Structural Steel Liquid Painting Line with Automated Material
Handling
Heavy-Duty Liquid Painting Solution for Structural Steel
Fabrication
This automated liquid painting line is developed for the surface
treatment of carbon steel structural components, delivering
reliable coating quality for heavy-duty industrial applications.
Designed to process medium and large fabricated parts, the system
combines efficient material handling with a flexible painting
process, making it suitable for industries such as construction
machinery, transportation equipment, steel structures, energy, and
general manufacturing.
Every production line is engineered according to the customer's
workpiece dimensions, production targets, paint specifications, and
plant layout to ensure maximum operating efficiency.
Complete Coating System
The production line integrates all major coating operations into a
continuous workflow, including:
Each process is coordinated through an automated material handling
system to minimize manual intervention while maintaining stable
production performance.
Immersion Painting Technology
The system adopts an inclined basket dipping process that allows
liquid coating material to reach all exposed surfaces of the
workpiece. This method is particularly effective for structural
steel components with welded joints, internal cavities, and
irregular geometries where conventional spray coating may provide
limited coverage.
Typical process parameters include:
Process Stage | Typical Parameters |
|---|
Immersion Painting | Approximately 6 minutes |
Paint Draining | Approximately 90 minutes |
Drying | 60–80°C for approximately 48 minutes |
Natural Cooling | Approximately 6 minutes |
Process settings can be adjusted to accommodate different coating
materials and production requirements.
Automated Material Handling
A Power & Free overhead conveyor system transports workpieces
efficiently throughout the production line while allowing
independent carrier movement and accumulation between processing
stations.
System capabilities include:
Maximum carrier capacity up to 2,000 kg
Adjustable conveyor speed from 0.5 to 3.0 m/min
Flexible accumulation and buffering
Forklift-assisted loading and unloading
Stable transportation for oversized structural components
The conveyor configuration improves production flexibility while
supporting continuous operation and future line expansion.
Production Advantages
The immersion coating process delivers complete paint coverage and
consistent film thickness, providing excellent protection against
corrosion, moisture, and harsh operating environments.
Combined with automated material handling and energy-efficient
drying equipment, the production line offers:
Uniform coating quality
Improved corrosion resistance
Higher production throughput
Reduced labor intensity
Optimized paint utilization
Lower operating costs
Stable and repeatable production performance
