Shandong Liaocheng Jiuyang Steel Pipe Manufacturing Co., Ltd., a well - established professional steel enterprise since 2012 with a registered capital of 50 million yuan, is a leading provider of square tubes. As a company that seamlessly integrates domestic and international trade and industry, it has extensive experience in the production and supply of square tubes, serving a global clientele. Square tubes are a versatile and essential product in the steel industry. They are characterized by their rectangular cross - section with four equal sides, which provides excellent structural stability and load - bearing capacity. These properties make square tubes suitable for a wide array of applications, from construction and manufacturing to transportation and infrastructure development. The company's square tube production process is highly sophisticated. It starts with the selection of high - quality raw materials, ensuring that the steel used meets strict quality standards. Advanced manufacturing techniques, such as hot - rolling and cold - forming, are employed to shape the steel into square tubes. Hot - rolled square tubes are known for their strength and durability, making them ideal for heavy - duty applications. Cold - formed square tubes, on the other hand, offer greater dimensional accuracy and a smoother surface finish, suitable for applications where aesthetics and precise dimensions are crucial. Jiuyang Steel Pipe Manufacturing Co., Ltd. offers square tubes in a vast range of sizes. The outer dimensions can vary from small, for light - weight applications like furniture frames, to large, which are commonly used in building structures and industrial machinery. The wall thicknesses of the square tubes can also be customized according to the specific requirements of customers. Whether it's a thin - walled square tube for decorative purposes or a thick - walled one for structural support, the company can meet the demand. Quality control is of utmost importance in the production of square tubes at this company. Each square tube is carefully inspected for dimensional accuracy, surface finish, and mechanical properties. Tensile strength, yield strength, and elongation tests are conducted to ensure that the products meet or exceed industry standards. In addition, non - destructive testing methods are used to detect any internal defects, guaranteeing the integrity of the square tubes. The company's square tubes are widely used in various industries. In the construction industry, they are used for building columns, beams, and scaffolding. In the automotive industry, square tubes are used in the manufacturing of vehicle chassis and frames. They are also used in the production of agricultural equipment, fencing, and furniture. With an annual sales revenue of 5 billion yuan and steel sales of several million tons, Shandong Liaocheng Jiuyang Steel Pipe Manufacturing Co., Ltd. has the resources and capabilities to handle large - scale orders. It also provides efficient logistics and delivery services to ensure that square tubes reach customers in a timely manner, both within China and overseas.
