    摘要： Nails (14) suitable for outdoor use, such as roofing nails, are formed from carbon steel wire (10) pre-coated with a metallic layer (12), which has corrosion-resistant properties, such as a zinc layer applied by pre-galvanizing the wire. Each nail (14) is formed with a shank (18) and with a head (16). The metallic layer is discontinuous in a region (22) on the head (16) of each nail (14). The nails are collated by means of collating wires (24) welded to the shanks of the nails (14). The collated nails are coiled. The coiled nails are cleaned in a cleaning bath, such as 1,1,1,trichloroethane. The cleaned nails are coated with a polymeric layer, which covers the region (22) on the head (16) of each nail (14) where the metallic layer is discontinuous, thus restoring the corrosion-resistant properties of the nails (14).

    摘要翻译： 适用于户外使用的钉子（14），例如屋顶指甲，由预先涂覆有金属层（12）的碳钢丝（10）形成，该金属层具有耐腐蚀性，例如通过预先涂覆的锌层， 镀锌丝。 每个钉（14）形成有柄（18）和头部（16）。 每个指甲（14）的头部（16）上的区域（22）中的金属层是不连续的。 钉子通过对齐焊接在钉子（14）的柄部上的线（24）进行整理。 整理的指甲盘绕。 盘绕的指甲在清洁浴中清洁，如1,1,1，三氯乙烷。 清洁的指甲涂覆有聚合物层，其覆盖金属层不连续的每个指甲（14）的头部（16）上的区域（22），从而恢复指甲（14）的耐腐蚀性质。
