Aluminium Square Hopper Grid 150mm x 150mm

Product Description

Repair or upgrade your drainage access with the Aluminium Square Hopper Grid 150mm x 150mm. This premium grid cover is designed for square hopper inlets and underground drainage points, fitting securely over openings to prevent debris from entering while allowing efficient water flow. Built to match Polypipe’s robust standards, this aluminium grid provides both durability and a clean, professional finish.

This square grid is crafted from high-quality aluminium, combining strength with corrosion resistance. Ideal for locations exposed to general external conditions— patios, back gardens, driveways, or walkways— it offers a strong metal grate surface that withstands real-world wear. The square shape aligns well with paving and architectural features where square hopper inlets are present, giving a flush, aesthetic integration.

With its 150mm × 150mm size, the grid covers standard square hopper openings. The metallic finish helps resist rust and degradation from weather exposure while holding up under load where pedestrian traffic may pass.
