Overcapacity in the five major sectors of aluminum‑plate materials—covering aluminum plates, ceramic‑coated aluminum panels, perforated aluminum sheets, aluminum ceiling grids, high‑strength aluminum panels, engraved aluminum panels, custom‑shaped corrugated panels, and other aluminum‑plate products—has been highlighted in an analysis of overcapacity across these five areas. “From 100 million tons to today’s 800 million tons, it is still being described as overcapacity,” said the deputy secretary-general of the China Iron and Steel Association in an interview with China Investment. By contrast, the association previously reported that China’s steel production capacity had reached 800 million tons at the time, yet the actual effective capacity was only 400 million tons, with another 400 million tons remaining without official state approval.
Overcapacity in the five major sectors of aluminum‑plate materials—covering aluminum plates, ceramic‑coated aluminum panels, perforated aluminum panels, aluminum ceiling grids, high‑strength aluminum sheets, engraved aluminum panels, custom‑shaped corrugated panels, and other aluminum‑plate products—has been highlighted in an analysis of excess capacity across these five areas. “From 100 million tons to today’s 800 million tons, it is still being described as overcapacity,” said the deputy secretary-general of the China Iron and Steel Association in an interview with China Investment. By contrast, the association previously reported that China’s steel production capacity had reached 800 million tons at the time, yet the actual effective capacity was only 400 million tons, with another 400 million tons remaining without official state approval.
Since being designated as suffering from overcapacity in 1999, the steel industry has typically expanded whenever demand rises. Based on demand forecasts, the state has consistently imposed strict planning on capacity expansion in the sector; however, because actual demand has repeatedly exceeded planned capacity, market‑wide capacity has also frequently surpassed official targets. For example, the State Council’s “Plan for Adjusting and Revitalizing the Steel Industry,” issued in 2009, projected China’s crude steel consumption at 430 million tons, yet actual consumption reached 570 million tons. According to estimates by the China Iron and Steel Association, crude steel consumption could climb as high as 680 million tons, while the state‑approved steel production capacity stands at only 400 million tons. This implies that roughly 400 million tons of non‑compliant capacity remains in the market, serving to bridge the supply‑demand gap.
In fact, over the past decade, through meticulous regulatory oversight, China’s steel, cement, and nonferrous metals industries have consistently been classified as “overcapacity” sectors, subject to stringent restrictive policies in areas such as land use, finance, taxation, and project approval.

Let us introduce you to what aluminum tubing is.
Aluminum tubing typically refers to pipes made from aluminum alloys. Aluminum alloys are materials composed of aluminum combined with other metallic elements, characterized by their light weight, high strength, and excellent corrosion resistance, making them widely used across various industries.
Aluminum tubes are mainly classified into the following types.
Classified by precision: ordinary aluminum tubes and precision aluminum tubes; the latter typically undergo secondary processes such as cold drawing and rolling after extrusion.
With the rapid growth of the new‑energy vehicle industry, automotive thermal management systems are confronting entirely new challenges and opportunities. In this field, aluminum tubing, thanks to its superior performance and broad range of applications, has steadily emerged as an unsung leader in thermal management for new‑energy vehicles, providing robust support for enhanced vehicle performance and safe operation.
Production and Manufacturing of Aluminum Tubes
Aluminum tubes are classified into four main types based on their forming process: hot-extruded aluminum tubes (the mainstream), cold-drawn and precision-rolled aluminum tubes, welded aluminum tubes, and impact-extruded pharmaceutical aluminum tubes. Among these, the most widely used in the industry is seamless or split‑die extruded aluminum tubing.
What is the difference between 409 stainless steel and 430 stainless steel?
Compared with ordinary low‑carbon steel, 409 stainless steel sheet exhibits poorer thermal conductivity and lower elongation; consequently, greater deformation forces are required during shearing and bending. For 321 stainless steel sheet, springback during bending is more pronounced than in carbon steel. Moreover, since the elongation of stainless steel sheet is lower than that of carbon steel, the bend radius R of the workpiece should be larger than that for carbon steel during bending operations; otherwise, cracking is likely to occur.
What is the difference between 202 stainless steel and 304 stainless steel?
202 stainless steel and 304 stainless steel are both austenitic stainless steels at their core, non-magnetic, and visually quite similar. However, the key difference lies in their nickel content, which results in significant variations in their mechanical properties and price.
