Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • EN124 Compliance & Heavy-Duty Support: Designed to meet EN124 standards, this D400-class cast-iron manhole cover withstands heavy vehicular traffic, ensuring safe access to underground utilities like sewers and drainage systems.
  • Integrated Locking System: Features a built-in locking mechanism for enhanced security, preventing unauthorized access to critical infrastructure.
  • Multi-Purpose Design: Textured, non-slip surface and ventilation holes ensure safety, stability, and drainage efficiency in diverse environmental conditions.

Key features

  • 1. Durable Ductile Iron Construction

    • With its heavy-duty ductile iron material, you can ensure superior strength and corrosion resistance compared to traditional cast iron models*. The EN124-compliant design withstands harsh environmental conditions and heavy traffic, extending the cover’s lifespan in demanding applications.

  • 2. High Load Capacity for Industrial Use

    • With a D400 load rating, you can support axle loads up to 40 tons*, far exceeding the 20-ton capacity of standard residential covers. This makes it ideal for commercial and industrial settings requiring heavy-duty infrastructure protection.

  • 3. Certified Safety & Compliance

    • With CE certification and EN124 compliance, you can guarantee adherence to international safety and quality standards, unlike uncertified alternatives. This ensures reliable performance in regulated environments.

  • 4. Integrated Locking System for Enhanced Security

    • With the built-in locking mechanism, you can prevent unauthorized access and vandalism, offering superior security compared to non-secured manhole covers*.

  • 5. Customizable & Slip-Resistant Design

    • With a textured, non-slip surface and customizable specifications (e.g., size, weight), you can adapt to diverse scenarios—from urban streets to industrial complexes—while maintaining safety and stability.
