Designed for Heavy Traffic Roads
Stormwater inlets on city main roads play an important role in flood control during heavy rainfall. These drainage points are usually installed along road edges and are exposed to continuous traffic loads every day. Bus lanes, freight routes, and logistics areas create additional pressure on drainage systems.
Our Dingjian heavy duty stormwater grates feature an extra-thick reinforced structure designed for demanding road conditions. The load capacity reaches 360 kN, making them suitable for city main roads, logistics heavy-duty routes, and freight parking lot drainage systems. The reinforced design maintains structural stability under long-term heavy loads without bending or cracking.
Three Structural Improvements for Higher Strength
The design includes three structural improvements to enhance product strength and durability. First, the load bars are increased in height to improve bending resistance. Second, the cross bars are arranged with optimized spacing to increase overall rigidity. Third, the edges feature a reinforced thicker structure to reduce deformation under pressure.
These improvements help the grate remain flat and stable even in areas with frequent heavy truck traffic, such as logistics parks and freight lanes. The improved structure reduces replacement frequency and helps lower long-term maintenance costs.
Wide Slots for Fast Drainage
Efficient drainage is essential for flood prevention on major roads. During heavy rainfall, surface water must enter drainage systems quickly to avoid flooding and traffic interruptions.
Our heavy duty stormwater grates use optimized slot designs to achieve high drainage efficiency while maintaining safe walking conditions. The grate is manufactured as a one-piece casting without welded joints or assembled sections. This structure eliminates potential weak points caused by welding and provides better resistance against impact loads during long-term outdoor use.
High-Grade Material for 360kN Load Capacity
We use high-quality ductile iron to meet the requirements of 360 kN load capacity. The material provides excellent strength, impact resistance, and long-term durability for heavy-duty drainage applications.
We apply strict controls during the nodulizing process to ensure consistent graphite structure and reliable mechanical performance. Each production batch undergoes load testing to verify that the product meets required capacity standards.
Regular orders are shipped within 15 to 25 days. We use iron pallets for export packaging to ensure safe transportation. We also support customized sizes and slot widths according to different project requirements.
