Gully gratings are designed to handle varying levels of load based on their application, and their load class ratings provide a clear standard for selecting the right product. These ratings are defined by the EN 124 standards, which classify gratings into categories such as A15, B125, C250, D400, and higher.

For pedestrian zones and bicycle paths, A15-rated gratings are sufficient, as they are designed for areas with minimal traffic. In contrast, areas such as car parks and urban streets often require C250 or D400-rated gratings, capable of withstanding vehicle weights without deformation.

In high-impact environments like industrial zones or airports, gratings with E600 or F900 ratings are essential to endure heavy loads from trucks and aircraft. Selecting the correct load class rating ensures durability, safety, and cost-efficiency, as under-specification can lead to product failure while over-specification may unnecessarily increase costs.

By understanding load class ratings, engineers and urban planners can make informed decisions when designing urban drainage systems that rely on gully gratings for effective water management and structural reliability.
