Marine environments are brutal on iron. Salt spray and tidal exposure will corrode carbon steel nails within months. JLHY's stainless steel nails in A2 (304) and A4 (316) grades are the only appropriate choice for coastal projects, marine structures, and any application near the ocean where long-term corrosion resistance is essential.

A2 provides good atmospheric corrosion resistance for coastal residential applications. A4 with its molybdenum addition delivers superior performance right at the shoreline — marine pilings, seawalls, boat docks. Stainless nails are also essential for pressure-treated timber, where copper compounds corrode carbon steel rapidly.

Available in smooth shank, ring shank, and finish nail profiles in gauges from 2.0mm to 5.0mm and lengths from 25mm to 150mm. All JLHY stainless nails are passivated. Contact our team for grade recommendations for your specific coastal environment.
