Detailed introduction of Drainage Grating

Product Details

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.

FAQs：

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: 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.

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: 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.

Applications

Urban Streets

Steel grilles installed in road gutters can withstand the weight of vehicles and quickly drain rainwater. This prevents waterlogging, ensuring the safety of both traffic and pedestrians.

Industrial Plants

In factory workshops and loading docks, the corrosion - resistant nature of our gratings can handle chemical spills. Their high durability also allows them to withstand the traffic of heavy equipment.

Commercial Buildings

When installed at mall and office entrances, parking lots, and basements, they effectively drain water. The non - slip surfaces enhance safety and prevent accidents.

Residential Areas

For driveways and sidewalks, our gratings offer a practical drainage solution. Custom designs can be created to match the aesthetic requirements while keeping the areas dry.

Recreational Facilities

Around park fountains, playground walkways, and sports - field changing rooms, they quickly drain water, maintaining a clean and safe environment for visitors.
