White zinc Plated Bolts

The commonly used white zinc-plated bolts are manufactured using zinc electroplating technology. This process is instrumental in protecting the surface of the bolts by applying a thin layer of zinc through a passive electrolytic deposition method, resulting in a white-greenish color on the metal surface.

    White zinc Plated Bolts are manufactured using zinc electroplating technology. This process is instrumental in protecting the surface of the bolts by applying a thin layer of zinc through a passive electrolytic deposition method, resulting in a white-greenish color on the metal surface. The zinc coating is resilient, preventing peeling, and forms a durable protective layer. This coating provides effective protection, giving the bolts a shiny white appearance, meeting high aesthetic requirements, and contributing to the prolonged lifespan of the bolts. White zinc-plated bolts find applications in the installation of workshops, steel frame structures, connecting pipes, and flanges. Additionally, these products are utilized in the centrifugal concrete industry, structural engineering, and machine assembly.

    The characteristic of White zinc Plated Bolts 

    - White zinc Plated Bolts: with durability grades 4.5, 5.6, and 6.6, with durable loads of 400 kgf/cmf, 500 kgf/cm2, and 600 kgf/cm2 respectively, commonly used for constructions in industries that do not require high durability and low load, chiller piping systems, MEP systems, and so on, where the design engineer calculates the durability level based on the product's mechanical properties.

    - White zinc Plated Bolts are used with zinc plating technology to protect the surface by coating a thin layer of zinc with a passivation that gives the metal surface a greenish-white color. This zinc coating will not peel off like paint, forming a reasonably good protective layer and providing a glossy white surface for bolts to meet the requirements of improving aesthetics and longevity.

    - The product's mechanical properties are expressed using two parameters: breaking strength and yield strength. Bolt marking number 5.6 is understood to be:

    • Tensile strength (minimum breaking strength): 500 Mpa

    • Yield strength (minimum yield strength): 300 Mpa

    Knowing and assessing bolt strength enables us to select the appropriate bolt for each connection application.

    Refer to the ISO 898-1 bolt mechanical characteristics table for more information.
