Atlantic Water Gardens 12" Stainless Steel Spillway - 316 Steel
AT-SS12-316
316 Grade for Lasting Pond Wall Elegance
The Atlantic Water Gardens 12-inch stainless steel spillway in 316-grade steel delivers a clean, modern cascade of water over a polished lip for pond walls, retaining walls, and formal water features. The 316 grade alloy provides superior corrosion resistance versus standard 304 stainless — critical in the presence of pond water chemistry, fertiliser run-off, and the chloride levels common near Canadian coastal and urban environments.
316 Stainless — The Corrosion-Resistant Choice
Grade 316 stainless adds molybdenum to the alloy composition, which dramatically improves resistance to pitting corrosion from chlorides and pond chemistry. Over years of outdoor exposure, 304-grade spillways can develop surface rust staining that mars the appearance of a formal water feature. The 316-grade construction of this spillway maintains its brushed finish season after season without protective coatings. The 12-inch width produces a graceful curtain of water ideal for smaller pond walls and accent features.

How to Install
Mount the spillway on the pond wall at the desired height using the included hardware. Connect a 1.5-inch supply line from your pump (sized at 1,200 GPH or less for best sheet-flow effect). Use a pump vault or basin below the spillway to catch returning water. For a uniform water sheet, ensure the spillway is mounted perfectly level — even a 2 mm variance in level causes the water sheet to favour one side.
Ideal for formal pond walls, modern garden features, and contemporary outdoor living spaces across Canada.
