Detailed introduction of Drainage Grating

parameter details

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.

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).

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.

 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.

 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.

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: 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: 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: 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 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.
