>> Features
1. Composite high strength structure design
Multi-layer reinforcement technology: glass fiber three-dimensional mesh reinforcement + mineral filler composite reinforcement, compressive strength up to D400 (EN 124), bending strength ≥ 85MPa (GB/T 23657).
2.Intelligent Load Matching: Serial load-bearing classes cover the A15-F900 standard (CJ/T 211-2005), and can be customized to meet overload scenarios such as airport runways and port terminals.
3.Lightweight Systems Engineering：Weight ratio optimization: the weight per unit area is only 1/4 of the same specification of cast iron manhole cover (typical 600mm round manhole cover weighs only 18kg).
4.Lifecycle load reduction: 65% reduction in transportation energy consumption, 300% increase in installation efficiency, support for manual handling without mechanical assistance (DIN 124-1).
5.Seismic cushioning design: elastic modulus up to 12GPa, effectively absorbing vehicle shock and vibration, reducing the damage rate of infrastructure.
6.Multi-dimensional noise reduction: The elastic contact interface makes the vehicle pass through noise ≤ 45dB (A), which is 60% lower than that of metal products (GB 3096).
