Custom-made product (special discharge manhole)

High-precision and high-durability "custom outlet box" shaped to meet on-site needs.

Properly control the energy of water flow and prevent downstream erosion. We will commercialize the original functions required for the outlet box. ▪ High strength and durability: Achieved a dense concrete structure that surpasses on-site casting through steam curing in the factory. It has a structure that is resistant to freeze-thaw cycles and wear. ▪ Reliable hydraulic performance: Smooth interior finishing enables smooth drainage. It prevents sediment accumulation and reduces maintenance burden. ▪ Consideration for the environment: Zero waste materials (formwork and leftover concrete) on-site. Clean construction is possible without polluting the surrounding environment. No two site conditions are the same. "Doesn't fit standard sizes," "requires special load conditions," "needs complex cutouts," "prefabrication of on-site casting. Custom solutions to shorten construction time"… Our custom-made solutions address such site challenges. With thorough quality control, we can flexibly respond to special shapes and large products. We also welcome consultations from the design stage. If you have any concerns, please feel free to contact us with just "one drawing."
