I modified the hardware slightly by using Simpson Strong-Tie galvanized fasteners instead of concrete wedge anchors for ease of installation and strength. I also used silicone to prevent galvanic corrosion between the stainless steel and galvanized metals especially in the highly corrosive environment near Florida’s Intracoastal Waterway. Hopefully that will decrease against degradation and extend the lifespan. I wish the vendor would provide the grade of stainless steel. I’m only using them for the stair landing not the main deck level and suspect it’s 304 stainless steel or low grade.
