Drainage Grating Product Introduction

Dimensions

Flat Steel: Thickness ranges from 3 - 10mm (e.g., 25×3mm - 100×10mm), and width varies based on load requirements.

Grid: The center - to - center distance of flat steel can be 30/40/60mm; cross - bar spacing is 100/50mm.

Overall: Standard sizes are available, and customization is possible. The standard width is 995mm with a 5mm installation gap.

Material

Load - Bearing Flat Steel: We offer Q235A carbon steel for a cost - effective strength option, or stainless steel (304/316) for better corrosion resistance.

Cross Bar: Available in Q235A or 304 stainless steel, and can be round, twisted square (5×5mm - 8×8mm), square, or hexagonal steel for better stability.

Load - Bearing Capacity

Light - Duty: With a capacity of 25 tons/m², it's suitable for residential walkways, parks, and light - vehicle parking areas.

Medium - Duty: Rated at 70 tons/m², it's ideal for factory areas and ordinary roads with vehicles weighing less than 20 tons.

Heavy - Duty: Can bear 140 tons/m², designed for heavy - traffic areas like main roads and industrial docks.

Surface Treatment

Hot - Dip Galvanizing: Has an 85μm zinc coating, providing a lifespan of over 20 years under normal conditions.

Cold Galvanizing: Offers a thin coating for less - demanding applications.

Painting: Uses anti - rust paint in various colors for both aesthetics and corrosion prevention.

Drainage Efficiency

Leakage Area: Up to 83.3%, enabling fast water runoff.

Example: Drains 1,000 liters of water per minute per square meter at a rainfall rate of 50mm/h.

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: 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.

Applications

Urban Streets

Steel grilles installed in road gutters can bear vehicle weights and quickly drain rainwater, preventing waterlogging and ensuring the safety of traffic and pedestrians.

Industrial Plants

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

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 meet aesthetic requirements while keeping 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.
