Coating Options

At Rapid, we offer a comprehensive range of coating options designed to enhance the durability, corrosion resistance, and aesthetic appeal of our fasteners. Our extensive selection of coatings includes:

Black Oxide – providing a sleek black finish while offering a degree of corrosion resistance. Black oxide coatings are often used for aesthetic purposes, as well as to reduce glare and improve the overall appearance of the fasteners. This option is particularly popular in applications where a low-profile, matte finish is desired.

Chemical Black – similar to black oxide, chemical black coatings are created through a chemical process that offers a deep, uniform black finish. This method provides enhanced corrosion resistance and is suitable for various applications, including those requiring non-reflective surfaces.

Electro Zinc Plating – available in clear, yellow, and black finishes, electro zinc plating involves applying a thin layer of zinc to the fasteners through an electroplating process. This coating provides excellent corrosion protection while maintaining the fasteners functionality. The different finishes can be chosen based on aesthetic preferences and specific environmental conditions.

Iso Fit Galvanise – is a specialised process that ensures a high level of corrosion resistance through a zinc coating. This method is particularly effective for fasteners used in harsh environments, as it offers superior protection against rust and degradation.

Hot Dip Galvanise – this traditional method involves dipping the fasteners in molten zinc, resulting in a thick and durable coating that offers outstanding corrosion resistance. Hot dip galvanisation is ideal for outdoor applications and environments where fasteners are exposed to moisture and corrosive elements.

Nickel Coating – are known for their excellent corrosion resistance, wear resistance, and aesthetic appeal. This option is suitable for fasteners that require both functional and decorative properties, making them a versatile choice for a wide range of applications.

Phosphate – provides a non-metallic surface treatment that improves corrosion resistance and enhances adhesion for subsequent coatings, such as paints and lubricants. This option is particularly useful in applications requiring additional surface protection.

PTFE / Xylan – these advanced coatings offer low friction properties and excellent chemical resistance. PTFE (Polytetrafluoroethylene) and Xylan coatings are ideal for applications that demand smooth operation and reduced wear, making them suitable for use in harsh chemical environments.

Sherardising – this process involves coating the fasteners with zinc through a vapor phase method, resulting in a smooth, uniform finish that provides excellent corrosion resistance. Sherardising is particularly effective for intricate shapes and small components.

Zinc Flake Coatings (including Dacromet, Delta, and Geomet) – are highly effective in providing corrosion protection while being environmentally friendly. These coatings are known for their excellent abrasion resistance and can be applied in various thicknesses. Dacromet, Delta, and Geomet are specific brands of zinc flake coatings that offer unique properties, including enhanced adhesion, flexibility, and resistance to harsh chemicals and temperatures.

Zinc Nickel – this coating combines the benefits of zinc and nickel, providing superior corrosion resistance and wear properties. Zinc nickel coatings are particularly effective in automotive and aerospace applications, where high performance and durability are essential.

Each of these coating options are designed to meet specific performance requirements and environmental conditions, ensuring that our fasteners provide long-lasting durability and reliability.

We are committed to offering our customers the best possible solutions for their fastener needs, allowing them to choose the coating that best suits their applications and enhances the overall performance of their products.
