Classification of Sewer Drain Grates

Sewer drain grates are classified based on material and shape:

Material-based classification:

Hot-dip galvanized sewer drain grates

Stainless steel sewer drain grates

Plastic-coated sewer drain grates

Shape-based classification:

Standard sewer drain grates

U-shaped sewer drain grates

Pipe-shaped sewer drain grates

Openable sewer drain grates

Product Dimensions

When selecting the appropriate sewer drain grate, it’s essential to consider the following:

The length of the flat steel should align with the direction of load-bearing (support). Determine the steel length based on the width of the drain or well.

For the long drainage or well openings, standard plate widths of 995mm with a 5mm gap between plates are recommended.

In cases where the length of the drainage or well opening is less than 1 meter, the dimensions should be determined based on standardized measurements.

The choice of steel grid plate type should be based on the width of the drain or well and the load-bearing requirements.

Standard-sized sewer drain grates are recommended for design and construction, while custom specifications can be tailored to specific needs.

Materials Used

Key materials used in sewer drain grates include:

Flat steel: Made from Q235A or stainless steel, available in various profiles such as plain, anti-slip, and section I. Common specifications include 205, 255, 253, 325, 325, 405, 403, 505, 655, 756, 1008, and 10010.

Crossbars: Made from Q235A or 304 stainless steel, available in round, twisted square, square, or hexagonal profiles.

Concrete: Reinforced concrete with strength reaching C25/C30/C35. It offers robust load-bearing capabilities, cost-effectiveness, and ease of maintenance.

Key Features

Sewer drain grates come with a multitude of advantages, making them the preferred choice for various applications:

Aesthetic design: Their sleek, silver appearance and modern lines contribute to their visual appeal.

Optimal drainage: With a water leakage area of up to 83.3%, they outperform cast iron grates.

Hot-dip galvanization: Their strong rust resistance minimizes maintenance and replacement needs.

Anti-theft design: Hinged connections between the cover and frame enhance security and facilitate easy access.

Cost savings: These grates offer cost-effective solutions compared to cast iron when handling heavy loads, reducing theft or breakage replacement costs.

High strength: Their superior strength and resilience make them suitable for large-span and heavy-load environments, such as docks and airports.

Diverse specifications: Sewer drain grates come in various sizes, shapes, and configurations to meet different environmental, load, span, and dimensional requirements.

Classification

Steel grid plate sewer drain grates typically consist of fixed frames and movable steel grid plates. They can be equipped with fasteners and anti-theft devices as needed.

GT-type sewer drain grates: These grates are categorized into side drains and cross drains, depending on the vehicle’s direction. Side drains bear flat steel perpendicular to the direction of vehicle travel, while cross drains bear flat steel parallel to the direction of vehicle travel.

GU-type sewer drain grates: Ideal for most standard concrete-built drains without edge openings, GU-type grates are simple, cost-effective, and do not require special edge openings.

GM-type sewer drain grates: These grates are suitable for rainwater wells, dust and sand wells, and sewage wells in facilities such as roads and municipal areas. GM-type grate covers can be designed as flip-up, typically with an opening angle of 110 degrees. Grates with corner brackets provide both anti-theft features and simplified procedures.

Reinforced concrete sewer drain grates: These grates are designed for road and municipal use, offering adjustable dimensions and strength.

Conclusion

In the world of infrastructure and construction, sewer drain grates have emerged as versatile, cost-effective, and high-performing solutions. With a focus on aesthetics, functionality, and durability, they have proven to be indispensable in diverse applications, offering a superior alternative to traditional cast iron grates. Their adaptability, strength, and varied specifications make them an ideal choice for projects of all sizes, ensuring efficient drainage and enhancing the safety and aesthetic appeal of our urban landscape.
