• Material: The PVC manhole cover with a key is constructed using polyvinyl chloride (PVC), a synthetic thermoplastic known for its durability, strength, and resistance to corrosion. PVC is chosen for its excellent properties that make it suitable for underground applications.
• Reinforcement: To ensure strength and stability, the PVC manhole cover with a key is reinforced with ribs or grids on the underside. These reinforcements prevent flexing or bending under heavy loads, ensuring the cover can support the weight placed upon it.
• Locking Mechanism: The key feature of this type of manhole cover is its locking mechanism. The locking system is integrated into either the cover itself or the frame surrounding it. It requires a specific key, designed to match the lock s configuration, to open and close the cover. The key is unique to the particular locking system and is held only by authorized personnel.
• Shape and Surface Design: The cover is typically designed in square shape, depending on the specific requirements. It features a patterned surface that provides enhanced traction, reducing the risk of slips and falls, especially in wet conditions. The pattern also adds structural integrity to the cover.
