Cold drawing is a kind of metal cold working. Raw material is wire rod, after shelling, galvanized and other processes produced. Galvanized cold wire drawing is used in building materials more, its detection standard also each is not identical. The strength of cold drawing is higher. So, how to apply the cold drawing of the construction industry?
Because of the high strength of steel, it plays a very important role in the construction. It saves the construction steel in the building materials, and reduces the project cost. It also plays a very important role in the structure of concrete.
Cold drawing is mainly used in the production of hardened low carbon steel wire, with a diameter of 8 mm steel bar to carry out a fixed role, in the development of the construction industry has played a role in promoting the development, the application is more extensive.
The bond anchorage between cold drawing wire and concrete is good. Used in the component, the phenomenon of cracking in the anchorage area of the component and damage caused by wire slippage can be eliminated fundamentally, and the bearing capacity and crack resistance ability of the component end can be improved.
In reinforced concrete structures, the crack width of cold-drawn steel bar is smaller than that of circular steel bar, even than that of hot-rolled steel bar. Therefore, cold drawing is more popular in the construction industry.
