In recent years, the scale of China's construction machinery industry has been growing rapidly. In 2020, the business revenue of the whole industry reached 775.1 billion yuan, up 16% year on year, reaching the highest level in history."Difference" in early July, the construction machinery industry development planning ", "planning" by 2025 China construction machinery industry revenue to reach 900 billion yuan, while the development of construction machinery industry has a good momentum of development, but also faced with new challenges, especially in China is on the road to high quality development,"The 14th five-year Plan" construction machinery industry "steel demand" high-quality transformation will usher in a new development opportunity.

Construction Machinery Industry ushered in "New Power" for Development

In recent ten years, China's construction machinery industry has been developing rapidly. During the "13th Five-Year" period, the industrial scale of China's construction machinery industry reached 775.1 billion yuan, an increase of 69.6% compared with the "12th Five-Year" period. Among them, the total import and export of construction machinery reached 126 billion US dollars, an increase of 4.39% compared with the "12th Five-Year" period, among which the export accumulated 105.9 billion US dollars.Imports totaled US $20.1 billion, down 26.45%.In the 14th Five-year Plan, China will start a new journey to build a modern socialist country in an all-round way. The development of construction machinery industry will be at a new starting point, and an all-round development era will also be opened. Intellectualization, big data, 5G and other new technologies will give new impetus to the development of China's construction machinery industry.

During the 14th Five-year Plan, China's economy will shift from the stage of high-speed growth to the stage of high-quality development, which also puts forward higher requirements for the development of construction machinery industry. The construction machinery industry must carry out quality reform to improve the endogenous growth power, so as to realize the road of high-quality development.During the 14th Five-year Plan period, China's economic development space is huge, the scale of infrastructure construction is still huge, the construction machinery market is still in the rising period, and the stock renewal and new demand are equal.In the face of the new situation and new requirements of China's economic development during the 14th Five-year Plan, the construction machinery industry will carry out six industrial innovation projects: the new high-tech construction machinery innovation pilot project;Engineering machinery intelligent manufacturing Promotion Project;Engineering machinery product reliability improvement project;Construction machinery testing, testing and evaluation digital platform construction project;Construction machinery industry chain strong base development project;Construction machinery industry Internet application platform construction project.At the same time, we will continue to carry out supply-side structural reform, actively base ourselves on the new development stage, fully implement the new development concept, and make new achievements in accelerating the construction of a new development pattern with the domestic big cycle as the main body and the domestic and international cycles mutually reinforcing.

Construction machinery industry "steel demand" ushered in new opportunities

Engineering machinery is one of the important part of equipment industry, generally all conditions of construction engineering, road construction and maintenance, flow type lifting handling operation and various construction projects need necessary for comprehensive mechanized construction engineering machinery and equipment, known as the engineering machinery, mainly used in construction, transportation, national defense construction,Energy industry construction and production, mining and other raw material industry construction and production, agriculture, forestry and water conservancy construction, industrial and civil construction, urban construction, environmental protection and other fields.Construction machinery mainly includes digging machinery, shovel transportation machinery, engineering lifting machinery, industrial vehicles, compaction machinery, piling machinery, concrete machinery, etc., construction machinery as a large steel consumption industry, among which, thick plate accounts for 50%;Tubing (seamless steel and thick pipe), 10%;Bar 13%;Hot-rolled sheet and cold-rolled sheet accounted for 20%;Other steel accounts for about 7%.

With the continuous development of the construction machinery industry, the strength level of the steel is becoming higher and higher, and the construction machinery steel is also developing towards the direction of high strength and high toughness.The development of steel for construction machinery in China started late. After the introduction of foreign construction machinery manufacturing technology in recent 20 or 30 years, the steel for construction machinery in China gradually broke the status of Q235 and Q345 low grade steel.At present, has developed 600, 700, 800, 1000MPa and more than the class of high strength construction machinery steel, 600MPa class construction machinery steel is mainly used for the manufacture of large crane, bulldozer, scraper transport, hydraulic support, etc.700MPa class steel for construction machinery is mainly used for crane boom, large excavator, large hydraulic support, etc. 800MPa class steel for construction machinery is mainly used for bulldozer, construction crane, heavy truck and roller drill, etc. 1000MPa class steel for construction machinery is mainly used for coal mine hydraulic support, wear-resistant parts of construction machinery, etc.

At present, China's construction machinery industry in the core basic parts and components, advanced basic technology, key basic materials and high-end manufacturing equipment and other key areas of the core technology there are obvious deficiencies and short boards, China's construction machinery industry to high-quality development has formed a significant constraint.Although, China's construction machinery steel has made some progress, but the overall level of steel quality is not high, and some high-end steel needs to rely on imports, compared with similar foreign products, in the durability, reliability gap is larger.According to the 14th Five-Year Development Plan of Construction Machinery industry, by 2025, more than 90% of core basic parts and key basic materials will be independently guaranteed, and the industrial innovation development pattern of complete machine traction, foundation support, coordination and interaction will gradually be formed.At the same time, the construction machinery industry should also build a collaborative innovation system covering the industrial chain, accelerate the breakthrough and catch-up of core components and steel technologies for construction machinery, and achieve large-scale substitution of imported high-end steel for construction machinery, so as to enhance the core competitiveness of the construction machinery industry.
