Building collapses and residential elevator accidents caused by disasters continue to occur. At the same time, steel bars are widely used in various fields, such as houses, bridges, railways, roads, tunnels, etc., as skeleton materials for concrete structures. However, there are no mandatory standards for the production of these steels. For a long time, manufacturers have produced only based on the lower limits of the recommended standards.
'A survey said nearly 40% of the construction steel standards in rural areas of several provinces in China are not eligible. 'The head of the China Steel Bar Standardization Committee told reporters at China Business News,' the previous standards were not mandatory, and now the country requires steel to meet higher standards.
The reporter learned that six types of steel production related to the national economy and people's livelihood will meet mandatory standards in the era.
On July 5, Zhang Haideng, deputy director of the Raw Materials Industry Department of the Ministry of Industry and Information Technology, said in the 'Six Key Products of the Mandatory National Standards Promotion Conference on the Promotion of Mandatory National Standards of Thunder Steel Plates and Wires': 'Mandatory National Standards are related to people's lives, national security and ecological security and the safety of life and the safety of life. The cost.'
The reporter learned that elevator ropes also need to meet standards before being sold on the market.
1% profit life and death line
In 2024, the National Administration of Supervision, together with the Ministry of Industry and Information Technology and seven other departments, released the 'Action Plan for Improving the Update of Traction Equipment and Replacement of Consumer Products with Standards', implemented new standards reforms, and included six national standards, including elevator wires and a list of standards such as ribbed steel and hot steel steel steel bars, which are important.
Zhang Haiden said: 'Now it has changed from a recommended national standard to a mandatory national standard, and the Ministry of Industry and Information Technology has organized the National Steel Standardization Technical Committee to carry out revisions. The six national standards involve buildings, elevators, ropes, rock roads, mines and other fields, and more commanding standards. 'A person-oriented' safety concept. '
Recently, the State Administration of Laws and Regulations (National Standardization Administration) issued GB 1499.1-2024 'Steel for Reinforced Concrete Part 1: Ordinary Round Steel Rods for Hot Rolls', GB 1499.2-2024 'Steel for Reinforced Steel, Concrete Part 2: Steel for Reinforced Steel, Steel for Reinforced Steel,' GB 1378-88-248-248-2024 'Elevator Wire Rope', GB 26722-2024 'Ropeways' and GB 33955-2024 'My Wire Rope'
Experts involved in the development of standards told China Business News reporters: 'When landslides and earthquakes encounter, our houses collapse on a large scale, and even explode. We believe that in addition to strengthening management, some measures must be taken to improve production levels and safety levels for people from standard levels.'
Previously, some steel standards involving construction were recommended and there was no legally mandatory nature, so companies could flexibly handle production standards.
The reporter learned that the implementation deviation of the previously approved recommendation standards is plus or 3%. 'To reduce costs, everyone will always choose to subtract 3%, and they will not choose to add 3%. The gap between positive and negative is 6%, so now the range has been further tightened and narrowed, which provides a guarantee for safe production. I think the driving effect of safety assurance is obvious. 'The above expert.
'Since every percentage point increase in product standards may be the life and death of steel costs, some small and medium-sized enterprises are producing according to the minimum limits of recommended standards.
The expert also revealed to reporters: 'In the process of standard formulation, the proposed implementation bias and minus 1% of the industry and information technology leaders have sparked heated discussions.'
Due to the bad real estate market, some rebar manufacturers are already on the line between life and death.
In the future, increasing product profits is to improve product quality, improve customer stickiness and improve product performance to ensure company profits, not just reduce costs.
Increase the diameter of the elevator rope
Zhang Longqiang, secretary of the Party Committee and chairman of the Institute of Metallurgical Industry Information Standards, told China Business News reporter: 'The steel industry is an important basic raw material industry in our country, and has played an important role in supporting the development of the national economy and has played an important role in supporting the development of the national economy. This time it is a national mandatory standard, and this time it involves steel rods and steel rod products, which are important steel products.
He introduced that by 2023, the production of steel rods in our country will reach 226 million tons, accounting for 22.1% of crude oil production. Steel rod products not only have a large content, but also have a wide range, and are related to the national economy and people's livelihoods. Electric wire ropes are basic industrial materials in national economic construction and are widely used in important fields such as coal, cableway, elevator, petroleum, chemical industry, construction, aviation and shipbuilding. By the end of 2023, there will be more than 200 wire rope production companies with production of about 3 million tons.
In recent years, elevator waterfalls have occurred from time to time.
He said: 'One of them, my ceiling rope, elevator wire rope and cableway wire rope are important representative products of wire rope. Due to the particularity and expansion of the application scenario, they play a key role in ensuring the smooth operation of engineering equipment and individuals.
Currently, the number of elevators in China has exceeded 10 million, with the annual demand for elevator ropes being about 300,000 tons (240,000 tons added, and 60,000 tons maintained and replaced). It has the largest market in the world and the largest elevator rope manufacturing base.
It is understood that in 2021, the state government targeting market regulations once conducted random inspections of wire ropes, and the unqualified interest rate was 10.2%. This time, wire rope products produced by 135 enterprises (autonomous regions and municipalities) were randomly inspected, and 19 batches of products were found to be unqualified.
Ren Cuiying, deputy secretary-general of the Wire Rope Standardization Committee, told reporters that the newly released mandatory standards add three new wire rope structures, including 6×24MFC-FC and 6×37m-FC, for elevator ropes. The upper limit of suspension rope diameter has expanded from 22mm to 25mm, and the diameter deviation category of steel core rope has increased.
Driver replaces old equipment with new equipment
In March this year, the State Council issued the 'Action Plan for Promoting Large-scale Equipment Updates and Consumer Products Replacement', which clearly proposes guidance and orderly improvements in compliance with standards and accelerates the formulation and revision of standards in environmental protection and safety combined with the actual development of the industry.
The Ministry of Industry and Information Technology also hopes to implement new standards that will actively promote the update and technological transformation of old equipment, such as production equipment, consumption equipment, and power transmission and distribution equipment, and continuously improve the technical equipment, digitalization and greenness of enterprises.
Zhang Haideng said: 'In the early stage, the Ministry of Industry and Information Technology released the implementation plan for 'Promoting the Update of Equipment in the Industrial Field', organized local government reporting projects, and recommended that the first batch of projects be provided to financial institutions to financial institutions, and that the company's projects will continue to be recommended. Large-scale equipment renewal and consumer goods replacement measures, and a series of fiscal and tax support policies were introduced. Steel companies should fully seize the policy 'opportunity' and continue to improve quality, improve variety and create brands in order to provide more competitive and high-quality products that meet consumer needs to improve quality, improve variety and create brands. It is understood that the Ministry of Industry and Information Technology and the Development and Reform Commission of the Development and Reform Commission, the Ministry of Finance and other relevant departments have successively issued 'guidance' guidance and guidance to accelerate the transformation and upgrading and upgrading of traditional manufacturing industries. The implementation plan is to promote equipment restarts in the industrial sector. In terms of equipment updates, the Ministry of Industry and Information Technology noted: 'Focus on key industries, adhere to market-oriented promotional and standardized leadership, implement advanced equipment and software integration updates and upgrades, and eliminate a batch of inefficient and old equipment.'
