    Designed to support heavy loads, these grates are used to cover drains in sidewalks and roadways. Since they only require support on the two long sides, you can install them end-to-end over a long stretch.
    Choose a grate with a DIN load class rating that's suitable for your application.
    Style 1—Style 1 grates have small openings, so narrow shoe heels won't poke through or get stuck.
    Class B—Class B grates are suitable for areas with light vehicle traffic, such as driveways and parking lots.
    Class C—Class C grates can handle heavy truck traffic in roads and commercial zones.
    Class E—Class E grates are designed to withstand impact from heavy vehicles with solid tires, such as forklifts and cargo planes.
