Surface Treatment for Industrial Fasteners
Proper surface treatment ensures that metal parts are more resistant to external factors, such as corrosion, wear, or chemical exposure. In many industrial applications, surface treatment is therefore an important part of the production process.
Hetraco supplies specialty fasteners and fastening components for industries where reliability is paramount. This also includes ensuring proper protection of the material. That is why we collaborate with carefully selected partners who specialize in various surface treatments for metal parts. This allows us to manage the entire process: from production through to the desired coating or protective layer.
What is a surface treatment?
Surface treatment involves applying a coating to a metal part. This can serve various purposes, depending on the product’s application. For example, surface treatment can be used to protect the metal from corrosion or wear, extend the component’s service life, or improve adhesion for paint or adhesive.
It is a process used to alter specific material properties. In the case of metals, this is often achieved through a chemical treatment. This process forms a thin layer on the surface that protects the material or imparts additional properties.
Surface Treatments Through Regular Partners
Hetraco does not perform surface treatments in-house. For these processes, we work with trusted partners who specialize in industrial coatings and treatments. This collaboration allows us to arrange various treatments for the fasteners we manufacture. Commonly used treatments include:
- Chemical Blackening
- Electrogalvanizing
- Electrolytic Galvanizing
- Hot-dip galvanizing
- Geomet
- Passivation
- Nickel Plating
- Cash In
- PTFE Teflon Coating (Xylan)
- Hard Chrome Plating
- Zinc flake coating
- Sherardizing
- Nitriding
- Manganese Phosphate Treatment
These treatments are widely used for fasteners in industrial installations, machinery, and structures where protection and reliability are key. Is the treatment you’re looking for not listed here? We’d be happy to work with you to find a solution.
The Right Treatment for Every Application
The choice of a surface treatment depends heavily on the environment in which a component is used. In industries such as petrochemicals, offshore, energy, and heavy machinery manufacturing, fasteners may be exposed to moisture, salt, high temperatures, or chemical influences. In such situations, it is important that the coating or treatment is suited to the stress the component will endure and its expected service life.
That is why, at Hetraco, we assess factors such as material type, operating environment, and technical specifications in advance. Based on this, we can determine which surface treatments are suitable for the component in question. This ensures the product’s performance and helps prevent downtime or additional maintenance.
From Production to Surface Treatment
Many fastening components are first manufactured at Hetraco’s in-house machine shop. The component can then be given the desired surface treatment by one of our regular partners. This approach ensures that production, treatment, and delivery are well coordinated. For customers, this means they have a single point of contact for the entire process. This keeps the process straightforward and allows the treatment to be tailored to the application, the material, and the conditions under which the component will be used.
Advice on the Right Surface Treatment
Not every coating or treatment is suitable for every application. Factors such as load, environment, temperature, and material type all play a role here. Do you need a specific surface treatment, or are you looking for advice on the right protection for your fasteners? The specialists at Hetraco are happy to work with you to find a solution that fits your application.
