Industrial-strength 1-1/2" collated concrete nails designed for powder-actuated fastening of steel and concrete in commercial and infrastructure construction. JLHY's 33 years of precision nail manufacturing produces hardened collated concrete pins using controlled heat treatment processes that achieve the exact Rockwell hardness required (typically 55-60 HRC) for penetrating concrete without bending. The collated strip format enables rapid sequential driving with powder-actuated tools — a critical productivity feature on high-volume steel fabrication and concrete anchoring job sites. Available with smooth, fluted, or spiral shank profiles to suit different substrate conditions and holding requirements.

JLHY supplies collated concrete nails to structural steel contractors, concrete forming companies, and construction fastener distributors globally. Our production capacity of 20,000 tons annually ensures we can fulfill container-load orders within standard lead times. We offer bulk packaging, custom branding for distributors, and full technical documentation including hardness test reports and coating certifications.
