Surface Finishing
At Epko Metal, we simplify the process of obtaining sheet metal parts with the surface finishing options that meet your specific needs. Our platform offers a wide range of standard metal surface treatments, available in various colors and finishes, ensuring mass production quality at competitive pricing.
Powder coating is a dry finishing process that delivers a durable, high-quality finish, improving both the appearance and longevity of your parts. With a wide range of colors and textures, including both glossy and matte finishes, powder coating is a popular choice for both protective and decorative applications. Technological advancements in powder coating have resulted in superior performance, making it an ideal choice for various materials, including powder-coated steel.
E-coating involves immersing the part in a pool of liquid paint, which is then electrified. The electric current determines the coating thickness, allowing for precise control and uniform film layers. This method is particularly beneficial for high-precision parts, as the thin and even coating maintains tight tolerances while providing excellent protection.
Zinc plating is a widely used method for protecting metals like iron and steel from corrosion. By applying a thin layer of zinc to the surface, this process acts as a physical barrier, preventing rust from reaching the underlying metal. Zinc plating is commonly used for screws, fasteners, and other small parts that will be exposed to corrosive environments.
Anodizing is an electrochemical process that converts the surface of aluminum into aluminum-oxide, creating a coating that is hard, inert, and electrically insulating. This process allows for vibrant color options to be added to aluminum parts, with the anodized layer providing excellent adhesion and durability.
Passivation is a treatment applied to stainless steel to restore its corrosion-resistant oxide layer after machining or other processes. This natural protective layer adheres securely to the metal, preventing corrosion and extending the life of the part.
Galvanization is a rust-prevention technique in which a layer of zinc is applied to steel, creating a barrier that protects against corrosion. Galvanized metal is known for its increased strength and durability, making it an ideal choice for parts exposed to harsh environments.
