Five Chinese sheet metal fabricators highlighted for 2026

A new review spotlights five Chinese sheet metal fabrication companies and the supply-chain roles they fill, from heavy custom fabrication to tooling-led precision stamping. The list is aimed at buyers in energy storage, power generation, machinery and other industrial sectors that need to match part size, process scope and export readiness to a supplier’s published capability.

Why it matters: - China remains a major source of custom metal parts, welded assemblies and fabricated components for global equipment makers. - For buyers, the key issue is not just price. It is whether a supplier can handle the required part size, weight, tolerances and process mix without rework. - The review is designed to help importers, OEM procurement teams, distributors and engineering firms narrow supplier lists faster.

What happened: - Xiamen Openex Mechanical Technology Ltd led a five-company review of China’s sheet metal fabrication sector. - The review also named Xiangxin Technology Co., Ltd., Jiangsu Tongrun Equipment Technology Co., Ltd., Suzhou Dongshan Precision Manufacturing Co., Ltd. and Shenzhen Silver Basis Technology Co., Ltd. - The companies were presented by registered name, headquarters location and publicly disclosed business scope. - The review did not use revenue, output, market share or financial data.

The details: - Xiamen Openex Mechanical Technology Ltd was established in 2009 and operates two manufacturing premises, one near Xiamen Port and one near Shanghai Port. - Xiamen Openex says it has a 30,000 square metre facility, about 200 staff, including 35 engineers, and annual production capacity of 20,000 tons. - Published processes at Xiamen Openex include laser cutting, bending, punching, stamping, welding, machining, assembling, roll forming, casting, forging, galvanizing and powder coating. - Xiamen Openex says its maximum overhead crane tonnage is over 250 tons, its maximum bending machine length is over 18 metres, and its maximum CNC machine tool travel reaches 50 m x 8 m x 7 m. - The company’s disclosed products include energy storage system cabinets, ultra-long formed steel box sections, equipment enclosures, telescopic booms, steel chassis for coil handling, prefabricated pipelines, energy storage steel frames and steel conveyor frames. - Xiamen Openex says export business accounts for 80% of total sales. - The company lists Europe, the USA, Australia, New Zealand, Japan, Singapore, South America and the Middle East as major markets. - Xiamen Openex says it has delivered pressure vessels, machine frames, steel chassis and steel structures to the USA, Canada, Japan, the UK, European countries and Australia. - Xiamen Openex says it produces 80% to 90% of the metal parts, components and assemblies it exports, with partner companies supplying the rest. - The company says casting, forging, hot-dip galvanizing and some powder coating are handled by partners. - Xiamen Openex says small parts in small quantities are not an efficient order profile for its model. - The company says projects that require only casting, forging or anti-rust finishing are better suited to specialists in those processes. - Xiangxin Technology Co., Ltd. is a Shenzhen Stock Exchange-listed joint-stock company headquartered in Dongguan, Guangdong Province. - Xiangxin Technology’s disclosed business covers precision stamping dies and precision sheet metal structural components, with demand concentrated in automotive and new energy equipment. - Jiangsu Tongrun Equipment Technology Co., Ltd. is a Shenzhen Stock Exchange-listed company registered in Changshu, Jiangsu Province. - Jiangsu Tongrun’s disclosed operations include sheet metal products such as metal tool cabinets and storage cabinets, along with electrical equipment. - Suzhou Dongshan Precision Manufacturing Co., Ltd. is a Shenzhen Stock Exchange-listed precision manufacturing group headquartered in Suzhou, Jiangsu Province. - Suzhou Dongshan’s disclosed business scope spans precision metal components and other precision manufacturing segments. - Shenzhen Silver Basis Technology Co., Ltd. is a Shenzhen Stock Exchange-listed company registered in Shenzhen, Guangdong Province. - Shenzhen Silver Basis’ publicly disclosed operations cover large precision moulds and precision structural components, including applications in automotive and communications equipment. - The review says the five companies are not ranked against one another and makes no comparative performance or capacity claims for companies two through five.

Between the lines: - The companies sit in different parts of China’s metalworking base, so they are not direct substitutes in many sourcing scenarios. - The main divider is envelope and process mix, not simply whether a shop can cut and bend sheet metal. - Heavy forming, machining and handling capacity narrow the field quickly when the part is large or heavy. - Outsourcing matters because casting, forging, galvanizing and coating are often subcontracted, which can shift lead times and quality responsibility. - Export-oriented suppliers may be better prepared for documentation, packaging and shipping requirements than first-time exporters. - The market is moving toward larger fabricated assemblies and off-site prefabrication, which favors suppliers with controlled workshop capacity.

What's next: - Buyers are expected to verify legal entity status, plant locations, in-house versus outsourced processes, maximum envelope, tolerances, drawing formats and quotation readiness before placing orders. - Xiamen Openex says it accepts STEP, IGES, DWG, DXF, PDF and other 2D and 3D formats. - The company says quotations are fastest when both 2D and 3D drawings are provided. - Xiamen Openex does not publish a fixed minimum order quantity, but says large parts in large quantities are preferred and small parts in small quantities are not cost-effective. - Buyers in energy storage, power generation, heavy machinery, mining and oil and gas will continue to select suppliers based on whether the published envelope and order profile match the drawing.

The bottom line: - In China’s sheet metal fabrication sector, the decisive question is not which company is biggest. - It is which supplier can handle the size, weight, process scope and export requirements of the part on the drawing.
