What are the different types of coatings for a castor frame?

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

Polished

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  

​

Electrogalvanized

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.

 

•Thick coatings

• 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 Coated

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
