Speaking of rebar Bian Xiao, I believe many people don't know much about it. Rebar is also called hot rolled ribbed bar. The grade of common hot rolled steel bars is generally composed of HRB minimum value and grade yield point. So Bian Xiao believes that many people will ask what H, R and B mean. Hz refers to hot rolling, R refers to ribbed steel bar, and B refers to steel bar. The initials of these three words constitute HRB. Let's take a look at the rebar quotation and market situation in Bian Xiao.

I. Current market situation

From a macro point of view, the domestic steel price of 20 13 has fallen sharply, and the domestic steel price will fall sharply, because there has been a problem of overcapacity, and the price of iron ore, the main raw material, has also fallen. China's slowing economic growth is curbing the country's demand for steel and iron ore, which has brought the prices of these two commodities down to a few months low and put the expansion plans of global iron ore producers at risk. It is expected that the trend will not change in the next few months, because there is too much production capacity and the speed of industry integration is too slow; At the same time, the problem of oversupply of iron ore has also increased, indicating that its price will continue to fall. 20 13 coal coke steel futures fell again, while the stock market was stable, and the differentiation between steel futures and stock market trends intensified. The reason is the intensification of the contradiction between supply and demand in the steel industry chain itself.

Second, the classification method

There are two common classification methods of steel bars: one is to classify according to the geometric shape of steel bars, and the other is to classify or classify according to the cross-sectional shape of transverse bars and the spacing between bars. For example, steel bars are classified into Type I and Type II in British Standard (BS4449). This classification mainly reflects the grip performance of steel bars. Second, according to the performance classification (grading), such as China's current implementation standards, rebar is (G? B 1499.2-2007), rebar is divided into three grades according to strength grade (yield point/tensile strength); Japanese industrial standard (Ji? SG3 1 12)？ Rebar can be divided into five categories according to comprehensive; British Standard (BS446 1) also stipulates the performance test of steel bars. Several grades. In addition, steel bars can also be classified according to their uses, such as ordinary steel bars and prestressed steel bars for reinforced concrete. Heat-treated steel bars for concrete and the like.

Third, the application and quotation

Steel bars are widely used in civil engineering construction such as houses, bridges and roads. From highways, railways, bridges, culverts, tunnels, flood control, dams and other public facilities to the foundations, beams, columns, walls and slabs of buildings, steel bars are indispensable structural materials. With the deepening of urbanization in China, there is a strong demand for rebar with the vigorous development of infrastructure construction and real estate. The market price is generally 2520 yuan per ton? (Price source network, for reference only)? .

Many people may ask: Are steel bars really ubiquitous in our lives? Anyone who has slightly observed the things around life will find that steel bars are everywhere. Rebar can also be bought everywhere in the market, which is not used by ordinary families, but only for construction sites. Of course, when we buy it ourselves, as long as we need to buy it as much as possible. Today, the market situation and market conditions of rebar introduced by Bian Xiao are here, hoping to help everyone.
