ISO9001 Prevent Rust Recessed Cover Square Cast Iron Manhole Covers

Production information:

The Recessed Square Cast Iron Manhole Cover is a durable and versatile access solution designed to seamlessly blend with surrounding pavement or flooring. Made from high-quality cast iron or ductile iron, it features a recessed design that allows for the insertion of matching materials such as concrete, tiles, or pavers. This creates a uniform and visually appealing finish, making it an ideal choice for areas where aesthetics are important, such as urban landscapes, commercial spaces, and residential properties. The cover is engineered to provide excellent load-bearing capacity, durability, and ease of maintenance.

Manufacturing Process

Material Preparation: High-quality pig iron and scrap iron are melted together, with magnesium added to create a ductile iron alloy.

Casting: The molten iron is poured into molds to form the basic shape of the manhole cover. Sand casting is a common method due to its precision and efficiency.

Heat Treatment: The cast pieces are treated with heat to improve strength and flexibility.

Surface Coating: Anti-corrosive coatings are applied to ensure longevity in various environments.

Quality Control: Each cover undergoes rigorous testing for load-bearing capacity, tensile strength, and dimensional accuracy.
