Automotive Interior Steel Tube Solutions

Steel pipes have always played a vital role in automotive interior structures, from vehicle frames to instrument panels. While not particularly noticeable, they quietly contribute to a comfortable and safe driving experience for drivers and passengers worldwide. Today, we'll briefly introduce a few areas where steel pipes are used in automotive interiors.

Automotive Seat Tubes

Automotive seat tubes are typically manufactured from CDW cold-drawn welded tubes. They are key load-bearing components of the seat frame. Common grades include STKM 11A 12A, E235 E355, and SAE 1010 1020 1026. They are widely used in front and rear seat frames, backrest supports, slide rail connectors, and adjustment mechanisms, providing reliable support and safety for the vehicle.

Steering Column and Pedal Brackets

The steel pipes used in steering columns and pedal brackets are typically DOM and seamless steel pipes. High-strength, impact-resistant steel is typically used for these steel pipes to ensure safety under harsh operating conditions. Common materials include high-strength low-alloy steel (STKM11A, 12A, and 13A), a type of precision steel tube. Precision-manufactured steel tubes not only ensure the stability and durability of these two systems but also protect the driver's life in a collision.

Dashboard crossbeams

Steel tubes are also common in automotive dashboards. These tubes are typically made from high-strength welded and hydroformed tubes. STKM14A, E355, and HSLA grades are common grades. They not only provide support for the dashboard but also protect the vehicle in a collision.

Although invisible, automotive interior steel tubes serve as the invisible framework of modern vehicles, playing a vital role in safety, comfort, and lightweight design. With the development of the automotive industry, demand for precision electric resistance welded, longitudinally welded, seamless, and hydroformed tubes in grades such as STKM, E235/E355, SAE 1010–1026, and 22MnB5 will continue to grow.
