Surface Finishing & Coating
Depending on our customers application requirement or wish, our fasteners can also be provided with various surface finishes or coatings. For this service we cooperate closely with our longterm partnerships that are invididually specialized on different surface finishes and coatings.
GALVANIZATION
AT JTE , we offer high-quality galvanization services to enhance the durability and corrosion resistance of fasteners. Galvanization involves applying a protective zinc coating to steel or iron fasteners, creating a barrier that protects against rust, environmental damage, and mechanical wear.
Our galvanization process ensures:
- Long-lasting corrosion resistance
- Strong adhesion of the zinc layer
- Enhanced performance in outdoor and industrial environments
- Compliance with international coating standards
We specialize in:
Hot-Dip Galvanizing (HDG): Ideal for heavy-duty and outdoor applications.
Electro-Galvanizing: Best suited for applications requiring a smooth and uniform finish.
Thick-Film Passivation
Our Thick-Film Passivation Service is designed to provide fasteners with an advanced level of corrosion protection and improved surface finish. This process involves applying a thicker, protective conversion coating—typically over zinc-plated surfaces—to enhance their resistance to white rust, chemical exposure, and environmental wear.
Key Benefits:
Superior Corrosion Resistance: Extends the life of fasteners, especially in high-moisture or corrosive environments.Improved Aesthetic Finish: Offers a clean, uniform appearance with enhanced surface durability.Increased Salt Spray Life: Ideal for industrial applications demanding longer protection cycles.Eco-Friendly Options: Available with trivalent chromium-based formulations to meet RoHS compliance.
Zinc Flake
Zinc Flake Coating Service for Fasteners
Our Zinc Flake Coating Service offers a high-performance, non-electrolytic corrosion protection system for fasteners and components. Unlike traditional zinc plating, zinc flake coating is applied through dip-spin or spray methods, creating a dry, thin-film layer of zinc and aluminum flakes bonded with an inorganic matrix.
This coating provides exceptional corrosion resistance without the risk of hydrogen embrittlement, making it ideal for high-strength fasteners used in critical automotive, construction, wind energy, and marine applications.
Key Benefits:
Outstanding Corrosion Resistance: Exceeds 1000+ hours of salt spray performance (ASTM B117).
No Hydrogen Embrittlement: Safe for high-tensile fasteners (Class 10.9 and above).
Thin but Durable Coating: Maintains precise thread fit and dimensional accuracy.
Chemical and Temperature Resistant: Performs well in harsh chemical and high-temperature environments.
Environmentally Friendly: Chromium-free (Cr⁶⁺ free), RoHS and REACH compliant.
PTFE Coating
PTFE Coating Service for Fasteners
Our PTFE (Polytetrafluoroethylene) Coating Service provides fasteners with a high-performance, low-friction, and corrosion-resistant finish. PTFE is a non-stick fluoropolymer coating that offers excellent chemical resistance and thermal stability, making it ideal for use in aggressive environments such as chemical processing, offshore, automotive, and food-grade industries.
This coating forms a uniform, thin layer that reduces friction and prevents seizing or galling, even under extreme pressure and temperature conditions.
Key Benefits:
Exceptional Corrosion Resistance: Protects against moisture, chemicals, salt spray, and corrosive agents.
Low Coefficient of Friction: Provides excellent anti-galling and non-stick properties.
High Temperature Tolerance: Performs reliably in a wide temperature range (-200°C to +260°C).
Chemical and UV Resistant: Withstands acids, bases, solvents, and outdoor conditions.
Color-Coded Options: Available in various colors for identification and aesthetic purposes.
