
After forming, the roofing sheet is automatically cut to the required length.
The machine normally uses a hydraulic post-cutting system.
Typical features include:
A four-pillar cutting structure can also be used to improve cutting stability.
The cutting blade is manufactured from high-strength tool steel and heat treated for improved hardness and service life.
The complete production line is controlled through an industrial PLC system.
Typical electrical configuration includes:
PLC: Delta
Touch Screen: Delta or equivalent industrial brand
Encoder: Omron
Electrical Components: Schneider or equivalent
The operator can enter:
through the touch screen.
After the production order is entered, the machine automatically completes forming, measuring and cutting.
The PLC system can support different operating languages according to customer requirements.
The hydraulic station supplies power for the cutting system.
Typical configuration:
Hydraulic motor: 5.5 kW
Hydraulic oil: No. 46 hydraulic oil
Main components include:
The hydraulic station is designed for reliable continuous industrial operation.
A standard production line can be equipped with a 5-ton manual decoiler.
Typical specifications:
Loading capacity: 5 tons
Coil inner diameter: approximately Φ450–550 mm
Maximum feeding width: approximately 1220 mm
The decoiler supports the steel coil and feeds material continuously into the roll forming machine.
Hydraulic decoilers and automatic loading systems are also available as optional configurations.

Note: Machine specifications depend on the customer's confirmed profile drawing, material thickness and required production speed.
The roller system is designed specifically according to the customer's TR4 profile drawing, helping maintain consistent rib height, sheet width and profile dimensions.
Precision-machined and chrome-plated forming rollers help reduce scratches on PPGI and PPGL materials.
After setting the required length and quantity through the PLC system, forming and cutting can be completed automatically.
The machine normally requires only a small number of operators, reducing manual operation and production complexity.
The double-chain transmission and heavy-duty machine frame provide stable performance during continuous production.
Different machine configurations can be supplied according to:
ZTRFM can customize the roofing sheet machine according to the customer's production requirements.
Available options include:
Customers can send us the roofing sheet profile drawing with dimensions, and our engineers can design the corresponding production solution.
The machine produces trapezoidal roofing panels with strong ribs and stable dimensions.
TR4 roofing panels provide good structural strength while remaining lightweight, making them suitable for large roofing and wall-cladding projects.
The finished sheet can be produced in different colors and lengths according to project requirements.
Before delivery, the production line can undergo complete factory testing.
