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.

Rebar Installations

Rapid Industrial Fasteners as Premier distributors for the Fischer FIS EM resin system, used with the Fischer FRA Rebar anchor, opens entirely new opportunities for structural engineers.

Often, existing buildings are extended or rebuilt. This means in practice that the reinforcement of old and new sections of buildings must be connected. Holes to a depth up to two meters can now be drilled for post-installed rebar.

Rapid now offers two special systems which make the installation of post installed rebar a straightforward process; the original fischer Injection Mortar System FIS V, a high-performance vinyl ester hybrid mortar and the latest combination of Injection Mortar System FIS EM, epoxy mortar with rebar anchor FRA.

The systems have European Technical Approval (ETA) and General Construction Approval by the ‘Deutsches Institut für Bautechnik (DIBt). Based on best performance epoxy resin mortar the FIS EM is suitable for rebars up to Ø 40 mm and the FRA anchor.

The rebar anchor system has been designed especially for extreme tension loads, e.g. at a column base, which can’t be transmitted to the concrete element by conventional anchors. The system is composed of a rebar connected to a stainless steel threaded rod by friction welding which makes it suitable for outdoor use and allows extremely high tensile loads.
