Jiangsu Aozheng Metal Products Co., Ltd. is a professional Stainless Steel Manhole Cover manufacturer and supplier based in China. With a 32,000 m² factory and an annual capacity of 8,000 tons, we produce durable, corrosion-resistant covers for municipal, industrial, and architectural applications. Our range includes square recessed covers, flush-fit designs, and custom configurations engineered to meet specific load and access requirements.
Our manufacturing integrates automated cutting, stamping, welding, CNC machining, and laser processing, ensuring precise dimensions and consistent quality. We supply project managers, plant engineers, and distributors worldwide, supporting OEM/ODM orders with in-house tooling and material expertise.
We manufacture stainless steel manhole covers for utility access points, drainage systems, water supply networks, and underground tunnels. The material choice—typically SS304 or SS316—provides excellent resistance to corrosion, chemicals, and weathering, making these covers suitable for coastal, industrial, and high-traffic environments.
