For many years, stainless steel has been the material of choice when it comes to sensitive equipment housings in harsh environments, but GRP, or glass reinforced polyester, has become a serious alternative, since it is more cost-effective and it weighs a lot less. Apart from those two aspects, GRP is also more than strong enough to replace stainless steel. These qualities make GRP an excellent choice for numerous products for harsh environments. One of the top manufacturers of these products is MEDC. MEDC has over 30 years of experience in researching and producing GRP. Within their product range they supply warning beacons, sounders and loud speakers… All of them suited for use in harsh environmental settings. GRP products of MEDC are:Light: A GRP housing matches its weight with aluminium housings, but weighs much less than stainless steel.Strong: GRP has been tested the same way as metal housings, testing its impact, vibration, shock and explosion proof resistance.Corrosion free: You could easily say that GRP is impermeable while using it outdoors, no matter what the weather conditions are.Low cost: Producing metal housings demands many mechanical actions, while producing GRP only demands one mechanical action.Low maintenance: Metal housings must be corrosion-inspected periodically; not necessary when GRP is used.UV stable: Many tests and long term experience have proven that GRP is maintenance free for more than 20 years. Intensive independent tests, conducted by BASEEFA, show that GRP is suited for using with Ex and Non-Ex certified products. Non-flammable: Also tested and determined by BASEEFA: GRP has non-flammable characteristics and is therefore suitable for use in settings with a fire risk.Resistant to chemicals: GRP is resistant to most known thinned acids, chemicals, H2S and CO2. With high acid concentrations and strong alkaline, GRP is less susceptible to erosion than metals.Ingress Protected: compliant to IP66 & IP67 |
