List of products by brand Frost Drainage

Frost Drainage, has over 50 years of expertise in providing high-quality, durable drainage solutions for commercial and public buildings.

Frost Drainage manufactures a robust range of cast iron, ductile iron and steel drainage components engineered for commercial, industrial and infrastructure environments. At Gutter Centre, we supply the full Frost Drainage portfolio, chosen for its long-term structural durability, load-bearing performance and ability to handle demanding site conditions. These systems are designed to provide reliable surface water management in areas exposed to heavy traffic, consistent impact, and weather extremes.

Cast Iron Drainage Channels

Frost’s cast iron channels are engineered for heavy-duty applications where strength and longevity are non-negotiable. Manufactured from high-grade cast iron, these channels deliver outstanding compressive strength and resistance to deformation. Their smooth internal profiles help maintain fast, uninterrupted water flow while minimising debris accumulation.

These channels are suitable for surface drainage in commercial forecourts, service yards, car parks, industrial floors and loading bays where repeated vehicle movement demands exceptional impact resistance. Their durability ensures extended service life and reduced maintenance cycles, making them cost-effective over the long term.

Ductile Iron Gratings & Covers

Frost Drainage offers a wide variety of ductile iron gratings, slotted covers and manhole lids that meet EN124 load class standards. Ductile iron provides enhanced tensile strength and flexibility compared to traditional grey cast iron, allowing it to absorb impact without cracking. Surface textures improve slip resistance in wet or icy conditions, supporting public safety in high-traffic areas.

Load class options range from A15 for pedestrian zones to F900 for extreme heavy-duty environments, including ports, logistics centres and airport facilities. Reinforced frames and secure locking mechanisms keep the gratings in place under stress, preventing displacement and reducing maintenance risks.

Gully Grates

Frost gully grates are designed to deliver high water capture efficiency while handling the structural pressures of vehicles, forklifts and heavy equipment. Hinged options allow easy access for cleaning and maintenance, while robust ductile iron ensures long-term durability. These grates are commonly installed in car parks, loading bays, estate roads and commercial courtyards.
