Invisible manhole cover made from reinforced resin — rustproof, wearresistant, and designed for stable, safe, and discreet drainage access. Key benefits Safety and appearance: Concealed cover design hides the manhole opening and reduces exposure to impact from children or objects, keeping outdoor and indoor areas both safer and more attractive. Durable and low maintenance: Reinforced resin resists rust and wear, minimizing corrosion and longterm upkeep compared with metal covers. Stable under load: Detachable base creates an even support surface and prevents damage caused by uneven pressure. For higher loads, the structure can be reinforced with cement to increase strength, offering a practical alternative to heavy metal inspection covers. Easy inspection and service: Lift points around the cover accept hooks for quick removal, simplifying cleaning, inspection, and maintenance. Key features Material: Reinforced resin — rustproof and wearresistant. Mounting: Detachable base for improved stability and even pressure distribution. Load capacity: Resilient structure; can be further reinforced with cement to meet heavier load requirements. Design and function: Concealed/invisible finish for improved aesthetics; suitable as square drainage covers, recessed drainage covers, large flat slabs, or removable recessed covers for indoor or outdoor use. Maintenancefriendly: Premade holes for hook lifting make removal and replacement simple and safe. Compatibility and performance Intended for outdoor environments but suitable for indoor use where a lowprofile or recessed cover is needed. Functions as a practical replacement for traditional metal inspection covers, combining corrosion resistance with the option to boost loadbearing capacity with cement reinforcement. Designed to perform reliably in residential areas, courtyards, gardens, and schools. Typical applications Residential driveway or backyard drainage: a lowprofile, rustproof cover that blends with landscaping while allowing occasional heavy loads after reinforcement. Courtyards and pathways: concealed recessed slabs that maintain aesthetics and provide safe walking surfaces. Schools and playground perimeters: durable, impactresistant covers that reduce safety risks and simplify maintenance. Installation and maintenance tips Place the detachable base on a level substrate to ensure even load distribution. For higher traffic or vehicle loads, add cement reinforcement around or beneath the resin structure to increase bearing capacity. Use a hook at the preformed lift points to remove the cover for inspection or cleaning; securely after maintenance. Materials and function are consistent with the original design: reinforced resin construction, detachable base, concealing design, cementreinforcement option for loadbearing, multifunctional square/recessed cover use, and hookfriendly lift holes for easy maintenance.
