Inspection Standard of Wire Rod

Inspection Standard of Wire Rod

Wire rod is also called wire, usually refers to a small diameter round steel plate. On the site common diameter 6, 8, 10, 12 mm, in the majority of low carbon steel, generally not used for reinforced concrete structure of the main reinforcement, mostly used for reinforcing steel sleeve, and small diameter for brick structure in the “brick reinforcement”. There are many varieties of wire rod, carbon steel wire rod in the low carbon steel wire commonly known as soft wire, medium and high carbon steel wire commonly known as hard wire. Wire rod is mainly used as drawing blank, but also directly used as building materials and machine parts.
