A grille drain cover provides a finished, removable surface over linear drainage channels while allowing water to enter the system. Leiyuan supplies steel-reinforced high-density polyethylene drain grates in straight and bend options for landscape channels, swimming-pool surrounds, gutters and commercial drainage projects.
Grille Drain Cover for Commercial Drainage Projects
Combine an inner steel reinforcement with a molded plastic exterior for corrosion resistance, practical handling and an orderly architectural finish. Multiple sizes support project-specific channel widths, alignment and visual requirements.
Why Specify a Grille Drain Cover?
Sturdy and Corrosion Resistant
Inner steel provides reinforcement, while the molded plastic exterior supports corrosion-resistant service in suitable environments.
Easy Installation
The modular design is intended for simple placement without specialized tools, helping reduce installation complexity.
Multiple Sizes
DC25, DC30 and DC35 give designers a practical selection for different channel and landscape configurations.
Steel–Plastic Drain Grates
The original product is described as a special flat-steel and polyethylene assembly formed by high-pressure injection molding. Its commercial advantages include strength, corrosion resistance, fast drainage, easy installation, good plasticity and an elegant finished appearance.
When coordinated with pebbles, geotextile and the surrounding landscape, the grate can create a visually discreet drainage line. The complete channel, outlet, filter and sub-base must still be designed to handle the project’s expected water flow and loading.
Grille Drain Cover Performance Data
The figures below preserve the original page information. They are supplier-listed product values and should be verified against the current data sheet, test method and intended loading before specification.
| Property | Listed Value | Project Review |
|---|---|---|
| Material | High-density polyethylene and steel | Confirm material documentation required by the project. |
| Pressure strength | 400 kilonewtons; original equivalent 41 tons per square meter | Confirm test setup, support conditions and applicable load class. |
| Hardness | 86 | Confirm the hardness scale and test method. |
| Water drainage rate | 96 percent | Confirm definition and hydraulic test method. |
| Vertical circulating capacity | 50 cubic centimeters per second | Coordinate with channel and outlet capacity. |
| Water retention | 3.5 liters per square meter | Confirm relevance to the complete assembly. |
| Tensile strength | 250 megapascals | Confirm whether this value applies to the steel component or assembly. |

Grille Drain Cover Advantages
- Solid composite structure: an outer plastic profile combined with inner steel reinforcement.
- Corrosion-resistant finish: suitable for planned landscape and water-management environments after compatibility review.
- Simple installation: modular pieces can be arranged with limited tools.
- Convenient cleaning: the comb-shaped grid supports routine debris removal and access.
- Anti-slip and wear-resistant positioning: intended for long service in suitable applications.
- Architectural flexibility: straight and bend options support visually continuous drainage lines.
Grille Drain Cover Applications
Landscape Channels
Use beside planting, paving or decorative stone where a narrow, orderly drainage line is required.
Pool and Water Features
Coordinate material, slip resistance, drainage capacity and water chemistry for swimming-pool or landscape-pool surrounds.
Commercial Drainage
Apply to suitable gutters, ditches and anti-slip drain slots after verifying the expected loading and hydraulic performance.

Grille Drain Cover Installation Planning
- Confirm the channel, sub-base, outlet and finished levels.
- Check the required model, straight sections, bends and total quantity.
- Verify load conditions and secure approved technical data.
- Lay the channel to the designed fall and connect outlets.
- Position the grate sections and check alignment at every joint.
- Test drainage, clean the grid and document the completed installation.
Grille Drain Cover Maintenance
- Remove leaves, sediment and trapped debris at a project-defined interval.
- Inspect for movement, damage, blocked outlets or uneven support.
- Lift accessible sections carefully and clean the underlying channel.
- Replace damaged pieces and correct the cause of excessive loading.
- Keep maintenance records for high-traffic commercial locations.
Grille Drain Cover Specification Checklist
1. Define the Site
Provide application, plan, channel dimensions, straight and curved runs, expected traffic, water exposure and design flow.
2. Confirm the Product
Review DC25, DC30 or DC35, required bends, color, tolerances, supporting channel and any test documentation.
3. Plan the Order
Confirm pieces per meter, waste allowance, sample approval, packaging, destination, production schedule and delivery terms.
Grille Drain Cover FAQ
What is a grille drain cover made from?
This product is listed as a composite of high-density polyethylene and inner steel reinforcement, combining a molded exterior with structural support.
Which sizes are available?
The listed range includes DC25 at 250 millimeters, DC30 at 300 millimeters and DC35 at 350 millimeters. DC30 and DC35 are offered in straight and bend configurations.
Can it be used around a swimming pool?
Swimming-pool surrounds are a listed application. The designer must confirm slip resistance, load, water chemistry, drainage capacity, hygiene and local safety requirements for the exact project.
How do I calculate the quantity?
The original specification lists 20 pieces per linear meter. Send the total straight and curved lengths plus a plan so the quantity and bend requirement can be reviewed.
What should a quotation request include?
Include the model, total meters, number of bends, channel drawing, use environment, loading, required standards, destination, delivery date and packaging needs.
