Durable mechanically galvanized powder-driven collated pins built for steel and concrete fastening in corrosive environments — bridges, coastal infrastructure, industrial facilities, and exterior applications. JLHY's 33-year manufacturing expertise includes in-house mechanical galvanizing lines that apply a thick (≥45µm), uniform zinc coating that adheres better than electroplating, providing long-term corrosion resistance equivalent to hot-dip galvanizing in a mechanically applied format.

The collated pin format enables high-speed sequential fastening with powder-actuated tools, dramatically reducing installation labor compared to individual pin driving. Available in smooth, fluted, and knurled shank profiles with domed or flat head options to match your specific application requirements.

JLHY supplies these pins to infrastructure contractors, transportation engineering firms, and construction fastener distributors worldwide. Our 100+ machine production lines and 20,000 m² facility near Tianjin Port ensure we can fulfill large container orders with consistent quality, competitive pricing, and full technical documentation including coating thickness reports, hardness certificates, and compliance documentation for international projects.
