Professional-Grade Water Feature Components Atlantic's 316 Stainless Steel Spillways deliver exceptional performance for pond builders, landscape contractors, and water feature enthusiasts. These premium spillways transform ordinary walls into stunning water features while withstanding harsh chlorinated environments that would corrode standard stainless steel. Why 316 Stainless Steel Matters Unlike 304 stainless steel, 316 grade contains molybdenum for superior corrosion resistance against chlorine, salt water, and chemical treatments. This makes these spillways ideal for pools, spas, and treated water features where longevity matters. Installation Benefits The modular 4-inch height design eliminates cutting and fitting issues common with other spillways. Each unit adapts to standard garden wall blocks and supports 80 pounds per linear foot - strong enough for masonry installation without additional lintels or structural support. Maintenance Advantages The non-clogging weir design reduces debris buildup and maintenance requirements in open basin applications. Heavy-gauge construction ensures years of reliable operation even in demanding commercial installations.
