As a basic industry of national economy, iron and steel industry is an important symbol to measure the comprehensive national strength and the degree of industrialization of a country. It is one of the most hardcore manufacturing industries. During the decade from 2011 to 2020, the annual growth rate of domestic manufacturing added value and crude steel output was 7.9% and 5.1%, respectively, which supported the high-quality development of China's manufacturing industry.
"From the development characteristics of China's steel industry, Chinese steel has made the world a better place, mainly reflected in two aspects: on the one hand, it provides important infrastructure materials and functional materials for the improvement of people's quality of life; On the other hand, it is leading the green revolution of the world's steel, implementing the world's most stringent environmental emission standards, creating a global low-carbon development model for the steel industry, and actively practicing low-carbon smelting technologies such as hydrogen metallurgy." Chief engineer li xinchuang metallurgy industry planning institute in the recently held "2021 (12) the development of Chinese steel BBS" that since 2000, the planning institute of metallurgy industry sustainable development in view of the low carbon industry "hot coke difficult problem for special research, fully involved in the steel industry in recent years a series of major field of low carbon policy, standards and cutting-edge technology to track work. At present, entrusted by the relevant ministries and commissions, the steel industry is carrying out a carbon peak and carbon reduction action plan research, the preparation of the "steel industry carbon peak and carbon reduction action plan".
We will accelerate the building of a new pattern of double-cycle development
In 2020, the domestic steel market demand is strong, the super-large internal circulation market provides a strong support for the development of the steel industry, steel production and operation to maintain a high and stable operation situation.
Li Xinchuang told China Economic Herald that the steel industry should accelerate the construction of a new development pattern from the following five aspects: First, to form a new balance between supply and demand. During the 14th Five-Year Plan period, we will continue to focus on supply-side structural reform and development. At the same time, we need to appropriately adjust policies and create new demand, so as to achieve a higher level and higher quality balance between supply and demand in line with the goal of reaching a carbon peak and being carbon neutral. Second, we will promote new technological progress. Strengthen the dominant position of innovation, vigorously promote scientific and technological innovation, expand the socialized channels of innovation input, build various forms of scientific and technological financial cooperation platforms, attract more social capital to participate in the innovation and development of the steel industry, and stimulate the innovation vitality of the whole industry. Third, we will forge a new industrial landscape. We should accelerate the pace of merger and reorganization, build an industrial structure featuring division of labor, cooperation, effective competition and common development, build superior enterprise groups at different levels, and cultivate leading enterprises with global influence, regional appeal and professional influence. Fourth, build a secure supply chain. We will unswervingly implement the internationalization strategy, accelerate the establishment of a long-term, stable and diversified iron ore supply guarantee system, and realize the security and stability of resource supply. Fifth, we need to build a prosperous ecosystem. Promote the integrated development of steel industry, upstream and downstream industries and supporting service industries, and create a healthy, stable, orderly and prosperous steel ecosystem; At the same time, we need to build global cooperation on production capacity.

Pressed corrugated steel sheet (roofing sheet) refers to the steel sheet formed by cold pressing or cold rolling. The steel sheet is made of coloured steel sheet, galvanized steel sheet, stainless steel sheet, aluminium sheet, anticorrosive steel sheet or other thin steel sheet. The profiled steel sheet has the characteristics of light weight, high strength, low price, good seismic performance, fast construction and beautiful appearance.The corrugated metal is a good building material, mainly used for guardrail, floor and other buildings, such as airport terminal, railway station, stadium, concert hall, grand theatre, etc. According to different application requirements, the profiled steel sheet can be pressed into a wave type, a T type, a V type, a rib type and the like. Main Features 1.Rich color:Beautiful shape, rich color, strong decorative, flexible combination, can express different architectural styles; 2.Light weight:Light weight (6-10 kg/m_) high strength (yield strength 250-550 MPa), good skin stiffness, good anti seismic performance of waterproofing agent. 3.Safe and convenient:Construction and installation is convenient, reducing installation and transportation workload, and shortening construction period. 4.Environmental protection:Recyclable and popularized application of profiled steel sheet to meet the sustainable development policy of the national economy.Read more
Galvalume Steel Coil is a kind of Alloy-Coated Steel Sheet widely used in building materials, household appliances,automobiles, environment, machinery, ships and many other fields. The surface coating of galvalume steel sheet is composed of 55% aluminium, 43.5% zinc and a small amount of other elements. 1. Heat reflectivity: Aluminum-coated galvanized steel sheet has a high thermal reflectivity, which is twice as high as galvanized steel sheet. It is often used as insulation material. 2. Heat resistance: Aluminum-zinc alloy steel sheet has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. 3. Corrosion resistance: The corrosion resistance of aluminized and galvanized steel coils is mainly due to the protective function of aluminium and aluminium. When zinc is abraded, aluminium forms a dense layer of alumina,which prevents further corrosion of corrosion-resistant substances. 4. Economy: Because the density of 55% Al-Zn is smaller than that of Zn, the area of galvanized steel sheet is more than 3% larger than that of galvanized steel sheet under the same weight and thickness of gold plating. 5. Easy to paint: Aluminum-coated galvanized sheet and paint have excellent adhesion and can be painted without pretreatment and weathering treatment. 6. Aluminum-galvanized steel sheet has a silver-white gorgeous surface.Read more
