CA 2042811

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

Clous pour utilisation à l'extérieur, par exemple clous pour toitures, fabriqués à partir d'un fil d'acier au carbone recouvert d'une première couche métallique antirouille, par exemple une couche de zinc, appliquée en prégalvanisant le fil. Chaque clou comporte une tige et une tête. La couche métallique est discontinue dans une région de la tête de chaque clou. Les clous sont assemblés au moyen de fils soudés à la tige des clous. Les clous sont ensuite formés en spirale, nettoyés dans un bain composé par exemple de 1,1 trichloroéthane, et ensuite recouverts d'une couche de polymère appliquée sur la région de la tête de chaque clou où la couche métallique est discontinue, ce qui confère aux clous des propriétés anticorrosives.
