What Is GI Corrugated Roofing Sheet? GI (Galvanized Iron) Corrugated Roof Sheet is a roofing material made of galvanized iron or steel that forms a series of parallel ridges and grooves, creating a corrugated pattern. This pattern not only adds strength to the roofing sheet, but also allows for effective drainage, making it suitable for use in areas with high rainfall. The galvanizing process involves applying a layer of zinc to iron or steel sheets to protect them from corrosion and rust, thereby increasing their durability and longevity. GI corrugated roofing sheets are commonly used in residential, commercial and industrial construction projects due to their affordability, durability and corrosion resistance. These roofing sheets are available in different thicknesses, widths and lengths to meet different roofing needs and are often installed with overlapping edges to ensure a watertight seal. They are commonly used in roofing applications such as warehouses, agricultural buildings, and residences, providing protection from harsh weather while also being visually appealing.

From the foreign factors, overseas debt and banking crisis has not yet appeared to ease the situation, the recession is expected to enhance, which will bring impact of the global steel financial system. At the same time, the U.S. interest rate hikes at the top, the emergence of interest rate cuts are expected, the global deflation is also expected to greatly increase, which will accelerate the economic environment downward, the pressure on the manufacturing industry and industry. Overseas financial recession transmission to the entity recession will continue, the risk of a substantial increase. At the same time, geopolitical conflict game, the divergence between economies will be intensified. In addition, the U.S. debt ceiling, the continued decline in the price of power coal, domestic deflationary concerns, the disappearance of the demographic dividend, the risk of municipal bonds, the extension of the accounts receivable period, the decline in the double coke there is still room (negative feedback is not over), etc., are in the mood to suppress the black commodity prices.
State-run large steel mills hot coil to galvanized steel average cost of about 750-800 yuan/ton, so galvanized - hot coil spread during this period is also the normal level. 2021-2023, the peak of the plating heat spread in May 2021, more than 1,300 yuan / ton. 2021, the plating heat spread of 700-1,300 yuan/ton; 2022 spread fluctuations in the range of 655-1079 yuan/ton. 2023, the plating heat spread of 700-1300 yuan/ton; 2022 spread fluctuations in the range of 655-1,079 yuan/ton. 2023, the plating heat spread is still down. 1079 yuan/ton. 2023 January-April, the heat-plating spread is 650-900 yuan/ton, which belongs to the normal spread level. After entering May, the plating heat spread continued to climb, reaching a maximum of 1,020 yuan/ton. As of June 12, the spread in 958 yuan / ton. For the year, this spread already belongs to the high level, this kind of non-normal spread with the market demand continues to be falsified, will return to the market normal level, from the point of view of varieties of spreads, spreads still have a certain amount of repair space, the probability is that the price of galvanized to the hot rolled to see the same.
Profit is an important indicator of the production enthusiasm of private steel mills. In recent years, more and more steel mills to join the production of galvanized coil, and galvanized coil competition has become increasingly fierce. The processing cost of hot coil to private galvanized is 500-600 yuan/tonne or less. From Mysteel data show that in 2021, the average monthly price of private galvanized in the north and the north of the mainstream hot coil settlement price difference of 645-921 yuan/ton, basically profitable every month, and even part of the monthly profit can reach 300 yuan/ton; 2022 spread of 510-863 yuan/ton, of which there are five months less than 600 yuan/ton; 2023 January-May, the spread of 547-668 yuan/ton, and only the price difference of 500-600 yuan / ton, and only the price difference of 500-600 yuan/ton. 668 yuan/tonne, and only May is higher than 600 yuan/tonne. From the data can be clearly seen, the current private galvanized coil production and utilization is extremely small, and even part of the early loss-making state. But from the point of view of capacity utilization, the current capacity utilization rate is still maintained at a relatively high level, such as if the production did not decline to some extent, the low profits of private steel mills will continue to be maintained.
From the galvanized three mainstream market regional spreads, 2023 June three mainstream market regional spreads are inverted. Taking the price of Shougang as an example, as of June 12, the prices in Shanghai, Tianjin and Guangzhou were RMB 4,940/tonne, RMB 4,980/tonne and RMB 4,900/tonne respectively. Shanghai-Tianjin galvanized spread upside down 40 yuan / ton, while Guangzhou galvanized price is lower than Shanghai 40 yuan/ton. Shanghai as the main inflow of galvanized coil, the price is more forward-looking. And in the current inventory situation, in the short term the regional spread anomaly will be maintained. Overall, Tianjin galvanized prices still have a certain downward space, but according to the current situation, the regional spread repair to the normal level, but also need time to wait.
Throughout the 2021-2023 galvanized coil turnover, the least amount of turnover during the Spring Festival. Demand is the litmus test of the market price, the demand for good or bad can also be intuitively reflected in the daily turnover. 2021, in addition to the Chinese New Year before and after the month, the rest of the month galvanized coil monthly average turnover of more than 20,000 tons. 2022, the industry's demand continues to shrink, the national turnover of galvanized coil in March more than 20,000 tons, the rest of the month fluctuations in the 15-18,000 tons, most of the month to keep in the 16,000 tons or less. Into 2023, we can clearly see that the volume of galvanized coil volume remains at a low level. Specific data, galvanized average daily turnover in May was 17,026 tons, down 14.75% from March. If the turnover in 2022 is attributed to the epidemic, and 2023 after the optimization of anti-epidemic measures, the turnover in January-June can clearly reflect the real demand situation in the market. In the process of market price decline, terminal purchasing is more and more cautious, and purchasing always needs several times of deliberation. Therefore, in the face of poor market turnover and falling market prices, the confidence of market merchants has been seriously undermined.
General Administration of Customs data show that in April 2023, China's total exports of the galvanized sheet (strip) totaled 1,099,100 tons, a month-on-month increase of 14.83%, a year-on-year increase of 68.85%; in January-April 2023, China's total exports of galvanized sheet (strip) totaled 3,589,900 tons, a year-on-year increase of 31.10%.1-4 months in 2023, galvanized sheet and strip export performance was relatively Bright, especially in April, when galvanized sheet and strip exports increased by more than 68% year-on-year.
In the current downstream demand is difficult to have a significant improvement in the basis of price changes in raw material co
sts, directly affecting the lower end of the price of galvanized sheet coil. From the varieties of spreads, the galvanized sheet metal coil in June rose significantly less than the upstream raw material hot rolls, but the spread is still maintained at a relatively high level, short-term spreads or will continue to maintain. And from the mindset, the recent market mentality due to stronger futures have some improvement, but the actual demand is still to be confirmed by reality. The current supply of galvanized coil remains at a relatively high level and will continue to be maintained in the short term. From the export side, the export data of galvanized sheet and strips in 2023 performed more brightly and also reduced pressure for domestic trade. Later on, we need to pay attention to the recovery speed of demand, the production change of steel mills, and the digestion speed of inventory. The overall galvanized sheet coil will also follow the raw material hot coil prices and fluctuations, it is difficult to get out of their own independent market in the short term.
1)Market: During the National Day, coated sheet coil prices in all regions of the country showed a stable trend, most of the country's market galvanized and color-coated sheet coil prices remain consistent with the pre-holiday period, a small portion of the market traders have pressure on inventories, there is a dark drop in the case of walking away from the goods. The current market purchasing sentiment is poor, for the post-holiday market trend is that the possibility of a big rise or fall are not likely, or will remain a stable trend.
2) Supply: state-run steel mills during the holiday period of normal production, maintenance of the situation in the early days, the current end of the order situation is better, so the production situation is normal. It is reported that in the northern state-run steel mills in October, the proportion of general material placement is still low, and the settlement price is high, traders' ordering enthusiasm is not strong. The private producers have about 4-5 days of maintenance time during the holiday season before the holiday has been stocked with spot inventory, so the impact on shipments is not great.
3) Inventory: from the feedback of the market inventory situation, after the end of this year's holiday market inventory increase is not obvious, mainly because the pre-holiday social inventory has been at a low level, coupled with the regional market to the local steel mills resources are mainly foreign resources shipments less, so the inventory although there is an increase, but there will not be too much pressure, I believe that the increase in post-holiday inventory will not produce a large impact on prices, compared with previous years, the price will not have a large impact on the market. A larger impact, compared with previous years will still show a low inventory trend.
Through the in-depth analysis of the historical trend of Chinese steel prices and the factors affecting them, we can see that steel prices are affected by raw material prices, policies and regulations, the international market, and other factors. In the future, with the industrial restructuring and changes in the international market environment, steel prices will face new challenges and opportunities. Therefore, the relevant industries and investors need to pay close attention to market dynamics and make corresponding strategic adjustments to cope with the changing steel market.
As a pillar product of basic industry, steel has a wide range of applications in construction, transportation, manufacturing and other fields. Its price fluctuations directly affect the cost and profitability of related industries. Part I: The impact of raw material prices
Iron ore is one of the main raw materials of steel, and its price fluctuations directly affect the production cost of steel. The supply and demand relationship in the international iron ore market, changes in production and adjustments in international trade policies will have an important impact on iron ore prices.
Coke is an essential fuel and reducing agent in the steelmaking process, and its price fluctuations will directly affect the cost of steelmaking. Factors such as Coke's production capacity, raw material prices, and production costs will affect its price.
Alloying elements have a vital impact on the characteristics and performance of steel, and the price fluctuations of alloy raw materials will directly affect the production cost of special steel.
The second part: the impact of policy regulation on steel prices
The Chinese government guides the development of the steel industry through macro-control policies, including capacity adjustment, environmental protection requirements and other policies, the adjustment of these policies will directly affect the supply and price of steel.
Changes in international trade policy will directly affect the steel export market and prices, especially for steel anti-dumping policies and trade dispute resolution.
Changes in the global economic situation will have a direct impact on the demand for steel, economic recession, steel demand declines, and prices are suppressed; in economic growth, steel demand rises, and prices may rise.
Global steel economic situation:
With the development of the global economy and booming international trade, the steel industry plays an extremely important role in the global economy. The following are the main features of the global steel economic situation:
Globally, there is an overcapacity in steel, which has led to intense market competition and downward pressure on prices. Especially in some emerging economies, the steel industry has been expanding its capacity too fast, leading to an imbalance between supply and demand.
With the rise of trade protectionism, many countries have adopted a series of anti-dumping policies to restrict and impose high tariffs on imported steel. This has affected the free flow of global steel trade to a certain extent.
The steel industry has carried out continuous technological innovation and industrial upgrading on a global scale to improve production efficiency, reduce environmental pollution, and lower costs. The application of new steel materials and production processes continues to drive the development of the steel industry.
The steel industry is under pressure from environmental regulations and public opinion to adopt more environmentally friendly and sustainable production methods. Energy saving, emission reduction, and resource recycling have become an inevitable trend in the development of the industry.
Geopolitical tensions, international trade disputes and other factors will also have an impact on the global steel market, for example, the adjustment of tariff policies and changes in the international trade system may have a direct impact on the steel industry.
Overall, the global steel economic situation is full of challenges and opportunities. While coping with the problems of overcapacity and environmental protection pressure, the steel industry is expected to realize sustainable development through technological upgrading and innovative development and make positive contributions to the stability and development of the global economy.
The supply and demand situation in the international market is also an important factor affecting steel prices. Prices in the international market tend to be low when there is global overcapacity, while prices may rise when supply is tight.
International steel market supply and demand situation:
The supply situation in the international steel market is influenced by a number of factors:
Capacity levels: There are a large number of steel producers globally and their capacity levels have a direct impact on the ability to supply the steel market. Some countries have large steel industries, such as China, India and Russia, and their capacity has a significant impact on global supply.
Technology and Efficiency: Steel companies have different levels of technology and production efficiency, which directly affects their supply capacity. Companies with advanced technology are able to produce steel in a more efficient manner, thus gaining a competitive advantage in the market.
Raw material supply: The steel industry has an extremely high demand for raw materials, especially iron ore and coke. The stability of the supply of raw materials directly determines the stability of steel production.
Glob to the growth of demand for steel market.
International Trade Policy: Changes in trade policy will affect the international trade flow of steel, supply and demand.
Environmental regulations and sustainable development: Strengthening of environmental regulations and increasing awareness of sustainable development will bring adjustments to the high energy consumption and high pollution steel industry, which may affect
Suzhou coated market is still mainly stable, the National Day merchants are all closed, manufacturers continue to production, shutdown maintenance situation is relatively small. It is understood that the galvanized coil Zhangjiagang Wanda 1.0mm is priced of 4530 yuan/ton, and color coated coil Suzhou crown King 0.47mm is priced of 5000 yuan/ton. Steel Policy, October 1,
