5 common metal surface finishes often used for unique applications
Mirror Finish
Mirror finish is created by mechanically treating the surface with a series of progressively finer abrasives. Alternatively a special rolling procedure is used which can simulate the appearance of mechanical abrasion. For this stage, it is essential to remove deep scratches as any surface defects will be very noticeable on the finished product. The final process involves buffing the surface for 5-10 minutes to create a mirror-like, highly reflective finish.
PVD Color
PVD is the abbreviation of Physical Vapor Deposition. It is a process carried out in high vacuum at temperatures between 150 and 500 .PVD stands for Physical Vapor Deposition, which refers to under the condition of vacuum, use Physical method to make material preparation technology of thin film deposited on the plated , A range of colors are available, including gold, black, bronze, blue and so on.
Embossed Finish
Stainless steel embossed sheet, also known as "3D stainless steel sheet", is a new concept sheet, which has strong three-dimensional effect. It is processed by embossing stainless steel sheets with machinery so that concave-convex patterns are made (dozens of patterns available).
Brushed Finish
Brushed metal is with a unidirectional satin finish. It is produced by polishing the metal with a 120–180 grit belt or wheel then softening with an 80–120 grit greaseless compound or a medium non-woven abrasive belt or pad. Brushing gives metal a distinctive look, as it retains some but not all of its metallic luster and is given a pattern of very fine lines parallel to the brushing direction.
Etched Finish
The coloring of stainless steel can be achieved by chemical surface treatment which actually modifies the surface oxide film on the metal. The colored finish is attractive but susceptible to finger-marks, which results in a color change and is not hard-wearing, and this should be considered when deciding on the use. The process uses acidic solution which, due to the variances in composition of the stainless steel and the process variables, can be guaranteed to be the same every time.
Sandblasted Finish
A sandblasting setup usually consists of three different parts: the abrasive itself, an air compressor, and a blaster nozzle. For etching and small object cleaning, a workstation to hold the piece of glass is also needed, as is some sort of collector to gather up excess dust.
