Coatings

Physical Vapor Deposition (PVD)

Physical Vapor Deposition (PVD) is the process of combining metal vapor with gases and applying it to steel using a vacuum chamber. The process creates a micro thin, transparent, colored film on the stainless steel which increases the durability without adding to the weight of the panel. The process of creating the PVD coated panel is more environmentally friendly than other metal coating processes as it doesn’t create pollutants or waste. The PVD film is resistant to wear, UV and corrosion without needing a clear topcoat. Coated panels can be formed at a 90° angle without damage to the PVD finish 

Clear Lacquer Coatings

Many decorated metal manufacturers will use a specific type of coating adapted to their specific products and their intended usage. In architectural applications, most decorated plain sheet metals in Copper and Aluminum are coated with a nitrocellulosic type lacquer. Whereas other metals and metal laminates use epoxy or urethane coatings.

Transparent Color

With this process a base metal can be covered by a thin layer of any transparent PVD color. The underlying decorative finish is visible through the transparent color, creating spectacular decorative finishes.

Metal Colors, Tolerances, Variances

Any metal surface may show very slight variances in the color of the alloy, from sheet to sheet.
These variances have their origin in production methods and batch mode production in the steel mills. Highly structured design patterns or rough type textures are often the best way to overcome such variances. A specifier should establish some parameters of acceptable tolerances when this is important.

PVC Mask

Most decorated sheet metal is shipped with a removable PVC protective mask. The mask is to protect the sheet during handling, transport, and fabrication. Any premature removal of the mask may expose the metal to possible damage during fabrication and installation.
