HighQuality Duplex Head Nails Factory and Suppliers in China
Duplex Head Nails, historically known as scaffold nails, are high-performance fastening solutions engineered specifically for the rigorous demands of the construction industry. Featuring a unique double-headed architecture, these nails are meticulously designed to provide maximum stability while ensuring effortless extraction, making them an indispensable asset for any temporary installation project.
The ingenious design allows workers to drive the nail until the lower head is flush with the surface, leaving the upper head protruding. This configuration enables rapid removal using a tie rod or the claw of a hammer once the temporary structure is no longer required. By blending industrial-strength holding power with unmatched convenience, Duplex nails significantly reduce labor time and material waste during the dismantling process.

Frequently Asked Questions
Unlike standard nails, duplex nails feature two heads. The bottom head secures the material, while the top head remains exposed, allowing the nail to be pulled out easily without damaging the surrounding structure.
They are primarily used in temporary construction such as scaffolding, concrete pouring formwork, temporary braces, and theatrical set design where rapid disassembly is critical.
Yes, they are engineered to provide the same structural holding power and resistance to bending as standard common nails, ensuring the safety and stability of temporary installations.
Selection depends on the thickness of the material and the required load. We offer a full range from 1-3/4" (6D) for light bracing up to 4" (30D) for heavy-duty structural formwork.
Absolutely. Because they are designed for easy extraction without bending the shank, duplex nails are highly reusable, reducing material costs over the long term.
We offer a comprehensive variety of gauges and lengths. For specific custom requirements beyond our standard table, please contact our technical team for a tailored solution.
