In this period, the price of construction steel in various markets across the country has declined across the country. Among them, the Northeast, Northwest, and North China markets plummeted, leading steel mills to follow up; East, Central, South, and Southwest demand fell, and prices fell chaotically. The steel index fell sharply this week, and the cost index fell slightly, indicating that the profit margin of steel mills has been compressed; this week, the rebar futures broke down, which brought a drag on the spot market expectations.
In terms of futures, most of the major black contracts went down this week: iron ore oscillated adjustment, coke dived at a high level, hot rolls fell sharply, and the thread broke back. Among them, the hot coil 2201 contract closed at 5,322 yuan on Friday night trading, down 305 yuan/ton from last Friday night trading; the rebar RB2201 contract closed at 4889 yuan/ton on Friday night trading, down 512 yuan from last Friday night trading. Yuan/ton; Judging from the trend of the whole week, the raw material end (especially coke) has taken the initiative to fall, and the finished product end (especially the thread) has dropped significantly.
Looking back on this issue, the news is lack of boost, the raw material market has adjusted, and the threaded spot has fallen sharply. What changes have occurred in the current industry? What is the trend of steel prices in the later period? Let's take a look at the relevant inventory data monitored by the information, and then analyze it in detail.
According to information inventory monitoring data, as of October 21, the total rebar inventory in Shanghai stock market was 235,700 tons, a decrease of 44,100 tons from last week, a decrease of 15.76%. Inventories in Shanghai have fallen for the ninth consecutive week; current inventories Compared with the same period of the previous year (380,200 tons on October 22), the volume decreased by 150,500 tons, a decrease of 38.97%. This week's inventory decline was mainly due to the limited replenishment of foreign resources and the negative stockpiling of traders to reduce the risk of inventory reduction.
In this issue, the Shanghai stock market line spiral week terminal purchase volume monitored by the information was 16,800 tons, a decrease of 9.19% from last week; this week’s terminal purchase volume decreased from the previous week, mainly due to weak terminal demand, coupled with the collapse of market prices, and construction sites delayed To order. Judging from historical data, the current terminal purchase volume is lower than the normal level, and it is expected that it will be difficult to increase the volume in the later period.
The steel index fell sharply in this issue, and the market price plummeted: Monday, it fell slightly; Tuesday, it continued to drop; Wednesday, it stopped falling and rose slightly; Thursday, it fell in the intraday market; Friday, the chaos fell. The current situation of the Shanghai market is: social inventories are still declining, and terminal demand is declining month-on-month; there is not much pressure on supply, and merchants are more willing to ship. The market is currently in a state of "panic", and it is expected that the steel index will likely fall but not rise next week.
Pre-Galvanizing Pipe is widely used in petroleum ,chemical industry, construction, shipbuilding, communications, electricity and underground gas pipelines and many other fields.
Pre-Galvanizing Pipe is galvanizing, Zinc layer is an electroplating layer, and zinc layer is separately stratified with the steel tube matrix.
Pre-galvanized steel pipe is the treatment of steel pipe before galvanizing: degreasing treatment, derusting treatment, phosphating treatment, drying treatment.
Hot dipped galvanized steel pipe is in manufacturing process using steel pipes of removed rust dipped into zinc liquid of 500℃ temperatures, and making steel surface attached zinc layer so as to achieve the purpose of anti-corrosion.
Hot galvanizing process specially suitable for kinds of strong-acid, alkali fog and other strong corrosive conditions. This kinds of fastener used a lot in outside of steel tower contribution.
Black steel pipes have a variety of use. Thanks to their strength and needs for little maintenance. They tend to be used for transporting gas and water to rural areas and urban areas or for conduits that protect electrical wiring and deliver high pressure steam and air. In addition, black steel pipes are also used in oil and petroleum industries for piping large quantities of oil through remote areas.
Other uses of black steel pipes include gas distribution inside and outside homes, water wells and sewage systems. However, black steel pipes are never used for transporting potable water due to the fact that they tend to corrode in water and mineral of the pipe will dissolve into the water and clog the line as well.

Seamless pipes are manufactured by extruding the metal to the desired length. Thus, they do not have any joint in its cross-section throughout its length. seamless pipes are marketed on an outdated myth that it does not have flaws but that welded has an inherent flaw throughout the length of each tube, as stated above. Intuitively this concept is easily accepted by purchasers and designers with limited experience with the various products.
Steel porp refers to the use of steel pipe, H-shaped steel, angle steel, etc. to enhance the stability of the engineering structure. Generally, it is an inclined connecting member, and the most common are herringbone and cross shapes. Steel supports are widely used in subways and foundation pits. Because the steel support can be recycled and reused, it is economical and environmentally friendly.
Steel coil is sheet metal supplied in coil form. Depending on the production method, such coil is classified as hot-rolled, cold-rolled, galvanised or polymer-coated . Steel coil is used across industry, the main consumers being the construction and machine-building sectors.
