Galvanized steel spiral anchor pins with clear plastic protective sleeves.
Used to secure Hay Covers. 5/16 in galvanized steel wire.
Galvanized steel performs best in Soil solutions with a pH in the range of 5.5 to 12. pHs between 3 and 5.5 (acidic) or 12 and 13.5 (basic) are corrosive to galvanized steel, but the galvanized coating will still give corrosion protection to bare steel, although the protection will only last for a few years.
