Duplex-head nails define
Double-Headed Design: Duplex nails have two distinct heads, one above the other, which allows for easy removal after use. The larger head is used to drive into objects, and the smaller head remains exposed for removal.
High Strength: Typically made from high-strength low carbon steel, duplex nails offer high tensile and bending strength, making the duplex nails capable of withstanding significant weight and pressure.
Surface Treatment: Duplex nails can have a bright, polished finish for indoor use or the galvanized finish for outdoor use, with the latter offering rust resistance.
