Mach’s GRP trench covers are available in solid top GRP trench covers and open mesh GRP trench covers. They are designed to cover holes or trenches during construction so that pedestrians and light vehicles in the excavation area around the site can pass safely while protecting the underlying pipes.
Solid top GRP trench covers are usually eye-catching yellow with a non-slip surface that maximizes visibility and minimizes the risk of slipping or falling in low light conditions or poor weather conditions.
