Success Cases

● Customer background: A well-known automobile manufacturer, focusing on the production of mid-to-high-end passenger cars, has extremely high requirements for vehicle body strength and safety.

● Challenges: During the development of new models, it is necessary to find body structure materials that can meet high strength requirements while achieving lightweight design within a reasonable cost range.

● Gangtuo Solution: Gangtuo recommended its own high-quality seamless steel pipes for key supporting structures, such as frame longitudinal beams. Their good compressive strength and toughness ensured the safety of the vehicle body in collisions. At the same time, H-shaped steel was used in some reinforced areas of the body frame. The reasonable cross-sectional shape and mechanical properties of the H-shaped steel were used to improve the rigidity of the entire body without adding too much weight.

● Results: The new model passed the strict collision test, and the body structure integrity was excellent. At the same time, due to the reasonable selection of materials, it achieved a certain degree of lightness and improved fuel economy. After the model was launched, it was widely praised by consumers for its excellent safety performance and good handling. The market sales far exceeded expectations. As a result, Santuo's metal materials were highly recognized by automobile manufacturers and a long-term cooperative relationship was established.

● Customer background: A supplier specializing in the production of automotive chassis parts, supplying products to many mainstream automobile brands.

● Challenges: Chassis components need to have good corrosion resistance to cope with complex road conditions and different climatic conditions, while also ensuring the processing performance of the material to facilitate stamping, cutting and other processes.

● Gangtuo Solution: Gangtuo provides galvanized steel coils and sheets that have undergone rigorous quality testing. The galvanized layer effectively protects the steel surface from corrosion and extends the service life of the parts; and these materials have good processing performance and can be smoothly passed through the supplier's stamping line to accurately form the required chassis parts, such as brake disc guards, chassis reinforcement plates, etc.

● Results: Chassis parts produced using Santo's galvanized steel coils and sheets have shown excellent corrosion resistance in actual use, greatly reducing the frequency of parts replacement due to corrosion. This not only improves the overall reliability of the car, but also wins a better reputation for the car brand. Santo has also further expanded its market share in the field of automotive parts supply with its stable product quality.

● Client Background: An emerging electric vehicle manufacturer that focuses on the quality and aesthetics of vehicle interiors and is committed to creating a high-end and comfortable driving environment.

● Challenges: We need to find materials suitable for interior decoration parts, which must have good surface gloss, wear resistance, and meet environmental protection requirements.

● Gangtuo Solution: Gangtuo recommended stainless steel plates with fine surface treatment for center console decorative strips, door interior handles and other parts. Their bright surface can enhance the overall texture of the interior. At the same time, aluminum coils are used to process and make some lightweight decorative panels for the interior. The lightweight characteristics of aluminum coils help reduce the weight of the car body, and their strong machinability can produce a variety of unique shapes.

● Results: As soon as the interior of the electric car was unveiled, it was highly praised by consumers for its exquisite decorative effects and comfortable driving experience. The interior parts made of stainless steel plates and aluminum coils are not only beautiful and durable, but also meet environmental standards, helping automakers stand out in the high-end electric vehicle market. Gangtuo has also successfully entered the electric vehicle interior material supply market and has launched cooperation negotiations with more auto brands.
