JLHY supplies reliable fastening solutions designed for temporary construction, concrete formwork, scaffolding, and reusable wood structures. Double head nails—also known as duplex nails—are engineered for easy installation and fast removal, making them ideal for projects where disassembly and material reuse are required.

JLHY double head nails are produced using high-quality low-carbon steel (Q195 / Q235), offering excellent toughness, controlled hardness, and resistance to bending during driving. The dual-head design features a lower head that secures materials firmly and an upper head that remains exposed, allowing workers to quickly pull the nail out without damaging the surface. This structure significantly improves job-site efficiency and reduces labor time.

Our manufacturing range includes smooth shank double head nails with precise diameter control to ensure consistent holding strength and easy extraction. Available sizes typically range from 2 inches to 4 inches, with custom lengths and wire diameters available upon request to meet regional standards or specific application needs.

JLHY offers multiple surface finish options, including bright finish for indoor and short-term use and hot-dip galvanized for enhanced corrosion resistance in outdoor or high-moisture environments. Galvanized coatings are applied evenly to improve durability and extend service life during repeated use.

In addition to stable product quality, JLHY provides OEM and private label services for global B2B customers such as importers, wholesalers, distributors, and construction material brands. OEM solutions include customized specifications, branded packaging, bulk cartons, palletized shipments, and export-ready labeling. Each production batch undergoes strict quality inspection, covering material verification, dimensional accuracy, head alignment, and surface finish evaluation.

By partnering with JLHY for double head nails OEM manufacturing, you gain a dependable factory focused on technical consistency, scalable production capacity, cost efficiency, and long-term B2B cooperation, helping you serve professional construction markets with confidence.
