There are two main factors that affect the rise: first, demand is gradually recovering, and small and medium-sized traders have not stocked up during the Spring Festival, resulting in a centralized release of demand in the short term and centralized procurement to push prices higher; The regional air quality has reached the standard, and more stringent environmental protection inspections have been adopted, resulting in some steel companies restricting or even suspending production. The first influencing factor is what the author predicted before the festival. There are very few small and medium-sized traders in stock this winter, and the goods are basically concentrated in the hands of the first-level agents of large steel mills and small and medium-sized steel mills. Due to the difficulty in sales of small steel mills, this year The phenomenon of production reduction or even suspension of production in winter is relatively common, which makes the pressure on spot inventory in local markets after the holiday this year is not great. The intermediate traders and traders who deliver to the terminal have no goods in their hands. After the construction site and project start, they will start from the first-level agent. Purchasing by merchants and steel mills gradually drove up prices. After the prices showed signs of rising, an atmosphere of rushing goods was formed, which made the rate of price rise gradually accelerated. The impact of the second factor is slightly beyond the author's expectations, and I did not expect such a large impact. There are expectations in the market that the new environmental protection law will be implemented, but the State Council’s tough stance on pollution control at the Two Sessions exceeded market expectations, especially in late March as the International Olympic Bid Committee will come to Beijing and Zhangjiakou to inspect the 2022 Winter Olympics As for the preparations for the bid, the environmental protection department strictly inspected at this point, stationed in major areas such as Chengde, Zhangjiakou, Tangshan, etc., to check the sewage discharge situation of steel plants, which directly ignited the market sentiment and led to a continuous sharp rise in steel prices across the country, especially in North China.
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.
