The performance of an enclosure (either metallic or plastic) during its service life will be influenced by environmental conditions. Selecting the correct material for the application will ensure a long hassle-free installation.
Extreme conditions such as continuous direct exposure to sunlight, extreme temperatures and aggressive weather elements like wind-blown sand eventually, impact on the enclosure's life. Steel enclosures likely have corrosion when exposed to moisture and chemicals, the unprotected finish surfaces of Fiberglass enclosures can be adversely unprotected finish affected by direct exposure to sunlight (a condition known as fiber bloom).
On the other hand, PVC enclosures provide an excellent balance between material strength and environmental performance. The surface the appearance of VSM Plast make PVC enclosure boxes are not adversely affected by exposure to UV (so no fibre bloom!), that adds years of weather standing & exposure particularly well suited for marine areas and salt water spray.
As FRP enclosures are made with a combination of fine glass fibers with plastic and resin, there are minor but important issues that can arise in some environments such as waterparks, marine and other outdoor applications known as fiber bloom/ blooming. Fiber bloom is where the constant exposure to UV rays of the sun weakens the fibrous qualities of the FRP material and exposes internal fibers. In normal circumstances, blooming only affects aesthetically and makes the surface slightly difficult to work. However, in some situations, the non-conductive nature of FRP can be compromised and pose an electrical shock risk for workers alike.
It is possible to lessen the degeneration of FRP enclosures with constant outdoor exposure by simply keeping it clean. That's it! You only need to care for FRP grating & other structural elements. The cleaning of your FRP enclosures surface not only make them look good but also removes grease, abrasives, oil and any chemicals spilled on the surface which can chemically change the undesirable surface properties. This reduces slip hazards, helps prevent the surface from weathering, and helps the FRP structure to retain the non-conductive nature what it known for.
