More About ASME A112.6.3

Cast iron is an ideal material for trench grates due to its exceptional durability and resistance to corrosion. The robust nature of cast iron makes it highly suitable for a wide array of locations, as this material’s ability to withstand heavy loads and resist wear ensures that the trench grates remain functional over time — even in high-traffic areas. 

The exposed nature of these grates in parking lots and driveways exposes them to various environmental conditions, including moisture and debris. Cast iron’s resilience makes it well-equipped to endure such conditions without compromising its structural integrity. Additionally, the installation of cast iron trench grates is relatively straightforward and their maintenance is easy as well. The combination of these traits help create a safe and secure environment for pedestrians and vehicles alike.

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 trench grates facilitate efficient water runoff, preventing water logging that could lead to potential flooding. As such, the safe and reliable drainage system provided by these grates enhances the overall safety of such environments. 

Additionally, the exposed nature of driveways and parking lots demands a trench grate solution that can withstand external elements while effectively managing water flow. Cast iron trench grates, with their sturdy construction and water-draining capabilities, fulfill this need, ensuring a durable and reliable solution for water drainage in these specific locations.

More About 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 of 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, heavy loads, and 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.
