Shandong Liaocheng Jiuyang Steel Pipe Manufacturing Co., Ltd., a professional steel enterprise founded in 2012 with a registered capital of 50 million yuan, specializes in the production of square tube steel for the automotive industry. As a company that integrates domestic and international trade and industry, it has a deep understanding of the unique requirements and standards of the automotive sector. Square tube steel used in the automotive industry needs to meet strict quality and performance criteria. It must possess high strength, good formability, and excellent corrosion resistance. The company's square tube steel for automotive applications is designed and manufactured to meet these exacting requirements. The production process of automotive - grade square tube steel at Jiuyang Steel Pipe Manufacturing Co., Ltd. begins with the selection of premium - quality raw materials. Specialized steel alloys are chosen, taking into account factors such as strength - to - weight ratio, fatigue resistance, and weldability. These alloys are carefully processed to ensure consistent quality and performance. Advanced manufacturing techniques are employed to shape the steel into square tubes. Cold - forming is a commonly used method, as it allows for precise control of dimensions and can produce square tubes with a smooth surface finish, which is important for automotive components. The company also uses state - of - the - art rolling mills and forming equipment to ensure the accuracy and uniformity of the square tubes. The square tube steel for the automotive industry comes in various sizes and specifications. Smaller - sized square tubes are often used for interior components, such as seat frames and door reinforcements, where space constraints and weight reduction are important factors. Larger - sized square tubes are used for the vehicle chassis and frame, providing the necessary structural support and strength. Quality control in the production of automotive - grade square tube steel is extremely stringent. The company conducts a series of tests, including tensile strength tests, yield strength tests, and impact tests, to ensure that the square tubes can withstand the mechanical stresses encountered during vehicle operation. Corrosion resistance tests are also performed, as automotive components are exposed to various environmental conditions. Non - destructive testing methods are used to detect any internal flaws, ensuring the safety and reliability of the products. The company's square tube steel for the automotive industry is widely used by major automotive manufacturers. It plays a crucial role in enhancing the safety, durability, and performance of vehicles. Whether it's for passenger cars, commercial vehicles, or specialty vehicles, the company can provide suitable square tube steel solutions. With an annual sales revenue of 5 billion yuan and a large - scale production capacity, Shandong Liaocheng Jiuyang Steel Pipe Manufacturing Co., Ltd. can meet the large - volume demands of the automotive industry. It also offers technical support and customized solutions to automotive customers.
