A Ruspert-coated fastener is a type of fastener that has been treated with a specialized corrosion-resistant coating called Ruspert, which is typically a zinc and aluminum alloy-based layer. The coating is applied to fasteners (like screws, bolts, or nails) used in applications where resistance to corrosion and environmental stress is critical, such as in metal roofing and other outdoor or industrial settings.
How does the Ruspert coating work?
The Ruspert coating is a multi-layered protective finish, typically comprising:
Zinc – for corrosion resistance.
Aluminum – for added protection and durability.
Special top layer – which helps to seal and further enhance the resistance to rust, oxidation, and other environmental factors.
This combination of materials creates a protective barrier that prevents the fastener from corroding when exposed to moisture, salt, or harsh weather conditions. The fasteners are commonly used in metal roofing systems, steel structures, marine applications, and other environments where the fastener is exposed to harsh elements.
