Solid Cover Ductile Iron Manhole Cover For Gas & Air Tight Inspection
High Strength and Durability:
Made from high-grade ductile iron (e.g., EN-GJS-500-7 or QT500-7), known for its superior tensile strength, flexibility, and resistance to wear.
Complies with EN124 standards, supporting various load classes such as D400 and E600, making it suitable for heavy traffic areas.
Square Design:
The square shape allows for better alignment with square-shaped openings, offering a precise and secure fit.
Solid Structure:
The solid cover design enhances strength and durability, making it suitable for high-load applications.
Fully sealed to prevent water ingress and eliminate odor leakage, ensuring a clean and functional environment.
Anti-Theft Features:
Optional locking mechanism or hinged design prevents unauthorized access and accidental displacement, ensuring safety and security.
Anti-Slip Surface:
The cover features a textured pattern (e.g., grid, diamond, or custom anti-slip design) that improves traction and reduces the risk of slips and falls, even in wet conditions.
Corrosion Resistance:
Treated with anti-corrosion coatings like bitumen, epoxy, or powder coating, extending the product’s lifespan and ensuring reliable performance in harsh environments.
Eco-Friendly and Cost-Effective:
Made from recyclable materials, contributing to environmental sustainability.
Lightweight design compared to traditional cast iron covers, making installation and maintenance more efficient.
