Frequently Asked Questions
Find answers to common inquiries regarding our composite solutions, structural specifications, and global logistics service.
Have a highly technical question or need customized engineering parameters?
Contact Our EngineersWhat are the key benefits of using composite manhole covers over cast iron?
Composite manhole covers are lightweight, slip-resistant, rust-free, and offer excellent electrical insulation. Additionally, they have zero scrap value which completely eliminates theft risks, ensuring public safety and reducing long-term maintenance costs.
Do your composite products comply with international load-bearing standards?
Yes, all of our composite manhole covers, trench systems, and drainage gratings are fully certified to comply with the European Standard EN 124, ranging from Class A15 (pedestrian use) up to F900 (heavy-duty airport and dock loading applications).
Can you customize dimensions, load classes, and molded logos?
Absolutely. Supported by our dedicated in-house mold R&D center, we offer comprehensive OEM and ODM customization services. We can design custom dimensions, reinforce load capabilities, and mold your proprietary brand logo directly onto the cover surface.
What high-performance materials are used in your manufacturing process?
We utilize high-grade Sheet Molding Compound (SMC) and Fiber-Reinforced Polymer (FRP) formulations. These composite materials are molded under high pressure and temperature with specialized resins to ensure supreme corrosion resistance and durability in extreme environments.
How can we request technical drawings and a wholesale quote?
You can submit your specifications directly through our contact form or via email. Please include the required measurements, EN 124 load class, and target quantity. Our engineering team will prepare detailed CAD drawings and a commercial proposal within 24 hours.
