Hot-Dip Galvanizing Treatment

Using high-quality steel as the base material, the tray is processed by hot-dip galvanizing. The tray is immersed into molten zinc to form a dense zinc-iron alloy coating.

Performance Features

Strong coating adhesion firmly bonded with the base metal, excellent rust resistance, weather resistance, and impact resistance. The zinc layer forms a stable oxide film in the air, effectively resisting moisture, salt spray, and industrial atmospheric corrosion.

Core Advantages

Long overall anti-corrosion service life, not prone to oxidation or rust, with a service life of more than 20 years. Even if partially damaged, the sacrificial anode protection of the zinc layer still prevents steel corrosion.

Applicable Scenarios

Outdoor open-air sites, factory outdoor pipeline areas, coastal areas with high salt spray, foreign trade export projects, and other harsh environments.

Electro-Galvanizing Treatment

Using steel base material, a uniform zinc layer is deposited on the surface through an electrolytic deposition process, forming a bright and smooth protective layer.

Performance Features

Smooth and bright surface with uniform color, providing basic rust protection. The coating is thin but dense, with good decorative appearance.

Core Advantages

High cost-effectiveness, economical cost, neat and beautiful appearance, suitable for large-scale standard wiring projects. Processing precision is easy to control, with good product dimensional consistency.

Applicable Scenarios

Indoor dry workshops, conventional wiring inside ordinary buildings, equipment rooms, dry environments with low anti-corrosion requirements.

Electrostatic Powder Spraying Treatment

The steel substrate surface is sprayed with fire-retardant plastic powder (epoxy resin or polyester powder) and cured at high temperature, forming a uniform and dense organic coating.

Performance Features
The coating has fire-retardant and flame-resistant characteristics, good insulation performance, a smooth surface that resists dust accumulation, strong dust and stain resistance, and can resist mild chemical corrosion. The coating can be customized in various colors.

Core Advantages
Uniform and attractive color, excellent aging resistance, not prone to fading after long-term use. The coating has good electrical insulation, effectively reducing electromagnetic interference on lines and improving signal transmission quality.

Applicable Scenarios
Building equipment rooms, fire protection engineering, office buildings, indoor weak current wiring in shopping malls, hospitals, schools, and other places with requirements for fire safety and aesthetics.

Product Structural Advantages

The solid bottom structure has a continuous bottom plate without holes, effectively preventing small animals from entering, blocking dust from falling, and protecting cables from external damage.
