Designed for Long Drainage Channels with Heavy Loads
Long drainage channels on main roads, industrial facilities, and large factory areas are exposed to heavy vehicle traffic and high water flow volumes. These applications require grates that can withstand concentrated loads and maintain long-term structural stability.
Our ductile iron trench grate features a heavy-duty thickened design. The size is 450 × 750 mm, providing excellent coverage for large drainage channels. The reinforced structure is suitable for long-distance drainage systems that require high load capacity and reliable performance.
Thickened Plate Provides Extra Strength
The thickened plate structure is a key feature of this ductile iron trench grate. We increase the overall thickness and reinforce the edge sections to improve load-bearing performance.
The stronger plate design provides better resistance against impact loads and external pressure. Even when heavy objects fall onto the surface, the grate maintains structural integrity without easily cracking or deforming.
The large 450 × 750 mm size covers more drainage width, reducing the number of joints required along long channels. Fewer connection points improve overall stability and simplify installation.
Ductile Iron Resists Scour Wear
Ductile iron provides excellent resistance against wear in demanding drainage environments. During heavy rainfall, water mixed with sand and debris can flow across the grate surface at high speed and create continuous abrasion.
The high-density ductile iron structure offers strong hardness and wear resistance, helping maintain the original structure after long-term exposure to water flow and debris impact.
The one-piece casting design eliminates welded joints and reduces potential weak points. This improves reliability and helps extend service life in heavy-duty drainage applications.
Strong Large-Scale Casting Capability
We have strong large-scale casting capabilities for heavy-duty trench grates. Our melting and casting equipment supports the production of large ductile iron components with consistent quality.
Our heavy-duty thickened grates undergo appearance and dimensional inspections before shipment to ensure they meet project requirements. Regular orders are shipped within 15 to 25 days.
We use iron pallet packaging for safe land and sea transportation. We also support customized non-standard sizes and structures according to different drainage channel widths and project requirements.
