Various industries, including automotive and aerospace, heavily utilize sheet metal for part and component production. In the manufacturing process, sheet metal finishing emerges as a pivotal step, offering a spectrum of options, each distinguished by unique advantages and properties. A comprehensive understanding of these finishes empowers informed decisions for optimal selection in your upcoming projects.

Raw or Rough Finish:

The absence of any applied finishing treatment characterizes this sheet metal surface finish. Referred to as a raw finish, or at times, a rough finish, it is commonly employed when the base material inherently suits the intended usage environment.

Stainless steel sheet metals, for instance, may adopt a raw finish when utilized outdoors due to their corrosion-resistant nature, eliminating the need for additional polishing.

Applications of raw finishing encompass diverse sectors such as pharmaceutical and chemical plants, jewelry manufacturing, air conditioning systems, and automotive design.


Electroplating, also referred to as electrodeposition, is a sheet metal finishing method that entails applying a layer of another metal (substrate metal) onto the surface of the sheet metal. Typically, the substrate metal, which is often lighter or more cost-effective, is encapsulated within a thin metal shell. This finishing technique is commonly utilized in the production of items such as gold-plated watches, silver-plated teapots, and chrome-electroplated faucets.

Electroless Plating

Electroless plating, also referred to as auto-catalytic or chemical plating, is a non-electric method of depositing metal onto sheet metal surfaces. This process involves the chemical deposition of metals in a reducing bath, facilitating a catalytic reduction of metal ions to plate the part. Key advantages of electroless plating include:


  – Uniform Layer Formation

  – Flexibility in Thickness and Volume

  – Options for Bright, Semi-Bright, and Matte Finishes


This technique finds application in various industries, serving purposes such as brake pistons, pump housings, pipe fittings, injection molds, dies, food molds, and more.


Anodizing is a surface finish process for sheet metal that enhances corrosion resistance through an electrochemical procedure. This method transforms the sheet metal surface into a thin yet exceptionally durable oxide layer.

Anodized components find applications in various sectors, including interior and exterior building finishes, bathrooms, doors, windows, and roofs.
