Semi Trailer – Product Overview

Manufacturing Process

ZW Group follows strict ISO 9001-certified production workflows to ensure product consistency and reliability. Each trailer undergoes a multi-stage fabrication process:

1. Steel Cutting & Frame Assembly: Precision laser/plasma cutting for accurate component shaping.

2. Automatic Submerged Arc Welding (SAW): Guarantees deep weld penetration and structural uniformity.

3. Shot Blasting & Surface Prep: Cleans metal surfaces to SA 2.5 grade, removing all impurities.

4. Painting & Drying: Three-layer anti-corrosion coating baked in controlled-temperature booths.

5. Axle Installation & Electrical Wiring: Professionally mounted under strict torque specifications.

6. Quality Control Inspection: Dimensional checks, weld integrity, and electrical system tests.

7. Road Simulation Testing: Simulated vibration and stress test for real-world durability validation.

Load Capacity & Stress Testing

Our 4 axle flatbed trailers are rated for up to 80 tons payload depending on road regulations and tire/axle configurations. Prior to dispatch, each trailer undergoes:

• Hydraulic pressure tests

• Axle alignment verification

• Twist lock tension stress checks

• Ramp loading test with actual 40ft containers

These tests simulate the real-world conditions encountered on highways, docks, and rural terrain to guarantee performance even in harsh logistics environments.
