trapezoidal metal roof panel roll forming machine

 

The XN‑Trapezoidal series roll forming machine is a new‑generation automatic cold forming equipment independently developed by Hebei Xinnuo Machinery. It is specially designed for manufacturing high‑quality trapezoidal metal roofing and wall panels.

 

Compared with conventional models, this line features heavy‑duty rigid structure, high‑precision forming rollers, intelligent PLC control, and stable high‑speed production. It realizes fully automatic production from coil unrolling, leveling, roll forming, length cutting to final product output. It is widely used in industrial workshops, warehouses, stadiums, commercial buildings and residential construction.

 

Key Advantages

1. High‑Precision Roll Forming System

• 16–24 groups of solid roll stations for smooth, step‑by‑step forming
• Rollers made of 45# forged steel, quenched to HRC 58–62, hard chrome plated
• Large‑diameter 70–75mm solid main shaft, strong rigidity, no deformation during high‑speed operation
• High forming accuracy, stable panel shape, no surface scratches or rebound
• Finished panels with excellent flatness, tight splicing and superior waterproof performance

 

2. Intelligent Automatic Control System

• PLC + touch screen control system (supports Chinese, English, Spanish, French, Portuguese)
• High‑precision encoder for fixed‑length cutting, error ±0.5 mm
• One‑key operation: set length, batch count, production speed, fault diagnosis
• Full safety protection: emergency stop, safety guards, overload protection, door interlock
• Complies with CE safety standards

 

3. Heavy‑Duty & Durable Structure

• Main frame welded with thick H‑beam steel, overall stress‑relief annealing
• Stable running, low vibration, low noise, long service life
• Precise gear or chain drive, high transmission efficiency, low maintenance
• Automatic centralized lubrication system to extend service life of key parts

 

4. Efficient & Energy‑Saving Production

• Forming speed: 10–25 m/min adjustable
• High output up to 6,000–8,000 m² per 8‑hour shift
• Hydraulic uncoiler, automatic stacker available as options
• Only one operator required, greatly reducing labor cost

 

5. Flexible & Customizable Design

• Supports common profiles: 840, 900, 1050, 760, 820 trapezoidal panels
• Customizable profile height, pitch and effective width according to customer drawings
• Suitable materials: PPGI, GI, galvalume, aluminum‑magnesium‑manganese, thin stainless steel
• Material thickness range: 0.3–1.2 mm
