How much is a ton of four cold-drawn wires?

Cold drawing is also called cold drawing, and there are also cold-drawn threads, which are common steel bars. The raw material is wire, that is, steel bar. Because steel bar is a commodity, the price changes with the change of the market, and the price is unstable. Generally, the price of steel bar plus processing fee is the price of cold drawing. The processing fee of cold-drawn wire in Yunnan Pinyi Steelmaking Plant is per ton of 400 yuan. If it is adjusted to a certain length of straight rod and 300 yuan is added as required, the price may be lower. Still have to ask in person.
