External Drainage Channel ALCADRAIN AVZ102-R103, 100 mm, plastic frame, galvanized grate B125

ALCADRAIN AVZ102-R103 is an external drainage channel with a 100 mm internal width, featuring a lightweight plastic frame and a galvanized B125-rated grate. It is designed for surface water collection and conveyance in areas with pedestrian traffic and light vehicular loads. The combination of a corrosion-resistant galvanized grate and a durable plastic channel body delivers a practical solution for driveway edges, sidewalks, terraces and garden drainage installations.

Advantages

The plastic frame reduces overall weight and simplifies handling and installation while maintaining dimensional stability. The galvanized grate offers corrosion resistance and a B125 load rating suitable for pedestrian areas and light-traffic driveways. The channel’s 100 mm internal width provides adequate flow capacity for typical residential and landscape drainage needs. Modular design allows linear installations and easy access for maintenance.

How to use

Position the drainage channels along the intended runoff path, ensuring a consistent slope toward the outlet or collection point. Secure the plastic frames within the prepared trench and connect sections end-to-end for continuous flow. Place and fasten the galvanized grate on top of the frame according to manufacturer alignment features. Backfill around the channel edges with suitable bedding material and compact to provide stable support while avoiding deformation of the channel body.

Usage recommendations

Regularly inspect and clear leaves, sediment and debris from the grate to maintain flow capacity. For installations subject to heavier traffic or concentrated loads, verify load conditions and consider alternative products or additional reinforcement. Ensure proper slope and outlet capacity to prevent standing water.

ALCADRAIN AVZ102-R103 is intended for reliable surface water management in residential and light commercial settings where a galvanized B125 grate and a lightweight plastic frame meet functional and installation requirements.
