Shouguang Reliable Steel Company

If a steel mill suspends production of two bar production lines for steel pipe supports, it is expected to affect the daily output of threaded steel by about 5000 tons, and the high-speed production line of a steel enterprise will undergo a 13 day maintenance, affecting the output of about 43000 tons. A steel mill conducted a 15 day shutdown and maintenance on its annual production line of 800000 tons of bar steel, affecting the output of rebar by about 30000 tons. One steel mill's bar steel production line underwent a 8-9 day shutdown and maintenance, and did not produce during the Spring Festival, affecting the daily output of rebar by about 1300 tons. February holiday factors+maintenance, coupled with the fact that February itself has fewer working days than other months. Therefore, steel production will not significantly increase in February, but traders will face increased inventory due to winter storage, which will increase sales pressure after the holiday and curb the rise in building materials market prices. From the perspective of regional changes in the supply of building materials in the market, the decline in supply in North China will be higher than in other regions. This year, the "North to South" movement of building materials is strong, fast, and large-scale. This is because the prices of building materials in the southern region are higher than those in other parts of the country, and even higher than those in the northern region. On February 9th, the market price of Φ 20mm third grade rebar in Guangzhou was 4330 yuan/ton, while the price of Φ 20mm third grade rebar in Shenyang and Changchun was 3920-3930 yuan/ton, with a price difference of 400-410 yuan/ton between the two cities. Therefore, a large number of resources from "North Materials Southward" have entered the South China region, especially the Guangzhou region. "North Materials" has more resources, and the inventory of building materials market has increased significantly. The inventory of Hangzhou construction steel market in East China has also increased significantly, with a fast growth rate. From the trend of changes in construction steel inventory across the country, the inventory growth rate and expansion in South China and East China are faster and greater than those in North China and Northeast China. The regional changes in the supply of building materials in the market will directly affect the market trend in March. From the perspective of construction steel market demand, during the Spring Festival, construction projects were basically stopped. Some projects were closed in advance due to the rainy and snowy weather before the festival and the Spring Festival was later than previous years, so the project was required to start as soon as possible after the festival. According to the traditional practice, the full construction of the project after the festival was generally resumed after Yuanxiao (Filled round balls made of glutinous rice-flour for Lantern Festival), and migrant workers returned to the city. However, this year's Yuanxiao (Filled round balls made of glutinous rice-flour for Lantern Festival) Festival was in the first ten days of March. Therefore, the demand for construction steel market was still difficult to release significantly in the last ten days of February and the beginning of March, and it would take about one month to one and a half months for construction projects to stagnate their demand for steel. So, in mid to late March, the demand for building materials in the market will gradually be released.

On February 2nd, PB powder transactions in Tangshan area were 528 yuan/wet ton, Tianjin area were 560 yuan/wet ton, Shandong area were 528 yuan/wet ton, and 62% Mysteel imported ore price index was 73.75 US dollars/dry ton. Mysteel statistics show that from January 22nd to 28th, the total shipment of iron ore from Australia and Brazil was 23.734 million tons, an increase of 2.686 million tons compared to the previous month. Among them, the total amount of iron ore shipped from Australia was 16.798 million tons, an increase of 1.759 million tons compared to the previous period. 14.383 million tons were sent to China, an increase of 1.793 million tons compared to the previous period; The total shipment of iron ore from Brazil was 6.936 million tons, an increase of 927000 tons compared to the previous period. In terms of variety, the main increase is in the production of high-grade powder ore and block ore. The shipment volume of Mack powder in high-grade powder ore has increased to a historical high level, while the PB block in block ore has increased significantly. The Newman block has not changed much, and the shipment volume of medium and low-grade powder ore has fallen from last week's high to the same period last year. According to Mysteel's statistics, the total arrival volume of the six major ports in northern China from January 22nd to 28th was 7.715 million tons, a decrease of 1.648 million tons compared to the previous period. In the next week, there will be a significant increase in the volume of Australian shipments to China, and at the same time, the six northern ports are forecasted to have a significant increase in port volume this week, so the port volume may increase this week. It is expected that the arrival of Australian mines in February will decrease by 3 million tons compared to the previous month, and the arrival of Brazilian mines will decrease by 1 million tons compared to the previous month. On February 2nd, Mysteel reported that the iron ore inventory in 45 ports across the country was 151.43 million tons, a decrease of 390000 tons compared to the previous week. From a regional perspective, there are still many arrivals from major ports in North China recently. Due to the impact of pre holiday steel plant inventory, the volume of port clearance has slightly increased, and port inventory has also slightly increased; The port congestion in the Yangtze River region is still relatively severe, with a slight decrease in port clearance and overall inventory showing a slight decline. There are still two weeks left until the Spring Festival, and most steel mills have already completed stocking up. Some steel mills will gradually replenish their inventory.

Among the irregular components, medium thick plates, high-quality bars, and profiles are the main types of steel consumed in the construction machinery industry,? =””normalbackground-color:ffffff，? =After the 2008 subprime mortgage crisis, China implemented a "4 trillion yuan" economic stimulus plan, which led to a significant increase in sales of construction machinery such as excavators from 2009 to 2013. The replacement cycle of domestic excavators is usually 8 years, which means that the period from 2018 to 2020 is the peak period for replacing existing excavator equipment. The growth in demand for construction machinery updates in 2018 is expected to maintain the industry's prosperity. normalbackground-color:ffffff，? =””normalbackground-color:ffffff，? =Passenger car sales are expected to grow at a slow pace in 2018. At present, China's automobile industry has entered a mature stage, with a rapid increase in car ownership, overcapacity, and a rapid decline in production and sales growth. In the future, China's automobile production and sales will maintain a low growth state for a long time. normalbackground-color:ffffff，? =””normalbackground-color:ffffff，? =The demand for infrastructure steel is expected to significantly decrease. Normal background color: ffffff, what,? =””normalbackground-color:ffffff，? =It is expected that the growth rate of domestic infrastructure investment will significantly decline to 12% in 2018. This is mainly due to two reasons: firstly, the strengthening of supervision over local government financing behavior, and secondly, the increase in bond yields leading to higher financing costs for local governments. normalbackground-color:ffffff，? =””normalbackground-color:ffffff，? =Is the steel export situation in 2018 similar to this year's normal background color: ffffff,? =””normalbackground-color:ffffff，? =This year, the clearance rate of steel production capacity is relatively fast, and the supply of steel remains tight. Domestic steel prices have risen rapidly, and the price difference between domestic and foreign steel has been rapidly widened since November 2016. The competitiveness of domestic steel exports has sharply declined. At the same time, due to the shortage and good prices of domestic steel, the enthusiasm of Chinese steel enterprises to export steel has also significantly decreased. Under the influence of the above two factors, China's steel exports from January to November 2017 have significantly decreased by more than 30% year-on-year, and it is expected that the annual export volume will decrease by 32.5 million tons compared to 2016.

Specifically, for steel structures, the Xiben Steel Index will operate in the range of 3780-3860 yuan next week. 1. Market Review 1. Xiben Steel Index 2. Price Situation of Shanghai Threaded Steel This week, the overall price of building materials in Shanghai rose. As of May 22, the Xiben Index was reported at 3830, up 80% from last weekend; During the same period, the representative specifications of high-quality grade III threaded steel in Shanghai increased by 80 yuan/ton compared to last weekend; The representative specification of high-quality snail in Shanghai has increased by 70 yuan/ton compared to last weekend. Last weekend, boosted by the news of increased production restrictions by northern steel mills, steel billets in Tangshan, Hebei rose sharply, driving up the overall spot prices; Entering this week, Shencheng Building Materials has continuously raised prices, with a significant cumulative increase. However, after the prices have risen, the market's fear of heights has grown, and demand has significantly weakened; In the second half of the week, as the futures market fluctuated downward, spot prices slightly fell. In this period, the guiding prices of leading steel mills in East China have generally increased, with an increase of 50-80 yuan/ton, indicating that with the general rise in raw material prices, steel mills have a strong willingness to raise prices. At the same time, the social inventory of building materials continued to decline this week, providing some short-term support for steel prices. Overall, Shencheng Building Materials will experience fluctuating operations next week. 3. According to data monitored by the Xiben Shinkansen in the national market, the overall trend of building materials in China has been upward this week, with significant increases in the northern and southern regions. Specifically, the performance of various regions is as follows: Beijing market: spot prices in Beijing market have risen significantly this week, with an overall increase of 150 yuan/ton compared to last weekend. Currently, Hebei Iron and Steel's HRB400E Ø 12 Ø 14mm small thread costs 3700-3720 yuan/ton, HRB400E Ø 16mm thread costs around 3670 yuan/ton, and HRB400E Ø 18-22mm large thread costs 3610-3630 yuan/ton; The quotation for HRB400 Ø 8-10mm spiral screw is 3750-3780 yuan/ton. Last weekend, stimulated by the news of stricter production restrictions by Tangshan steel mills during the Two Sessions, Tangshan steel billets surged by 70 yuan/ton, guiding domestic steel companies to collectively raise prices. In the first half of this week, with the significant strengthening of the futures market and the push up of steel mill guidance prices, the bullish sentiment in the market was stimulated, and local spot prices continued to rise, with high trading volume. In the second half of the week, futures contracts fluctuated at a high level, market sentiment began to cool down, prices stabilized at a high level, and transactions gradually slowed down.

The emergence of various windows undoubtedly continues to optimize the entire world of architecture. How does the concrete production of windows improve all existing building tools? In the specific production process of the construction industry, all the industrial production opportunities that people can seize are always unexpected in real life. In the specific history of building material production and development, almost all fun stainless steel louvers can no longer truly compare to zinc steel louvers. Engaging in different types of louver production projects, almost all of us need to study different louver production design work seriously, which is a very important fact for most people. For the specific design of various types of louvers, many people engaged in louver design believe that the existing choices are highly meaningful. Until now, the various designs of blinds used for play have been constantly influencing people of all kinds..

In fact, in light steel structure buildings, due to the extensive use of roof skylights, the number of windows on the walls can be reduced, which can effectively ensure building lighting without damaging the lines of the wall panels. In addition, there are also differences in the lines of the wall panels in terms of panel shape, which is another important factor affecting the shape of the lines. 3. Architectural color: The use of various colored metal profiled steel plates makes light steel structure buildings appear rich and colorful, especially the bold use of jumping colors and cool tones, which can give people a refreshing feeling that is clearly different from traditional buildings. The expression of color includes two parts, one is the color expression of roofs and wall panels, and the other is the color expression of decorative parts such as edge finishing and flashing. Domestic enterprises often choose white, blue, and red colors, and rarely choose brown, black, or multiple color combinations. This is not only due to the trend of aesthetic consciousness among social groups, but also due to the monotonous color of domestically produced boards, as well as the aesthetic issues of design engineers and buildings, and the subjective and arbitrary issues of property owners. 4. Architectural changes: Small scale buildings designed by foreign companies often draw on the architectural style of small-scale concrete buildings, including the decoration and expression methods of concrete buildings, in pursuit of architectural style. Although small in scale, the diversity of changes makes small-scale buildings exhibit a dynamic architectural style. However, domestic enterprises, which are mostly square buildings, do lack changes..

There are four grades of steel plates for bridge structures: Q235GJ, Q235GJZ, Q345GJ, and Q345GJZ (GB/T714-2000). There are three grades of steel for bridge structures: Q235q, Q345q, Q370q, and Q420q, with quality grades of C, D, and E. What are the classification codes for hot-rolled H-beams and sectional T-beams? Wide flange H-beam - HW (W stands for Wide in English)? H-shaped steel with a middle flange - HM (where M is the Middle prefix)? Narrow flange H-beam - HN (N stands for Narrow in English)? Wide winged T-shaped steel - TW (W stands for Wide in English)? T-section steel with split middle flange - TM (where M is the Middle prefix)? Narrow flange section T-section steel - TN (N is Narrow in English) hot-rolled H-beam and partial T-section steel specification marking method Height H x Width B x Web thickness t1 x Wing thickness t2, for example: HW100 x 100 x 6 x 8; TN125 × 60 × 6 × 8..

In this situation, the shipment volume of steel enterprises has begun to decline slightly, and the inventory has steadily increased. The driving force of raw materials and futures has reduced the period of decline. Recently, the trend has mainly been a slight decline, and even in the short term, there is no ability to continue to move up, and it will continue to fluctuate. According to monitoring, bulls are continuously reducing their positions, which is bearish on the market and has dampened the enthusiasm of the spot market. The market for raw materials such as ore and coke has also been relatively weak in recent days, and their driving effect on finished products is at a relatively low level. In this situation, the price of finished products is naturally dragged down or suppressed to a certain extent. In the short term, the supply-demand contradiction in the building materials market still exists, but due to the high market price and reduced downstream demand, inventory may continue to increase slightly, which will have a certain negative impact on building materials prices. However, the short-term overall reduction and adjustment of futures positions may not receive strong support or fluctuate. So, overall, due to the downstream weakening and the need for supply and demand adjustment, the prices of building materials and steel may experience a slight correction in the short term..

Construction waste is piled up and buried near cities, trapped in a "garbage siege" situation, not only occupying land, but also containing various harmful chemicals, severely eroding the surface and polluting groundwater sources, posing a great threat to the human living environment.
