Heavy Duty Grating

Heavy Duty Grates

Grates for Extreme Loads

Heavy-duty grates come in a broad range of shapes, sizes, heights and materials. Some have larger flow areas while others are designed for safe pedestrian crossing.

The majority of these grates are made of ductile iron or gray iron. However, it’s not unusual for stronger grates to be made of galvanized or stainless steel.  There are pros and cons to each style and the grate you select will be dependent upon many factors. Custom options are also available. Feel free to contact our experts to help you determine which grates will work best for your project.

Considerations

  • Who Goes There
    It's important to know what type of traffic is going across a grate. Some need to be able to handle semi-traffic but have a surface that accommodates heel traffic.
  • Rustic Rust
    Most heavy-duty grates arrive in the middle of their natural oxidation process. The settling of rust depends heavily on the material makeup as well as regional conditions.
  • Heavy Duty
    Simply put, these grates are designed for heavy traffic loads with the ability to accept large amounts of run-off.
