Oftentimes we don’t realize how much work is put into creating a customized piece of sheet metal. There are numerous steps that need to be taken in order to achieve perfection, but the metal finishing process is probably one of the most important steps when it comes to improving the aesthetics of a sheet metal project.
At R.R. LeDuc Corporation, our Western Massachusetts-based company provides customers with in-house powder coating and has an extensive network of NADCAP certified vendors for all other metal finishing needs. Below are a few of the most common forms of metal finishing procedures.
Types of Surface Metal Finishing
- Sand Blasting. This is the most common type of metal finishing available for stainless steel, aluminum and copper. The sheet metal is exposed to a powerful yet precise jet of fine sand to create a corrosion-resistant surface. After sand blasting, other finishes can be applied.
- Metal Plating. Another common metal finishing technique, metal plating is the process of covering a metal product with a substrate of another metal. Nickel, silver, gold, zinc and other “soft metals” are used to coat harder metals. The idea is to make the product more resistant to environmental factors as well as improve aesthetics.
- Brushed Metal. Normally used to remove imperfections on the surface of metal products, brushing the surface with abrasive bristles can often restore metal to it’s original functionality. For example, brushed metal can restore gears or other moving mechanical parts. The technique is also used to create a scratched, textured surface.
- Metal Polishing. Mostly used on stainless steel, copper or aluminum, metal polishing is what gives each product it’s shine and shoot surface. At R.R. LeDuc Corporation, we will often polish our sheet metal products in order to prepare them for metal plating. The result? A glossy, gorgeous finish.
- Powder Coating. As R.R. LeDuc Corporation’s specialty, powder coating serves two purposes: aesthetics and functionality. The powder can be customized to any color, and in turn the product also serves to protect the underlying metal beneath. Although the color may not be as vibrant as regular paint, the coating will stay on much longer and protect the finished product from corrosion.
