A drainage grille (also known as a drainage cover) is a critical component of a drainage system, typically made of metal (stainless steel, cast iron, brass, etc.), plastic, or composite materials. It is mainly used to block large debris such as fallen leaves, branches, and garbage from entering the drainage pipe, avoiding pipe blockage and ensuring smooth drainage. It is widely used in streets, parking lots, building entrances, shower areas, and other scenarios, and has various shapes such as square, circular, and rectangular to meet different needs.
Core strengths
High strength and durability: Made of high-quality stainless steel, sturdy cast iron and other materials, the stainless steel version can bear up to 8000 kilograms, suitable for high traffic scenarios such as industrial parks and commercial lanes, reducing replacement frequency and saving costs.
Efficient drainage: With a special opening design, the drainage capacity can reach 10000 liters per minute. The optimized hole pattern can prevent debris blockage and is suitable for rainy or flood prone areas.
Safe anti slip: Surface anti slip design, with a friction coefficient of at least 0.75 on rainy days or when exposed to industrial liquids, reducing the risk of pedestrians and vehicles slipping.
Customizable: Supports shape (square, round, rectangular), size, and hole pattern customization, such as providing special groove grilles for modern architectural complexes.
Strong corrosion resistance: Stainless steel or grille 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 or chemical scenes.
key parameters
1. Materials
Load bearing flat steel: Q235A carbon steel (high cost-effectiveness) or 304/316 stainless steel (stronger 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
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: Provides standard dimensions (standard width 995mm, including 5mm installation gap), supports customization.
3. Load bearing capacity
Light load: 25 tons/square meter, suitable for residential walkways, parks, and light vehicle parking lots.
Medium load: 70 tons/square meter, suitable for ordinary roads in the factory area where vehicles under 20 tons can pass.
Heavy load: 140 tons/square meter, suitable for high flow areas such as main roads and industrial docks.
4. Surface treatment
Hot dip galvanizing: 85 μ m zinc layer, with a normal service life of over 20 years.
Cold galvanizing: thin coating, suitable for low demand scenarios.
Spray painting: Multi color anti rust paint, balancing aesthetics and corrosion resistance.
5. Drainage and anti slip
Drainage efficiency: The maximum leakage area is 83.3%, and it can drain 1000 liters per square meter per minute under a rainfall of 50mm/h.
Slip resistance: In wet/oily environments, the friction coefficient should be at least 0.6.
Main application scenarios
Urban streets: installed in roadside drainage ditches, bearing the weight of vehicles, quickly draining rainwater, preventing water accumulation to ensure traffic and pedestrian safety.
Industrial park: The grilles in workshops and loading and unloading areas are resistant to chemical leaks and have strong durability, which can withstand the passage of heavy equipment.
Commercial buildings: The entrances of shopping malls/office buildings, parking lots, and basements are equipped with drainage systems, and anti slip surfaces can enhance safety.
Residential areas: Use lanes and sidewalks to meet drainage needs, and can be customized to meet aesthetic requirements.
Leisure facilities: Park fountains, amusement park trails, and sports venue changing rooms are quickly drained 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.
