Round Artium Grate (HDPE)

The Round Atrium Grate (HDPE) is engineered for superior outdoor drainage performance in areas subject to leaves, mulch, debris, and intermittent heavy flow. This elevated “atrium” style grate is molded from structural high-density polyethylene (HDPE) with UV inhibitors to resist sun damage and weathering. Designed for use with 9″ or 12″ round catch-basins, it provides a raised dome profile that allows water entry while keeping float-able debris at bay. Ideal for landscaped areas, natural beds, window wells, patios, and other outdoor settings.

Key Features

• HDPE (high-density polyethylene) construction for long service life and chemical/impact resistance.
• UV-inhibitor additives included — helps protect against sun damage and material degradation outdoors.
• Designed to fit 9″ or 12″ round catch basins for compatibility with common drainage systems.
• Raised/domed grate profile (“atrium” style) helps prevent debris and mulch from blocking the grate while allowing free water flow.
• Ideal for installation in residential and light commercial outdoor spaces such as landscaped beds, patios, natural areas, window wells.
• Corrosion-resistant, weather-resilient material – reduces maintenance and replacement costs.
