Choose from four styles of grating designed to allow the 5″ Pro-Series to meet specific application requirements. For sidewalks, a heel-proof perforated grate is available that meets ADA requirements. The more popular grate, a light traffic slotted grate that comes in six colors (white, gray, black, sand, green, and brick red), is rated for the vehicular traffic seen in residential driveways and other light duty applications. A slotted cast iron grate can be used in some commercial situations because it is strong enough to bear the load of delivery trucks. Glass-reinforced nylon heavy traffic grates are available that withstand hard tire forklift traffic.
