Surface treatment

Surface treatment

Surface treatment is a critical part of the fastener manufacturing process because it can affect the performance, durability and aesthetics of the final product. From electrogalvanizing to powder coating and hot-dip galvanizing. At Hofa, we can help you choose the right surface treatment. Below we have explained some of the options.

P1000

P1000 is a surface treatment for screws used to protect them from corrosion and wear. This treatment consists of a thin layer of zinc phosphate applied to the surface of the screws by a chemical process. The zinc phosphate layer provides excellent adhesion for further paint or coating systems and significantly increases the corrosion resistance of the screws. This is especially important for screws exposed to moist or corrosive environments.

P1000 surface treatment also provides increased resistance to abrasion, extending the life of the screws. The treatment also improves the appearance of the screws by giving them a smooth and uniform surface. Overall, P1000 is an excellent choice for screws used in applications where corrosion and wear may be a problem. Due to the protective effect of the treatment, the screws last longer and maintain their appearance.

Sealinox

Sealinox is a surface treatment often applied to screws and other fasteners. The process involves applying a thin layer of a special coating to the surface of the screw, making it more resistant to corrosion and wear. The Sealinox coating consists of a combination of different materials, including chromium, nickel and molybdenum. These materials provide excellent corrosion resistance, even in aggressive environments such as salt water or acidic solutions. In addition, the coating helps to reduce friction between the screw and the material in which it is fastened, reducing the likelihood of wear and damage.

The benefits of Sealinox treatment for screws are numerous. In addition to improved corrosion and wear resistance, the coating can also extend the life of the propeller and improve performance. Screws treated with Sealinox are therefore an excellent choice for applications where durability and reliability are essential, such as in the shipbuilding, offshore and chemical industries.

Zinktop

Zinc doping is a surface treatment often used for screws and other metal parts to protect them from corrosion. The process of zinc plating involves dipping the screws into a bath of molten zinc, which deposits a layer of zinc on the surface of the screws. This layer of zinc protects the screws from corrosion because the zinc acts as a barrier between the metal of the screw and the environment. The zinc will oxidize instead of the metal when exposed to the elements, making the screws last longer.

Zinc plating is also an economically viable solution for protecting screws. It is a relatively inexpensive way to prevent corrosion and extend the life of metal parts. In addition, the process of zinc plating is relatively quick and can be applied to a wide range of screws and other metal parts. In short, zinc plating is an effective and economical way to extend the life of screws and protect them from corrosion.

Silver ruspert

Silver Ruspert is a surface treatment commonly used for screws and other fasteners. The process involves applying a thin layer of silver to the surface of the screw, followed by a coating of organic polymer layers to protect the surface from corrosion and wear. The Silver Ruspert treatment is designed to extend the life of screws and other fasteners and make them resistant to the effects of moisture, chemicals and temperature fluctuations. The coating also provides excellent adhesion and reduces the likelihood of corrosion between different metals.

This surface treatment is often used in the building and construction industry, where screws are exposed to the elements and other challenging conditions. The use of Silver Ruspert-treated screws can contribute to the overall durability and safety of construction projects and other applications. In short, Silver Ruspert treatment provides excellent protection against corrosion and wear and prolongs the life of screws and other fasteners.
