Safety, durability and cost efficiency are important criteria when choosing gully grates for today’s busy built environments. Product features such as cycle friendly mesh designs, taper-lock frames, captive hinges and reversible grates aid performance and lead to the reduction of maintenance or replacement costs. Clark-Drain designs and produces gully grates to be highly efficient in clearing waterways as well as providing additional functional benefits which help improve operator safety and asset security.
The HA102/00 section of the Highways England Design Manual for Roads & Bridges provides a general guide to determining the length of road between gullies that can be drained by grating and kerb-side outlets to BS EN 124. We design our D400 products to comply to this. It takes into account the hydraulic design of road gratings and kerb inlets considering the flow of water parallel to the kerb and the efficiency of the grating in collecting the water. To help make product selection easy we follow the recommendation outlined in the advice note using the method of classifying gratings based on their hydraulic characteristics – Types P, Q, R, S or T. The advantage of this approach is that Designers and Specifiers are able to specify a grating type and be sure of achieving the required hydraulic performance based on their grating type calculations.
