Design and Functionality: Duplex nails are specifically designed for temporary construction projects where quick removal of nails is essential. These nails are commonly used in applications like scaffolding and concrete forming, where structures need to be easily assembled and disassembled.
Smooth, Uncoated Shank: The smooth, uncoated shank of the duplex nail allows it to easily penetrate materials such as wood or concrete, while reducing friction during installation and removal, ensuring a cleaner process.
Double Head Design: Duplex nails feature a unique double head design, which includes one head above the other. This makes the nails easier to pull out after use with a claw hammer or other removal tools, perfect for temporary applications that require quick disassembly.
Прыкладанні
- Temporary Construction: Duplex nails are ideal for temporary construction projects, such as building formwork or temporary structures, where they provide a secure hold but can be removed with minimal effort when the project is complete.
- Scaffolding: These nails are widely used in scaffolding to temporarily secure platforms and frames during construction. Their easy removal is essential for quickly disassembling scaffolding once the work is finished.
- Concrete Forming: In concrete forming, duplex nails hold the formwork in place until the concrete is poured and set. Once the concrete hardens, the nails can be easily extracted, making the forming process faster and more efficient.
- Other Temporary Applications: Duplex nails are also used in other short-term construction applications, such as temporary framing, securing supports, or assembling mock-ups, where quick removal is necessary after the work is done.

What Are Duplex Nails Used For?
Duplex nails, also known as double-headed nails, are a staple in construction and carpentry due to their unique design. Featuring two heads along the shank, these nails are engineered for temporary fastening or applications requiring easy disassembly. Their versatility makes them ideal for scaffolding, concrete formwork, and projects where adjustments are frequent. When durability and reliability matter, Hebei Minmetals delivers premium duplex nails designed to meet rigorous industrial standards.
Duplex Nails for Concrete
When working with concrete, fastener integrity is critical. Duplex nails excel in securing wooden formwork to concrete structures, ensuring stability during curing. Their double-head design allows for secure anchoring while enabling effortless removal once the concrete sets. Key features to prioritize include:
Corrosion Resistance: Opt for hot-dip galvanized or stainless steel nails to withstand moisture and alkaline reactions in concrete.
Shank Strength: Ribbed or twisted shanks enhance grip in dense materials.
Hebei Minmetals offers duplex nails with anti-rust coatings and hardened steel construction, ensuring longevity even in harsh environments. Their products comply with ASTM A641 and ISO 1461 standards, making them a trusted choice for contractors worldwide.
Duplex Nails for Nail Gun
For efficiency in high-volume projects, duplex nails compatible with nail guns are indispensable. These nails streamline tasks like framing, roofing, and temporary installations. When selecting nail gun-compatible duplex nails, consider:
Collation Type: Wire-welded or plastic-strip collation for smooth feeding.
Size Compatibility: Match nail length (1.5"–3") and gauge to your tool’s specifications.
Double-Headed Nails for Wood
Double-headed nails, also known as duplex nails, are specially designed for temporary wood construction projects. These nails have two heads: the lower head is driven into the wood, while the upper head remains exposed for easy removal. This makes them ideal for tasks like building concrete forms, temporary bracing, or scaffolding. They provide strong holding power but can be quickly pulled out without damaging the wood. Typically made of steel, double-headed nails come in various sizes such as 6d, 8d, and 16d. Finishes include bright and galvanized coatings to resist rust in outdoor or damp environments.
Why Choose Hebei Minmetals?
