This year’s GDP is the worst data since the outbreak of the US financial crisis in 2014, and this may be the largest asset bubble in the past decade. At the recent high-level economic forum, some experts judged that the Chinese economy will successfully bottom out in the next two years. This is a very important decision-making judgment, that we are in the channel of bottoming out in the next two years.
　　 China now has everything in surplus. Let's look at the manufacturing industry first. Almost all the industry's largest workshops are in China. There are already several steel structure workshops of 200,000 m2 and 300,000 m2. From home appliances, mobile phones, to steel structures, our production capacity is very surplus, this is a big and unjust business. Speaking of Made in China, there are actually two terms, one is cost and the other is scale. Made in China is a great victory of cost + scale. Today, costs and scale have emerged one after another.
So, how to make a living from sacrificing environmental protection? The author believes that Chongqing steel structure enterprises must pay attention to the improvement of their core competitiveness, gradually increase scientific and technological innovation, lead the transformation of manufacturing methods through intelligent manufacturing, and implement steel structure construction projects. Collaborative design, large-scale personalized customization, precise supply chain management, full life cycle management, etc., learn the German steel structure industry's spirit of paying attention to quality, and have a rigorous attitude to every detail. Germany enjoys a high reputation in the fields of precision metal processing and machinery manufacturing, and it is very valuable for Chinese companies studying in large manufacturing countries.
　　 In addition to the advanced automatic CNC equipment for steel structure processing, its steel products have different characteristics from China. First, the steel structures they process are mainly hot-rolled H-shaped steel, angle steel, channel steel, square steel, and other profiles. Welded BHs are few, welded cross structures and box-shaped structures are less, and hot-rolled profiles have economical cross sections. A large amount of pre-cutting, assembly and welding are reduced, so generally no straight board blanking equipment is needed in the workshop, and there are few BH assembly welding production lines, which realizes green manufacturing. Second, the connection of the German steel structure products on-site nodes are all high-strength bolts, which are welded at the construction site without fire. Not only greatly reduces the workload on site, but also very convenient for packing and transportation. However, in order to ensure the piercing rate, the machining accuracy of bolt holes is required to be high. The proportion of profiles used in China's steel structure is low, and the site nodes are connected by bolt welding, which increases the workload of assembly welding of the factory manufacturing body, resulting in an increase in overall costs. Third, the German steel structure industry attaches great importance to the organic combination of structural design, detailed design and production management, and workshop processing equipment automation. Through the research and development of management software, it continuously improves the greenness of steel structure manufacturing and provides value-added services to customers.
　　 The history of the rise and fall of world powers has repeatedly proven that without a strong manufacturing industry, there can be no prosperity of nations and nations. Creating an internationally competitive manufacturing industry is the only way for my country to improve its overall national strength, ensure national security, and build a world power.
