BG-FILCOTEN® trench drain pro G:

Trench drains with heavy to ultra-heavy duty cast-iron edge rails 4”, 6”, 8”, 12″

heavyweight when it comes to performance:


Because BG-FILCOTEN® pro G trench drain can handle a high load capacity, it is especially suitable for installation in industrial areas such as distribution centers, factories and warehouses. With its sleek good looks it can easily be used in public places such as railway stations, and pedestrian or residential areas.

Channel geometry / surfacing

The flat inner surface of BG-FILCOTEN® channels are highly crafted making each channel smooth in order to minimize surface friction. This attention to detail achieves the best possible flow characteristics and a superior self-cleaning effect. The textured outer surface ensures perfect cohesion with the concrete bed.

With our BG-FILCOTEN® pro G channel, you don’t have to compromise on quality or durability.

It’s stable yet lightweight, and can be adapted to site conditions. BG-FILCOTEN® pro G trench drain is equipped with cast iron rails, and is available up to class F 900 (acc. to EN1433).

High traffic bolted iron grip

The bar grating is rated up to cl. E 600 kN, and the slotted grating is rated to cl. F 900 kN. Additional gratings may be available depending on the load requirements. All locking systems are supplied as a kit, and are simple and easy to change.

Unique “fiX“ snap-On locking system

The intelligent fiX connection enables a secure and stable four-point easy install, quick release locking system for the grate and channel.

Anti-slide lugs prevent longitudinal grate shifting

Two anti-sliding lugs interlock the grating against the railing preventing any longitudinal shifting creating an additional layer of safety.

Perfect installation

Anchoring ribs ensure a secure bond and anchoring of the channel with the surrounding concrete bed.

Innovative production technology

The innovative BG-FILCOTEN® production and molding technology allows for flat sides, making flush installations against buildings easy and attractive. Our advanced design technology has included support and anchoring ribs, creating structurally strong installation.

Stability thanks to the FEM analysis

The FEM analysis is a computer-assisted process which simulates load demands. The more accurate the known effect of force, the easier it is to choose the optimal design solution.
