Equipment protection
GRP Composite Trench Covers is used where utility, electrical and industrial equipment needs a durable housing or protective cover. GRP provides a practical material choice for external and operational environments, particularly where long-term corrosion resistance, weather exposure and a bespoke fit are important.
Every enclosure, cabinet, kiosk or cover starts with the equipment and its operating context. Captrad can work from dimensions, drawings and site information to discuss access arrangements, apertures, finishes and the practical details needed for installation and maintenance.
