TR4 and TR5 double layer roll forming machine

TR4 and TR5 Double Layer Roll Forming Machine: Complete Enterprise Solution

The TR4 and TR5 double layer roll forming machine is your answer. This advanced cold-forming system produces two distinct trapezoidal profiles—4-rib and 5-rib configurations—in one compact vertical unit. You'll save approximately 50% of floor space compared to running two separate lines. Our machine features 16+18 roller stations, 80mm solid shaft construction, and processes 0.3-0.8mm steel at speeds up to 25m/min with ±1mm cutting precision. Backed by ISO 9001 certification and proven in over 150 countries, it's the versatile solution for pre-engineered building manufacturers.

Why Choose Double Layer Technology?

Your factory faces constant pressure. You need more output but can't afford larger facilities or double equipment investments.

That's where our dual-layer design changes everything.

Space-Saving Innovation

Traditional production requires separate machines for different profiles. You're looking at double the footprint, double the investment, and complex workflow coordination.

Our vertical stacking architecture combines two complete forming systems into one frame. The upper layer handles TR5 profiles while the lower processes TR4 sheets. Both share a unified motor and control system.

Real impact for your business:

·  50% reduction in required floor space

·  Single power connection instead of two

·  One operator can manage both production lines

·  Lower electrical consumption per unit produced

Financial Advantages

Your capital goes further with consolidated equipment. Instead of purchasing two complete machines, you invest in one integrated system.

The cost benefits extend beyond initial purchase. You'll reduce ongoing expenses across maintenance, spare parts inventory, and operator training.

Technical Specifications That Matter

Material Compatibility

You can process multiple metal types without equipment changes:

·  PPGI (Pre-painted Galvanized Iron) – for color-matched roofing

·  GI (Galvanized Iron) – standard corrosion protection

·  GL (Galvalume/Alu-zinc) – enhanced rust resistance for coastal areas

·  AI (Aluminum) – lightweight applications

Thickness range: 0.3mm to 0.8mm

Yield strength: up to G550

How Your Production Benefits

For Pre-Engineered Building Manufacturers

Your projects demand both roofing and wall cladding profiles. The TR5 configuration provides superior load-bearing for roofs with deeper ribs for water drainage. Meanwhile, TR4 sheets serve perfectly for wall applications.

With our TR4 and TR5 double layer roll forming machine, you switch between profiles using a simple clutch system. No roller changes. No production line downtime. Just select the layer and start forming.

For High-Volume Operations

Speed matters when you're fulfilling large contracts. Our machine maintains consistent quality at 25 meters per minute.

The automated length measurement system eliminates manual measuring errors. Set your desired length in the PLC, and the encoder tracks material feed with precision. The hydraulic shear activates automatically, delivering perfectly cut sheets.

For Site-Based Production

Large-span projects often face transport limitations. Standard trucks restrict panel lengths to 12 meters, forcing multiple joints during installation.

Our compact dual-layer design fits into containerized mobile units. You can transport the product directly to construction sites, producing panels at any length the project requires. This eliminates transport restrictions and reduces installation joints for superior weather sealing.

Quality Standards You Can Trust

As a national-level high-tech enterprise established in 2014, we manufacture every machine to international standards:

·  ISO 9001 certified quality management

·  CE certification for European safety compliance

·  CAS certification meeting North American standards

Our partnership with Yanshan University's National Cold Rolled Strip Equipment Engineering Research Center brings cutting-edge technology into every machine. We use finite element analysis and AI-assisted simulation to optimize roller design before manufacturing.

What Quality Looks Like

When your machine arrives, you'll notice the difference immediately:

Profile Precision: Sheets produced hours apart interlock perfectly. Our synchronized roller system maintains exact rib spacing, ensuring weather-tight installation.

Surface Protection: The hard chrome-plated rollers never mark your pre-painted materials. Speed synchronization prevents coating damage that cheaper machines cause.

Clean Cutting: The hydraulic shear delivers deformation-free cuts. Your sheets maintain perfect rib shape right to the edge—no installation failures or aesthetic rejections.

Consistent Operation: Run continuously for full shifts without temperature issues. Our hydraulic systems stay below 60°C, and the PLC maintains accurate length readings without drift.

Complete Production Line Components

Hydraulic Decoiler

Smooth material feeding prevents surface scratches and ensures consistent tension. The hydraulic system adjusts automatically to coil diameter changes.

We include a manual decoiler as a free backup unit for your operational flexibility.

Main Forming Section

The heart of your production features dual roller sets:

·  Upper layer: 18 forming stations for TR5 profiles

·  Lower layer: 16 forming stations for TR4 profiles

Each station gradually shapes the material, preventing stress points that cause cracking or warping.

Cutting System

Hydraulic post-cutting with Cr12MoV steel blades delivers thousands of cuts before blade replacement. The system processes your programmed quantities automatically.

Control Panel

The industrial-grade PLC interface is intuitive. Your operators will master it quickly. Program length, quantity, and cutting patterns through the touchscreen. The system remembers settings for different profiles, making switching effortless.

Frequently Asked Questions

Can I produce both profiles simultaneously?

No, the machine produces one profile at a time. The clutch system activates either the upper or lower roller set. This design ensures power efficiency—you only drive the active layer.

How long does switching between TR4 and TR5 take?

Switching is instantaneous. Simply select the desired layer through the PLC control panel. There's no physical roller change required.

What maintenance does the machine require?

Regular maintenance is straightforward. Lubricate the chain drive monthly. Check hydraulic fluid levels weekly. The chrome-plated rollers typically last 5+ years before requiring replacement.

Can the machine handle thicker materials than 0.8mm?

The standard configuration processes up to 0.8mm. If your application requires thicker materials, we can customize the shaft diameter and roller strength during manufacturing. Contact us with your specific requirements.

What power supply does it need?

Standard configuration operates on 380V three-phase power. We can modify electrical specifications to match your regional power standards.

How do you ensure the machine arrives undamaged?

We use reinforced export packaging with steel frames. Critical components receive additional protection. Our logistics team has successfully shipped to 150+ countries with minimal damage incidents.

Do you provide installation support?

Yes. We offer multiple support levels: detailed installation manuals with diagrams, video call guidance during setup, and on-site installation services for an additional fee. Our technical team can travel to your facility.

What's included in the warranty?

We provide a one-year warranty covering manufacturing defects. The warranty includes roller stations, hydraulic systems, and control components. Wear parts like cutting blades are excluded.

Can I visit your factory before purchasing?

Absolutely. We welcome factory visits. You can see machines in production and test operation. We're located in Cangzhou, easily accessible from Beijing. Contact us to schedule your visit.

What training do you provide for operators?

We supply comprehensive operation manuals and video tutorials. For on-site installation services, our technicians provide hands-on training for your operators during commissioning.
