Shandong Liaocheng Jiuyang Steel Pipe Manufacturing Co., Ltd., established in 2012 with a registered capital of 50 million yuan, is a leading manufacturer and supplier of high - strength square tube steel. As a professional enterprise integrating domestic and international trade and industry, it has extensive expertise in producing high - performance steel products to meet the demanding requirements of various industries. High - strength square tube steel is designed to withstand heavy loads and harsh environmental conditions. It is produced using advanced steel - making techniques and carefully selected high - grade raw materials. The chemical composition of the steel is precisely controlled to enhance its mechanical properties, such as tensile strength, yield strength, and impact resistance. The company's high - strength square tube steel production process involves a series of advanced manufacturing steps. It starts with the melting and refining of high - quality steel ingots in state - of - the - art furnaces. The refined steel is then hot - rolled or cold - formed into square tubes, depending on the specific requirements of the product. Hot - rolling is often used for larger - sized high - strength square tubes, as it can produce tubes with excellent mechanical properties and a relatively rough surface finish, which is suitable for applications where surface appearance is not the primary concern. Cold - forming, on the other hand, is preferred for smaller - sized or precision - required high - strength square tubes, as it offers better dimensional accuracy and a smoother surface. Jiuyang Steel Pipe Manufacturing Co., Ltd. offers high - strength square tube steel in a wide range of sizes and specifications. The outer dimensions can vary from small, for applications such as small - scale machinery frames, to large, which are commonly used in high - rise building structures and heavy - duty industrial equipment. The wall thicknesses of the high - strength square tubes are also customizable, allowing customers to choose the most suitable product for their load - bearing requirements. Quality control is a top priority in the production of high - strength square tube steel. The company has a sophisticated quality management system in place, which includes strict inspection at every stage of production. Mechanical property tests, such as tensile and impact tests, are conducted to ensure that the high - strength square tubes meet or exceed the required standards. Non - destructive testing methods, like ultrasonic and radiographic testing, are also used to detect any internal defects, ensuring the structural integrity of the products. The high - strength square tube steel products of this company are widely used in various industries. In the construction industry, they are used for building columns, beams, and braces in high - rise buildings, bridges, and large - scale industrial facilities. In the transportation industry, high - strength square tube steel is used in the manufacturing of truck frames, railway carriages, and ship structures. It is also used in the production of heavy - duty machinery, such as cranes and mining equipment. With an annual sales revenue of 5 billion yuan and steel sales of several million tons, the company has the production capacity and resources to meet large - scale orders for high - strength square tube steel. It also provides comprehensive after - sales services, including technical support and product maintenance advice.
