About The Trench Grate Store

We price our grates per unit by size. The price will also depend on the material you choose, as different materials have different costs. You can see the cost of our trench drain grates at our shop.

Absolutely. At The Trench Grate Store, all of our trench drain grates can withstand harsh weather, including rain, saltwater, direct sunlight, freezing temperatures, and blistering heat. Give one of our experts a call to discuss your specific needs.

Our trench drain grates are made out of a variety of materials. You can choose from fiberglass, galvanized steel, stainless steel, aluminum, and cast iron. Depending on your drainage needs, you may benefit more from one of these types than others.

The best choice depends on factors like the expected traffic (load class), environmental conditions, chemical exposure, and budget. Here’s a breakdown of the materials we offer to help you decide:

• Fiberglass: It’s lightweight yet durable and resistant to corrosion, making it ideal for wastewater treatment plants, food processing facilities, pools, and coastal areas where there is no vehicle traffic.
• Galvanized Steel: It's best suited for areas with light to heavy traffic, such as parking lots, commercial garages, and industrial parks, where harsh chemical exposure isn't a primary concern.
• Stainless Steel: For applications where sanitation is a concern, stainless steel trench drain grates are the premium choice. They are commonly used in commercial kitchens, breweries, laboratories, and medical facilities.
• Cast Iron: When you need maximum strength and durability, cast iron is the answer. It can withstand extremely heavy loads, making it the standard for loading docks, highways, and industrial areas with frequent forklift or truck traffic.
• Aluminum: Lightweight and naturally rust-proof, aluminum grates are a great option for pedestrian areas and residential patios where there is no possibility of vehicle traffic.

Our trench drain grates are incredibly versatile and designed for a wide range of residential, commercial, and industrial environments. Essentially, anywhere you need to effectively manage surface water, our grates can do the job.

Here are some common applications:

• Driveways: Placing a trench drain at the entrance to a garage or at the bottom of a sloped driveway prevents water from pooling and causing damage.
• Lawns & Gardens: Trench drains can protect your landscaping by intercepting heavy water runoff from patios or roofs, preventing soil erosion and keeping your lawn from becoming oversaturated.
• Patios & Walkways: Keep your concrete patio, walkways, and pavers safe, dry, and usable by installing a trench drain. 
• Pool Decks & Outdoor Showers: Our metal channel drains are perfect for removing water quickly to reduce slip-and-fall risks.
• Commercial Applications: We supply heavy-duty trench drain grates for loading docks, warehouses, commercial kitchens, breweries, and food processing plants. You’ll also find our grates in parking garages, public plazas, and restaurant patios.

No matter the project, there is a channel drain cover that fits the need.

Yes, the terms “trench drain” and “channel drain” are often used interchangeably to describe the same type of linear surface drainage system. While there might be regional or manufacturer-specific preferences for one term over another, they all refer to a channel set into the ground with a grate on top to collect and move water.
