Polyester enclosures made of glass fibre reinforced plastic (GRP) combine low weight with high mechanical strength. They are impact-resistant, corrosion-free and ideal for use in demanding industrial environments. Thanks to their high degree of protection (IP66/IP67) and optional conformity to UL94 V0, EN 45545 or ATEX standards, they reliably fulfil all common requirements - whether in mechanical engineering, railway technology or hazardous areas.
Thanks to various designs and individual processing options, polyester enclosures offer maximum flexibility for series solutions and customised applications.
Technical highlights at a glance:
Our polyester enclosures are available in several versions - tailored to the respective requirements of your application. Whether classic use in mechanical engineering, certified solutions for railway technology or standard-compliant versions for potentially explosive atmospheres: All models are based on glass fibre-reinforced plastic, are impact-resistant, weatherproof and offer reliable protection to IP66.
Choose from four enclosure types - each with a clearly defined area of application and technical strength:
Our polyester enclosures can be processed in a variety of ways and customised to your application - for example by milling, drilling or integrating pre-assembled components. EMC coatings and special colours are also possible.
In this way, a standard enclosure can be turned into a solution that precisely matches your application in no time at all.
