The type of finish has a huge impact of how long and durable your frame would be in the long run. So the finish you choose must take into account the environment & application it will be around whether its polished, electrogalvanized, Cathodic Electrodeposition (CED) processed, hot dip galvanized or powder coated
By rubbing it or by applying a chemical treatment, leaving a clean surface with a good reflection.
• Least amount of protection
• Most economical option of finish
A process in which a layer of zinc is bonded to steel using a chemical reaction to protect against corrosion.
Prone to scratches - when Scratched, the exposed steel corrodes and forms a rust "bubble“ can expand and lift the paint off the surface, creating a blister
Hot Dip Galvanized
Same chemical reaction as electrogalvanized, except the body is submerged in a bath of molten z inc during the process, covering more area.
• Corrosion resistant with sacrificial protection of zinc coating.
• Can be used outdoors in all weather conditions (like in construction industry).
• Smoother finish
Cathodic Electrodeposition (CED)
The frame is immersed in a bath that may consist of paint or epoxy water-based solution. An electric current is then used to attract the particles that are suspended in the liquid solution & deposit them onto the surface of the substrate.
• Covers hard-to-reach areas
• Most e-coats are not UV stable
• Gives precise control over the coating’s thickness, resulting in ultra-thin finishes that are difficult to achieve with powder coating
Powder coating involves the application of a dry powder consisting of a precise combination of epoxy resins & various curing agents. A spray gun is used to electrostatically apply the particles onto the surface of the substrate.
• Protect your products from wear, weathering, and UV exposure.
• More durabe finish than CED.
• Can be done on other coatings
