Cable trays are one of the commonly used cable management systems that use steel or aluminium as the substrate.  Since most of the major industries are situated in highly corrosive environments (close to the sea, industries, etc.), the cable trays are susceptible to corrosion problems.  To prevent failure due to corrosion attack and extend the service life of the structure, S3C has designed and applied various types of coatings that provide protection to the cable trays.
