Why SS316 for Outdoor Glass Fencing
Grade 316 stainless is often called "marine grade" because it holds up much better than SS304 against chloride environments — coastal air, saltwater pools, and heavily chlorinated water. For pool surrounds and beachside installs, SS316 hardware is the sensible choice to prevent tea-staining, pitting, and rust bleed.

- M12 threaded rod (any length)
