I. Technological Leadership: Core Competitiveness of Intelligent Roll Forming Equipment
1. Intelligent Switching & Flexible Production
- One-Key Profile Switching: Achieves seamless transitions between C/Z purlin profiles within 3 minutes via PLC control and coaxial sliding sleeve technology.
- High-Speed Output: Operates at 30 meters/minute with servo hydraulic cutting (±1.0mm precision), outperforming traditional purlin machines.
- Material Compatibility: Supports galvanized steel and high-strength steel (thickness: 1.5 - 5.0mm) with adjustable input widths.
Technical Specifications – C & Z Purlin Width Ranges
| Profile Type | Standard Width (mm) | Medium Width (mm) | Heavy Width (mm) |
| C-Type | C100-300 | C150-350 | C250-550 |
| Z-Type | Z120-300 | Z150-350 | Z200-450 |
Thickness range: 1.5–5.0 mm. Forming speed: 30 m/min. Cutting precision:±1.0 mm.
2. Precision Manufacturing of Core Components
- Frame: H-beam (450/600) processed via 13-meter gantry milling for cutting accuracy.
- Wall Plates: Modular insert design (thickness: 28 - 43mm), sandblasted and coated with anti-rust paint for extreme environments.
- Roller Process:
- Material: Cr12 steel (HRC58-62 hardness) for extended roll forming durability.
- Production Steps: Cutting → Rough Turning → Heat Treatment → Grinding → Precision Turning.
- Shaft & Sleeve:
- Shaft: 45# steel with quenched/tempered treatment and hard chrome plating for wear resistance.
- Sleeve: 45# steel with hard chrome plating, ideal for high-temperature/humidity environments.
3. Energy Efficiency & Sustainability
Servo motors & variable frequency drives reduce energy consumption through closed-loop control.
II. Industry Empowerment: Full-Scenario Applications & Custom Services
- Industrial Workshops: C-purlin systems enable rapid installation of color steel panels.
- Stadiums: Z-purlins provide column-free structural support.
- Modular Buildings: G-purlins minimize bolt usage, boosting construction efficiency.
Agricultural Innovations
Smart Greenhouses: Modular purlin machine systems enhance load-bearing capacity and assembly speed.
Custom Solutions
- Non-Standard Designs: Custom holes, stiffeners, and adjustable hole spacing.
- Global Reach: CE-certified CZ purlin roll forming machine exports with technical support across 100+ regions.
