Products Description
This heavy‑duty ductile‑iron gully grating adopts lattice‑style open‑work architecture and is supplied in multiple dimensional variants, covering square and rectangular configurations. Its top surface incorporates anti‑skid textures and brand embossing; certain variants are fitted with lifting cut‑outs to facilitate field placement.
Fabricated from premium‑grade ductile iron, the unit receives anti‑corrosion surface remedies such as hot‑dip galvanisation and epoxy‑asphalt finishing, with optional colour finishes including silver and black tones.
Functioning as indispensable hardware within municipal drainage frameworks, heavy‑duty ductile‑iron gully gratings mainly serve as cover elements for roadside and plaza drainage trenches. They safeguard unobstructed passage for pedestrians and vehicular traffic, whilst enabling efficient rainwater capture and rapid discharge.

Key Features
High Load-Bearing Capacity
Ductile iron substrate delivers outstanding tensile performance and superior impact toughness. Heavy‑grade variants can endure vehicle loads of over 40 tons, fully complying with the load-bearing requirements of urban arterial roadways.
01
Efficient Drainage
Its perforated lattice structure delivers an expansive water passage area, enabling expedited fluid evacuation during intense downpours and effectively mitigating road surface ponding risks.
02
Anti-Slip and Anti-Theft
Diamond and strip textured surface profiling enhances surface friction coefficients, delivering reliable anti-slip performance for both pedestrian and vehicular traffic. Coupled with anti-theft locking devices, the interlocking structural design effectively deters unauthorised removal and theft.
03
Corrosion-Resistant and Durable
Hot‑dip galvanizing and epoxy coating treatments deliver robust tolerance against acid, alkali and humid corrosion factors, securing long‑term outdoor operational durability.
Advantages
1. Superior Safety & Structural Reliability
Boasting exceptional load-bearing performance, the grating eliminates structural collapse hazards under heavy loads. The integrated anti-slip surface texture guarantees stable, safe passage for both pedestrians and vehicles, solidifying dependable operational safety for municipal infrastructure systems.
2. High-Efficiency Drainage Performance
The oversized water-passage area and hollow lattice architecture deliver drastically enhanced drainage capacity compared with conventional cast iron covers. It swiftly evacuates rainwater accumulation and substantially alleviates urban road ponding and flooding issues during extreme rainfall.
3. User-Friendly Maintenance & Installation
Reserved lifting apertures simplify on-site installation, routine debris cleaning and daily upkeep procedures. Routine maintenance can be completed efficiently without reliance on large-scale mechanical equipment, greatly saving construction time and labour costs.
4. Outstanding Environmental Adaptability
Engineered with superior weather resistance and environmental tolerance, the product maintains stable structural performance in complex working scenarios, including urban arterial roads, pedestrian walkways and industrial zones, supporting long-term outdoor service.
5. Optimized Lifecycle Cost Control
Excellent material durability and corrosion resistance minimize frequent replacement and secondary maintenance expenses, lowering overall long-term operational costs. Meanwhile, customizable specification solutions flexibly adapt to diverse project budget and construction demands.
Application Scenarios
Municipal Roads: Rainwater inlets on urban main and secondary roads facilitate rapid drainage of surface water, ensuring smooth traffic flow during rainy weather.
Commercial Districts and Squares
Drainage covers on pedestrian streets and commercial plazas prioritize both pedestrian safety and drainage efficiency.
01
Residential Communities and Campuses
Drainage systems in residential roads, parking lots, and playgrounds prevent water accumulation from affecting residents' lives and campus activities.
02
Industrial and Logistics Parks
Drainage trenches on factory roads and logistics channels withstand the weight of heavy vehicles such as forklifts and trucks, ensuring safe production and transportation.
03
Overseas Export Projects
Suitable for municipal infrastructure projects in Southeast Asia, Europe, and other regions, complying with local standards such as EN124, and supporting customized markings in Thai, English, and other languages.
04
Maintenance Procedures
Regular Cleaning
Clean the dirt and debris from the grate gaps every 3-6 months to prevent drainage holes from becoming blocked.
Inspect for Wear
Inspect the surface coating and load-bearing structure annually. If the coating is peeling or cracked, perform anti-corrosion treatment or replace the grate promptly.
Emergency Procedures
Conduct thorough inspections before and after heavy rainfall. If drainage is poor, immediately clear any blockages; if the grate is damaged, temporarily cordon off the area and replace it as soon as possible.
Anti-theft Reinforcement
For grates in areas prone to theft, install anti-theft locks or use anti-displacement devices to reduce the risk of loss.
Production process
Production process
1. Mold Making：Sand molds or metal molds are manufactured according to the customer's customized dimensions, patterns, and logos.
2. Raw Material Melting
3. Casting and Forming
4. Post-processing and Finishing：Sandblasting, polishing, and defect repair.
5. Anti-corrosion Coating Treatment：Hot-dip galvanizing and epoxy asphalt spraying are used; some products also utilize electrostatic spraying for a more aesthetically pleasing colored coating.
6. Quality Inspection：Load testing, appearance inspection, and dimensional accuracy testing.
7. Packaging and Warehousing：Qualified products are packaged with rust-proof materials and packed in pallets or wooden crates to prevent damage during transportation.
