Structural Steel Liquid Painting Line with Automated Material Handling

Designed for Heavy Structural Components

This liquid painting production line is specifically engineered for carbon steel structural parts, providing reliable coating performance, high operational efficiency, and flexible process configuration. The system utilizes immersion coating technology and is suitable for medium and large fabricated steel components used in construction, transportation, industrial equipment, and heavy machinery manufacturing.

The production line can be customized according to workpiece dimensions, production capacity, coating specifications, and factory layout requirements.

Immersion Coating Process

The system adopts a 45° inclined basket dipping design, allowing the coating material to fully contact the workpiece surface and ensuring uniform paint coverage, even on complex welded structures.

Coating Features

• Full-surface immersion coating

• Excellent paint penetration

• Uniform film thickness

• Suitable for complex structural components

• Reliable corrosion protection

Material Handling System

The production line is equipped with a Power & Free overhead conveyor system that enables flexible workpiece transportation and process accumulation.

Handling Features

• Power & Free conveyor technology

• Independent carrier movement

• Process accumulation capability

• Forklift-assisted loading and unloading

• Stable handling of heavy workpieces
