Concrete products: drop structures, slope boxes / orifice boxes, flow regulation boxes

No waste materials, no environmental pollution! Achieving clean construction with unique technology.

Our company manufactures concrete products such as custom drop structures and gradient structures (for field improvement projects) tailored to the site environment, as well as orifice structures and flow control structures (for rainwater, etc.). Being precast allows for quick site restoration, shortening construction periods and reducing running costs. We have numerous installation records in agricultural roads, sidewalks, roadways, premises, and planting areas. If you have drawings or rough plans, we can consider precasting and provide estimates, so please feel free to contact us when needed. 【Features】 ■ Challenge to "Zero On-Site Casting" - With side pipes, multi-stage drops, and angled connections, we can form and deliver even the most complex shapes exactly as per the drawings. ■ Reduce construction time from "several weeks" to "several hours" - Cut down on downtime waiting for curing; backfill on the same day of installation and proceed to the next phase. ■ Improved water tightness - The precise concrete produced in the factory and accurate openings reduce the risk of water leakage from joints, which is a concern with on-site casting. *For more details, please download the PDF or feel free to contact us.
