Is it environmentally friendly?

Yes, chrome-free options help reduce pollution.

What is the difference from zinc coating?

Zinc plating is an electro/thermal deposition process, while coating is a spray application.

Is it suitable for outdoor use?

Yes, it provides strong resistance to atmospheric corrosion.

Does it sacrifice itself for protection?

Yes, the zinc layer corrodes first to protect the base metal.

What is the thickness range of zinc plating?

5-150μm, depending on the process.

Processing Overview

Description: Zinc plating is an electroplating or hot-dip process that deposits a zinc layer on the substrate surface, typically 5-25μm thick (electroplating) or 50-150μm thick (hot-dip). The process includes pretreatment (pickling, activation), galvanizing, and post-treatment (passivation or oiling).

Applicable Materials: Steel, iron, zinc alloys, and copper substrates.

Visual Appearance: Silver-gray or bluish-white hues, matte or glossy finish, and rust-resistant appearance.

Advantage

Excellent Corrosion Resistance: The zinc layer sacrificially protects the substrate from atmospheric and aqueous corrosion, extending its service life by 10-20 years.
Eco-Efficient: Low cost, suitable for high-volume rust-proofing of parts such as bolts and brackets.
Good Adhesion: Bonds tightly to steel and resists impact and bending.
Moderate Conductivity: Suitable for electrical grounding and shielding applications.
Environmentally Friendly Options: Chromium-free passivation reduces hazardous materials and allows for easy recycling.
Multiple process options: Uniform electroplating and thick hot-dip coating, flexible to meet specific needs.

Precautions

Hydrogen embrittlement risk: Steel requires a low-hydrogen process and brittleness testing.
Thickness control: Select thickness based on the environment and test for uniformity.
Post-treatment: Passivation for white rust prevention and salt spray resistance testing.
Design considerations: Avoid deep holes that could affect the coating; plan drainage holes (for hot-dip coating).
Quality standards: Comply with ASTM B633 or ISO 2081, checking thickness and adhesion.
Safety measures: Dispose of acidic wastewater and comply with environmental regulations.
