>> Features
1. Excellent Electrical Insulation: Suitable for power networks, avoiding electric shock risks.
2. Non-Magnetic Materials: Does not interfere with communication signals, ensuring normal equipment operation.
3. Corrosion-Resistant Design: Extends product lifespan, suitable for harsh environments.
4.Zero recovery value anti-theft: Glass fiber reinforced unsaturated polyester resin (SMC) composite material is used, which does not contain metal components, completely eliminating the theft motive caused by scrap iron recycling, and reducing the theft rate by more than 98% compared with traditional cast iron manhole covers.
5.Extreme environment verification: Through low temperature brittleness test at -40 ° C and high temperature creep test at 80 ° C, maintaining zero displacement records in severe climates such as typhoons and rainstorms.
6.Green manufacturing process: Production energy consumption is only 1/5 of cast iron manhole cover, 100% recyclable materials comply with the European Union RoHS directive.
7.Directional drainage system: V-shaped diversion tank and nano-hydrophobic coating work together to achieve 200mm/h rainfall with zero water accumulation, and winter anti-icing performance is increased by 60%.

>> Customer Cases & Reviews
Trusted by Global Leaders
Our composite manhole covers are used in major infrastructure projects worldwide. Here’s what our customers say:
"After 3 years of field testing, SMC composite manhole covers far outperform traditional cast iron manhole covers in Vancouver's rainy climate and saline environment! Zero rust, zero deformation, and anti-slip design reduce winter accident rates by 40%. Lightweight features allow our maintenance team to operate alone, greatly improving municipal operation efficiency. Highly recommended for high humidity coastal cities!"
— James Wilson, Municipal Projects Engineer
“In the face of frequent earthquakes, the elastic modulus (≥ 12,000 MPa) and fatigue resistance of SMC manhole covers demonstrate amazing advantages.
Maintaining structural integrity after a magnitude 7 earthquake
• Perfect match with the thermal expansion coefficient of asphalt pavement
• Noise reduction reduces nighttime maintenance complaints by 65%
It has become standard for underground pipe gallery systems in Japan! "
— Tanaka Hiroshi, Minister of Technology
