Cast Iron Grates 1.5"

The Many Applications of 1.5” Cast Iron Trench Grates

Given cast iron’s abrasion resistance, durability, and other traits, it’s well-suited for a wide range of applications and diverse environments. Here are some of the many situations where our 1.5” cast iron trench grates are an excellent choice.

High-Traffic Areas

Parking garages, train stations, parking lots, and other spaces where people are constantly coming and going demand durable infrastructure, such as sturdy drainage systems. The good news is that our 1.5-inch cast iron trench grates are an effective solution for high-traffic locations in need of drainage. These grates, known for their durability and strength, will last without damage for years to come.

Places Where High-Load Bearing Is Needed

In areas where high-load bearing is necessary, like industrial facilities, shipping ports, and cargo bays, the right trench grate material and design are paramount. That’s why contractors frequently install cast iron trench grates along channel drains in these applications. The 1.5” grates support heavy machinery and large vehicles while seamlessly directing water flow away from critical surfaces.

Damp, Moist Environments

Outdoor applications like airports that are regularly exposed to rain and moisture and saltwater locations like seaports need trench drain systems that can endure constant exposure to water. Our 1.5-inch cast iron trench grates, with their corrosion-resistant properties, are an excellent choice for such conditions. They provide adequate drainage and hold up well over time.

Other Applications

Our 1.5” cast iron trench grates are frequently used in the following places:

• Loading Docks and Warehouses
• Manufacturing and Industrial Plants
• Access Roads for Commercial Businesses
• Gas Stations
• Parking Garages and Commercial Lots
• Fire Stations
• Dealerships and Auto Shops
• Parks and Pavilions

Our 1.5” Cast Iron Grates Follow ASME A112.6.3 Standards and Have an H20 Load Rating

When it comes to selecting components for an industrial or commercial drainage project, compliance with industry standards is non-negotiable. It guarantees that the products you install are safe, reliable, and have been rigorously tested to perform as expected. We are proud to state that our 1.5-inch thick cast iron trench grates are manufactured in accordance with ASME A112.6.3 standards and with an H20 load rating.

The American Society of Mechanical Engineers (ASME) sets the benchmark for quality and performance in many industries. The A112.6.3 standard specifically covers gratings and frames for drains so that consumers can feel confident their products will meet strict criteria for material quality, design, and load-bearing capability.

In addition to being meticulously constructed, our 1.5” cast iron grates are H20 rated, as defined by the American Association of State Highway and Transportation Officials (AASHTO). An H20 rating certifies that the grate can withstand a wheel load of 16,000 pounds or a total axle load of 32,000 pounds — the equivalent of a heavy-duty truck. This rating makes our grates suitable for roadways, loading docks, and any other area subjected to heavy vehicular traffic.

How 1.5” Cast Iron Grates Compare to Other Grating Materials

While various materials are used for trench grates, each has distinct characteristics that make it suitable for different applications. For heavy-duty industrial and commercial use, 1.5” thick cast iron stands out for its unique combination of strength, durability, and value.

• Cast Iron vs. Galvanized Steel: Galvanized steel is created by applying a protective zinc coating to steel to prevent rust. While it offers good corrosion resistance initially, this coating can be worn away over time by heavy traffic, friction, and chemical exposure, leaving the underlying steel vulnerable to rust. In contrast, cast iron’s strength is inherent to the material itself. It possesses superior strength and is far less likely to bend or deform under heavy, repetitive loads.
• Cast Iron vs. Stainless Steel: Stainless steel is renowned for its exceptional corrosion resistance and hygienic properties, making it the premier choice for food-grade, pharmaceutical, and highly corrosive chemical environments. However, these benefits come at a significantly higher cost. For general-purpose heavy-duty applications like warehouses, parking lots, and industrial plants where extreme sanitation is not the primary concern, cast iron provides comparable strength and durability at a much more economical price point.
• Cast Iron vs. Aluminum: Aluminum is lightweight, easy to handle, and naturally resistant to corrosion. These qualities make it a good choice for trench grates in pedestrian areas or environments where grates are frequently removed for cleaning. However, aluminum lacks the strength and rigidity of cast iron and is not suitable for areas with forklift or vehicle traffic. It will quickly deform or fail under the heavy loads that our 1.5” cast iron trench grating is designed to handle.
• Cast Iron vs. Fiberglass: Fiberglass offers excellent chemical resistance and is lightweight. Its main drawback is its lower load-bearing capacity. Therefore, for high-traffic, heavy-load areas, cast iron grates for drainage applications remain the more robust and reliable option.
