Customized Rectangle Manhole Covers for Precision Engineering Solutions
Jinlong Foundry specializes in manufacturing customized rectangle manhole covers tailored to meet diverse industrial and municipal requirements. Engineered for durability and functionality, our rectangular designs optimize space utilization while maintaining superior load-bearing capacities (B125 to F900 ratings). Unlike standard circular covers, our custom rectangle manhole covers provide precise alignment with modern urban infrastructure layouts, particularly suited for trench drainage systems, utility access points, and traffic-sensitive zones.
Crafted from high-grade ductile iron, stainless steel, or composite materials, each cover undergoes rigorous stress analysis to ensure compliance with EN124, ASTM, and ISO standards. We offer customized solutions including unique dimensions (up to 1200mm x 800mm), anti-slip textures, locking mechanisms, and corrosion-resistant coatings. Our engineering team collaborates with clients to integrate branding elements, safety markings, or RFID tracking systems without compromising structural integrity.
Ideal for airports, smart cities, industrial parks, and renewable energy facilities, our rectangle-shaped manhole covers enhance safety and accessibility while reducing long-term maintenance costs. Clients benefit from 3D modeling support, rapid prototyping (10-15 business days), and volume production scalability.
