Black Iron Wire
Wanlida black iron wire is made with 6.5mm thick steel rod, through wire drawing, cooling, annealing and galvanizing processes. With the features of great flexibility, high durability and consistent color, the black iron wire is suitable for use as tie wire or baling wire. High quality and economically priced, it is extensively used in the construction, mining, chemical, and other industries.
