2. From the recent market perspective, domestically, infrastructure development is still weak at this stage, and local government special bond issuance is slow. In the future, with the decline of PPI and the economic downturn, infrastructure investment is expected to accelerate. , and the delayed release of funds to alleviate the previously expected problem may most likely be reflected in mid-November. Abroad, last Wednesday, Federal Reserve Chairman Powell denied considering raising interest rates, taking the lead in sending a dovish signal, while the Bank of England also unexpectedly decided to keep interest rates unchanged.

1. Market Current Situation

From a macro perspective, domestic steel prices fell sharply in 2013, and the prices of Chinese steel products will fall sharply, because there has always been the problem of overcapacity, and mainly Raw material iron ore prices also fell. China's slowing economic growth is curbing the country's demand for steel and iron ore, dragging prices of both commodities to multi-month lows and putting expansion plans of global iron ore producers at risk. The trend is not expected to change in the coming months because there is too much capacity and industry consolidation is too slow; at the same time, the iron ore oversupply problem has also increased, indicating that its price will continue to fall.

2. Classification methods

There are two commonly used classification methods for rebar: one is classification based on geometric shape, which is classified or divided according to the cross-sectional shape of the transverse ribs and the spacing between the ribs. For example, in the British Standard (BS4449), rebar is divided into Type I and Type II. This classification method mainly reflects the gripping performance of rebar. The second is based on performance classification (grade). For example, in my country's current implementation standards, rebar is (GB1499.2-2007) wire rod is 1499.1-2008). Rebar is divided into grades according to strength level (yield point/tensile strength). 3 grades; in the Japanese Industrial Standard (JI SG3112), rebar is divided into 5 categories according to comprehensive performance; in the British Standard (BS4461), several grades of rebar performance testing are also specified. In addition, rebar can also be classified according to its use, such as ordinary steel bars for reinforced concrete and heat-treated steel bars for prestressed reinforced concrete.
