The Benefits of GRP Enclosures - Ensuring Protection For Your Components

To keep everything running smoothly, it’s important that your electrical components are kept safe from the harsh surroundings of an industrial environment. Heat and corrosion are just two of the effects that can cause a problem, and with plenty of other risk factors, it’s important to keep components covered by an enclosure.

BRES range of GRP enclosures from Uriarte Safybox

There’s a wide range of enclosures available to meet different needs, from those made of metal or plastic, to the more high-end GRP types. GRP stands for glass-reinforced plastic, which has become one of the most reliable types of enclosure material in terms of safety and longevity.

Choosing a GRP Enclosure is important, as it will help you to keep your components fully functioning, saving over time money and increasing efficiency. Although usually slightly cheaper options, plastic enclosures can expand and shrink depending on the temperature, and melts easily in a fire, while a metal enclosure can easily corrode, and conducts electricity. A GRP enclosure is highly resistant to extreme temperatures, is self-extinguishing, and non-corrosive.
