The 302 x 302 x 75mm Hinged Ductile Iron Gully Grating C250 (25T) is a medium-duty surface drainage solution engineered for areas subject to regular vehicular traffic, such as car parks, commercial yards, driveways, and slow-moving industrial access roads. Featuring a clear opening dimension of approximately 300mm by 300mm and a sturdy 75mm frame depth, this square grating unit is designed to efficiently capture surface water run-off while withstanding moderate to heavy wheel loads.
 
Manufactured from premium-grade ductile iron, this assembly offers an exceptional strength-to-weight ratio, excellent impact resistance, and long-term durability compared to standard grey cast iron. Classified as C250 under BS EN 124 standards, it is fully certified to bear a maximum test load of 250kN (25 tonnes), making it completely suitable for parking areas, forecourts, and industrial sites frequented by cars, vans, and medium-weight commercial vehicles. The slotted surface design optimizes hydraulic water intake while blocking larger debris from entering and clogging sub-surface drainage systems.
 
Engineered for practical operation and site safety, the unit incorporates an integrated captive hinge mechanism that secures the grating to its frame during maintenance, preventing loss and streamlining routine debris clearance. Enhanced by a robust frame profile for secure bedding and stable load distribution, this professional-grade ductile iron gully grating delivers reliable structural performance, weather resistance, and total compliance with civil engineering standards.
