Cast Iron Gratings

When it comes to selecting materials for trench drain systems, cast iron grates are consistently among the top choices for engineers, architects, and contractors. Known for their exceptional durability and strength, cast iron grates are designed to withstand the demands of heavy-duty loads and applications while maintaining optimal drainage performance.

One reason cast iron grating is able to perform so well is due to its natural iron oxide coating. This coating forms a protective layer over time, offering increased resistance to corrosion and extending the lifespan of the grate even in harsh outdoor and industrial environments.

At The Trench Grate Store, we offer a wide variety of cast iron grates to suit a range of trench drain systems. With numerous sizes and configurations available, these grates can meet light, medium, and heavy-duty applications. So, shop online today and experience the difference of quality drainage parts at an affordable price.

How Cast Iron Grates Are Manufactured

When cast iron grating is manufactured, high-quality iron and alloy materials are melted down and poured into sand molds to form the structure’s load-bearing design. Our cast iron trench grates are made of several molded bars, and their construction takes into account wear and weathering patterns and total estimated loads for outstanding performance. Once cooled and solidified, the grates are removed from the molds and go through a series of finishing steps, such as cleaning and grinding. The end result is a robust product that not only delivers long-term performance but also meets regulatory requirements.

Common Applications for Cast Iron Trench Grating

  • Area Drains: Our cast iron grating can efficiently channel water away from paved surfaces, sidewalks, and building entrances. The 1-inch thick grates are designed for all types of medium to heavy traffic areas.
  • Floor Drains: The durable nature of cast iron makes it a preferred choice for floor drains in commercial kitchens, warehouses, and manufacturing facilities. The material can endure frequent exposure to moisture, heavy equipment, and cleaning chemicals.
  • Trench Drains: Our extra heavy-duty cast iron grates are ideal for trench systems in roadways, loading docks, airports, and parking garages since they are extremely durable and highly efficient.

The Benefits of Cast Iron Trench Grates

Cast iron is an ideal material for trench grates due to its exceptional durability and resistance to corrosion, but those aren’t the only benefits of this material. Here’s a closer look at why so many contractors, construction companies, and facility managers rely on cast iron trench grates:

Incredibly Durable

Thanks to the strength of cast iron and its natural resistance to wear and tear, these grates can endure high-impact loads and prolonged use in challenging environments. This translates into less frequent repairs and replacements.

Corrosion Resistant

The formation of an iron oxide coating over time acts as a self-healing barrier that slows the effects of moisture and oxidation. This reduces maintenance requirements and increases the longevity of the grate, making cast iron grates a cost-effective long-term investment.

Versatile

The robust nature of cast iron makes it highly suitable for a wide array of applications. Whether used in pedestrian walkways or high-traffic roadways, these grates provide reliable performance without warping or cracking.

Easy to Install & Maintain

Cast iron trench grates are known for their ease of installation and low maintenance requirements. Many grates are designed to fit standard trench drainage systems, reducing the need for custom fabrication or complex tools. Once installed, their robust nature means they require minimal upkeep, saving time and resources over the life of the product.

Highly Effective

Their structural design allows for efficient water flow while preventing debris from entering the drainage system. Whether managing runoff from a large paved area or controlling indoor drainage in a facility, cast iron drainage grates provide dependable performance in moving wastewater quickly and effectively.

Additional Details on Cast Iron Grate Placement

Cast iron trench grates are particularly well-suited for installation in areas prone to water accumulation, such as parking lots and driveways. The design and construction of cast iron grates facilitate efficient water runoff, preventing water logging that could lead to potential flooding.

What Is ASME A112.6.3?

ASME is a standard that defines design requirements for various drains that are typically in non-residential areas directly adjacent to or outside building structures. It provides guidance for product design, materials, finishes, top-loading classifications, outlet types, and definitions.

More specifically, these standards outline requirements for the materials used in the manufacturing of trench grates — emphasizing durability and structural integrity. The standards also provide guidelines for the safe installation of trench grates in various environments, including parking lots and driveways. 

By adhering to the ASME A112.6.3 standards, we ensure that the cast iron trench grates we supply clients meet the necessary criteria for withstanding exposure to environmental factors and heavy loads while satisfying drainage requirements. Compliance with these standards contributes to the overall effectiveness and reliability of cast iron trench grates so that they can properly provide a safe and durable drainage solution.
