DD Fasteners Introduces Advanced Ruspert Coating Technology – The Ultimate Anti-Corrosion Solution for Fasteners

What is Ruspert Coating?
Ruspert coating, also known as ceramic coating, is a high-performance surface treatment consisting of a three-layer protection system:

🔹 First Layer: Metallic Zinc Coating – Forms the base protective layer, enhancing the fastener’s structural integrity.
🔹 Second Layer: Special Chemical Conversion Film – Provides additional protection, improving adhesion and resistance to oxidation.
🔹 Third Layer: Anti-Rust Ceramic Surface Coating – A baked ceramic topcoat that reinforces weather resistance and aesthetic appeal.

Unrivaled Benefits of Ruspert Coating
✅ Exceptional Corrosion Resistance

Withstands 500 to 1,500 hours in salt spray tests (ASTM B117 standard).
Suitable for high-humidity, high-salt, and chemically treated environments.
Ideal for coastal, industrial, and outdoor construction projects.
✅ Superior Compatibility with Treated Wood

Prevents corrosion when used with pressure-treated timber and chemically treated wood, making it the preferred choice for decking, fencing, and outdoor structures.



✅ Contact Corrosion Resistance

Eliminates the risk of contact corrosion when used alongside other metals or coated materials, even in wet and dry conditions.
✅ Low-Temperature Baking Technology

Coated at temperatures below 200°C, preventing tempering issues, hardness reduction, or structural weakening in fasteners.
✅ Customizable Color Options

Available in a variety of colors to match project aesthetics.
Ensures seamless integration with different construction materials.
✅ Enhanced Surface Finish & Adhesion

Stronger adhesion compared to traditional Dacromet coatings.
Provides a smooth, visually appealing finish while ensuring long-term durability.
Versatile Applications for Ruspert-Coated Fasteners
Ruspert-coated fasteners are engineered to excel in high-corrosion environments, making them ideal for:
✔ Roofing & Cladding Installations – Withstands extreme weather conditions.
✔ Marine & Coastal Structures – Provides superior saltwater resistance.
✔ Steel & Metal Constructions – Prevents contact corrosion.
✔ Outdoor & Industrial Projects – Ensures long-term performance and reliability.
