B：Germany - Automotive manufacturing industry
Heinz Muller - "We are a leading German automotive manufacturer that has long relied on high-quality precision steel pipes for the production of engine and chassis components. Before working with Sihua Precision Steel Pipe Company, we faced the problem of unstable dimensional accuracy of steel pipes, which led to the stagnation of the production line. However, since the use of your company's precision steel pipe, the precision and quality of the product are guaranteed. The surface treatment and corrosion
resistance of steel pipes allow our products to remain stable in high temperature and high load environments. We are very pleased to establish a long-term cooperative relationship with Sihua Precision Steel Pipe Company!"
