Detailed introduction of Drainage Grating

Parameter Details

1. Material selection

Load bearing flat steel: Q235A carbon steel (cost-effective) or 304/316 stainless steel (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, which can enhance stability.

2. Size specifications

Flat steel: thickness range 3-10mm (such as 25 × 3mm to 100 × 10mm), width set according to load-bearing requirements.

Grille: The center spacing of the flat steel is 30/40/60mm, and the spacing of the horizontal bars is 100/50mm.

Overall: There are standard sizes available (standard width 995mm, including 5mm installation gap), and customization is also supported.

3. Load bearing grade

Light load: 25 tons/square meter, suitable for residential walkways, parks, and light vehicle parking areas.

Medium load: 70 tons/square meter, suitable for factory areas and ordinary roads for vehicles under 20 tons.

Heavy load: 140 tons/square meter, suitable for high load areas such as main roads and industrial docks.

4. Surface treatment

Hot dip galvanizing: The thickness of the zinc layer is 85 μ m, and the normal service life exceeds 20 years.

Cold galvanizing: The coating is relatively thin, suitable for scenarios with lower requirements.

Spray paint: There are various colors of anti rust paint, which are both beautiful and corrosion-resistant.

5. Drainage and anti slip performance

Drainage efficiency: The maximum leakage area is 83.3%, and under rainfall conditions of 50mm/h, it can drain 1000 liters per square meter per minute.

Slip resistance: In wet or oily environments, the friction coefficient should not be less than 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.

Main application scenarios

Urban streets

Installed at the roadside drainage ditch, capable of bearing the weight of vehicles, quickly draining rainwater, preventing water accumulation, and ensuring traffic and pedestrian safety.

Industrial park

The grilles in workshops and loading and unloading areas can withstand chemical leaks and have good durability, which can withstand heavy equipment driving.

Commercial buildings

Shopping malls, office entrances, parking lots, and basements use it for drainage, and anti slip surfaces can improve safety.

Residential areas

Use it to solve drainage problems for lanes and sidewalks, and can meet aesthetic needs through customized design.

Leisure facilities

Park fountains, amusement park trails, and sports venue changing rooms are quickly drained to maintain a clean and safe environment.
