Guard rail roll forming machine
The XINNUO XN-W3.0 is a professional-grade roll forming system dedicated to the production of high-standard W-beam (2-wave) highway guardrails. Built for durability and precision, this machine handles 3.0mm thickness material with a yield strength of 235MPa. It features a reinforced 450H steel frame and a robust 100mm solid shaft system driven by dual 11kW motors. With 3 sets of integrated punching functions and a hydraulic cutting system, the XN-W3.0 provides a complete, automated solution for manufacturing road safety barriers that meet international infrastructure requirements.
Product Overview
This XINNUO dedicated W-beam production line is engineered for manufacturers who focus on the most widely used 2-wave highway guardrail profile. By utilizing a high-torque dual-motor drive system and oversized 100mm solid shafts, the machine ensures stable forming of thick galvanized coils without profile drift. The integrated pre-cutting and 3-station punching units allow for the continuous production of finished panels with exact hole alignment, ready for immediate site installation.
Main Features
- Dual 11kW Motor Drive: Powered by two 11kW main motors (22kW total) to provide the necessary torque for consistent forming of 3.0mm high-strength steel.
- 100mm Solid Shafts: High-grade 40Cr solid shafts with a 100mm diameter ensure zero bending and maximum accuracy during high-load production.
- 3-Set Integrated Punching: Features 3 dedicated hydraulic punching stations for bolt holes and connection slots, ensuring perfect compatibility with international guardrail standards.
- Heavy-Duty 450H Frame: Built on a specialized 450H steel frame with 25mm medium plate structures, providing a vibration-free platform for long-term industrial use.
- GCr15 Premium Rollers: Rollers are manufactured from GCr15 bearing steel, precision-machined and heat-treated for exceptional wear resistance and smooth surface finish.
- 2.5-Inch Chain Transmission: Utilizes a heavy-duty 2.5-inch industrial chain to transfer power efficiently across all 15 forming stations.
