R101 Roofing Sheet Making Machine

R101 Roofing Sheet Making Machine – Precision Cold Roll Forming Equipment

Cangzhou Zhongtuo Roll Forming Machinery Co., Ltd. delivers enterprise-grade R101 Roofing Sheet Making Machine solutions engineered for high-volume industrial production. This cold roll forming system processes 0.3–0.8 mm galvanized and prepainted steel coils through 18 precision forming stations, achieving line speeds up to 15 m/min with ±2 mm cutting accuracy. Powered by a robust 5.5 kW main motor and Delta PLC touchscreen control, the machine maintains consistent profile tolerances across extended production runs. The heavy-duty 16 mm H-beam frame and 70 mm solid steel shafts ensure structural stability during continuous operation, making it ideal for large-scale roofing manufacturers.

Core Advantages You Can Rely On

Superior Roller Engineering

We use GCr15 bearing steel for all forming rollers, hard chrome plated to 0.05 mm thickness. This surface treatment extends roller life significantly while preventing damage to prepainted coatings during forming.

Intelligent Production Control

The Delta PLC system allows you to preset sheet length and quantity with automatic counting. The touchscreen interface simplifies operation, reducing training time for your production staff.

Precise Hydraulic Cutting

Our Cr12MoV mold steel cutting blade undergoes heat treatment to HRC 58-62 hardness. This ensures clean cuts without burrs across hundreds of thousands of production cycles before maintenance becomes necessary.

Versatile Material Compatibility

Whether you work with PPGI, galvanized steel, or aluminum-zinc coated materials, this machine handles various coating types without surface scratching. The gradual forming process through 18 stations minimizes material stress.

Technical Specifications of R101 Roofing Sheet Making Machine

Industrial Applications

Pre-Engineered Building Projects

Your construction clients benefit from R101 profiles that offer excellent water drainage and structural strength. The trapezoidal design supports wider purlin spacing, reducing overall project costs while maintaining load-bearing capacity.

Agricultural Facility Roofing

For barns, livestock shelters, and storage buildings, this R101 Roofing Sheet Making Machine produces corrosion-resistant roofing that withstands ammonia exposure and high humidity environments. The protective coatings remain intact throughout the forming process.

Residential Roofing Supply

Government housing projects and residential developments require high-volume production capabilities. You can fulfill large orders quickly while maintaining consistent quality standards that meet local building codes.

Quality Manufacturing Process

Material Feeding & Alignment

The 5-ton decoiler maintains steady tension as coil material feeds into the machine. An adjustable leveling unit removes coil set before material enters the forming stations.

Progressive Forming Stations

Each of the 18 stations gradually shapes the flat steel into the R101 profile geometry. This incremental approach prevents material cracking and maintains dimensional accuracy across the entire sheet length.

Automated Length Control

Your operators set the desired length on the PLC touchscreen. The encoder-based measuring system triggers the hydraulic shear at precisely the right moment, eliminating manual measurement errors.

Quality Output

Finished sheets exit with consistent rib height, wave pitch, and effective coverage width. The profile maintains flatness without twisting or bowing when properly calibrated.

Why Partner With Zhongtuo

Since 2014, we've specialized in cold roll forming technology with backing from Yanshan University's National Cold Rolled Strip Equipment and Process Engineering Research Center. Our R&D team uses finite element analysis and AI-assisted simulation to optimize roller designs before manufacturing.

We hold ISO 9001 certification for quality management and European CE safety certification. These aren't just compliance documents—they represent our commitment to consistent manufacturing standards that protect your investment.

Our machines operate in over 150 countries across Europe, North America, the Middle East, Southeast Asia, and South America. This global presence means we understand regional power requirements, material preferences, and technical standards that affect your production.

Strategic cooperation with Siemens enhances our control system capabilities. We integrate proven automation components that your maintenance teams can service reliably.

Packaging & Delivery

Standard export packaging includes plastic film wrapping for moisture protection and wooden case reinforcement for ocean freight. Main machine components ship fully assembled to minimize installation complexity at your facility.

Critical wearing parts like cutting blades and a complete set of adjustment tools are included. We provide both English operation manuals and video tutorials covering setup, operation, and troubleshooting procedures.

FAQ

Q：What material grades can this machine process?

A：The standard configuration handles G300 to G450 yield strength steel. If you need to form G550 full-hard material, we recommend upgrading to reinforced forming stations and higher motor power to compensate for spring-back characteristics.

Q：How long do cutting blades typically last?

A：With proper hydraulic oil maintenance and correct cutting gap adjustment, expect 500,000 to 1 million cuts before blade sharpening becomes necessary. Actual lifespan depends on material thickness and hardness.

Q：Can you customize the profile dimensions?

A：Yes. While this model produces the standard R101 geometry, we design custom roller sets for modified rib heights or different effective widths based on your market requirements. Custom roller tooling typically adds 2-3 weeks to delivery schedules.

Q：What maintenance does the machine require?

A：Change hydraulic oil after the initial 6-month break-in period, then annually. Keep roller surfaces clean to prevent material marking. Check chain tension monthly and lubricate guide rails weekly during active production periods.

Q：Do you provide installation support?

A：We offer remote commissioning support via video guidance and can dispatch technicians for on-site installation if needed. Most customers with basic mechanical knowledge complete installation independently using our detailed manual.

Q：How does this compare to competitors' machines?

A：Our product uses thicker frame construction and larger shaft diameters than many comparable models. This extra rigidity maintains profile accuracy even after years of continuous operation, reducing adjustment frequency.
