Abstract: The production of micro-alloved and hot-rolled,residual heat treated and cold-rolled reinforced steel bars by foreign Steelmakers is surveyed.A comparison is made between the three grades in terms of their advantages and disadvantages as well as their application fields.
Owing to the economic recovery currently occuring in the major industrialized nations,the demand of international reinforced bars is booming and the price is upping,which gives domestic suppliers great opportunities of promoting exports.The V-bearing 3^# grade steel bar is an idea type of reinforced bar,which will gradually substitute the 2^# grade in the domestic market and can adapt to the international construction market.
