The drainage grille (also known as the drainage cover plate) is a key component of the drainage system, usually made of metal (such as stainless steel, cast iron, brass), plastic, or composite materials. Its core function is to prevent large debris such as leaves, branches, and garbage from entering the drainage pipe, avoid pipe blockage, and ensure smooth drainage. It is widely used in streets, parking lots, building entrances, and shower areas. Common styles include square, circular, rectangular, etc. to adapt to different scenarios.
1、 Core advantages
High strength material: Made of high-quality stainless steel, sturdy cast iron, etc., the stainless steel version can bear up to 8000 kilograms, suitable for long-term use in high flow areas such as industrial parks and commercial lanes, reducing replacement frequency and saving costs.
Excellent drainage performance: With a special opening design, the drainage rate can reach 10000 liters per minute. The optimized aperture and layout can prevent debris blockage and accelerate drainage, making it suitable for rainy or flood prone areas.
Anti slip safety: Surface anti slip treatment, with a friction coefficient of not less than 0.75 on rainy days or in the presence of industrial liquids, significantly reducing the risk of slipping and adapting to pedestrian and vehicular traffic areas.
Customizable: Available in various shapes and sizes such as square, rectangle, and circle, with customizable opening styles, such as providing special groove grilles for modern architectural complexes.
Strong corrosion resistance: Stainless steel or grid treated with anti-corrosion coating can withstand corrosive substances such as salt and acid, with almost no loss for more than 20 years, suitable for coastal areas and chemical plants.
2、 Key parameters of the product
1. Material
Load bearing flat steel: Q235A carbon steel (high cost-effectiveness and toughness) or stainless steel (304/316, better corrosion resistance) can be selected.
Horizontal bar: Q235A or 304 stainless steel can be selected, with shapes including circular, twisted square steel (5 × 5mm-8 × 8mm), square, and hexagonal to enhance stability.
2. Size specifications
Flat steel: thickness 3-10mm (such as 25 × 3mm-100 × 10mm), width depending on load-bearing requirements.
Grille: The center distance of the flat steel is 30/40/60mm, and the spacing between the horizontal bars is 100/50mm.
Overall: Regular sizes can be customized in stock, with a standard width of 995mm (including a 5mm installation gap).
3. Load bearing capacity
Lightweight: 25 tons/square meter, suitable for residential walkways, parks, and lightweight parking lots.
Medium size: 70 tons/square meter, suitable for ordinary roads in the factory area where vehicles under 20 tons can pass.
Heavy duty: 140 tons/square meter, suitable for high flow areas such as main roads and industrial docks.
4. Surface treatment
Hot dip galvanizing: Zinc layer of 85 μ m, with a normal environmental service life of over 20 years.
Cold galvanizing: thin coating, suitable for low demand scenarios.
Spray painting: Various colors of rust proof paint, balancing aesthetics and corrosion resistance.
5. Performance indicators
Drainage efficiency: leakage area reaches 83.3%; When the rainfall is 50mm/h, it can drain 1000 liters per square meter per minute.
Anti slip performance: Surface embossing or coating treatment, friction coefficient not less than 0.6 in humid/oily environments.
3、 Main application scenarios
Urban streets: installed in roadside drainage ditches, bearing the weight of vehicles, quickly draining rainwater, and avoiding water accumulation.
Industrial park: The workshop and loading and unloading area grilles are resistant to chemical leaks and can withstand the passage of heavy equipment.
Commercial buildings: shopping malls, office entrances, parking lots, and other scenes with efficient drainage and anti slip properties.
Residential area: lanes and sidewalks can be customized to meet aesthetic needs.
Leisure facilities: Park fountains, amusement park trails, and other areas with quick drainage to maintain a clean and safe environment.
Q: What's the lifespan of the steel grilles?
A: Our steel grilles, especially when hot - dip galvanized, can last over 20 years in normal conditions. Their robust material ensures long - term durability against wear and corrosion.
Q: Are they easy to install?
A: Yes. Standard - sized grilles come with a 5 - mm installation gap for easy fitting. They can be quickly placed in position. Custom - sized ones also have straightforward installation procedures.
Q: How to clean the grilles?
A: Regularly remove debris with a broom or shovel. For stubborn dirt or stains, use a mild detergent and water. In industrial settings, power - washing may be needed to handle heavy - duty grime.
Q: Can the grilles bear heavy loads?
A: Absolutely. They're designed with different load - bearing capacities. Heavy - duty grilles can withstand up to 140 tons/m², suitable for areas with heavy - truck traffic.
Q: Do you offer customization?
A: Yes, we provide customization in terms of size, shape, and hole patterns. This allows the grilles to meet specific project requirements, whether for aesthetics or functionality.
