Automotive Precision
Precision steel pipes are widely used in automotive parts. The materials are mostly 20#, 45#, 16Mn, etc. They are suitable for manufacturing drive shafts, shock absorbers, steering systems and other parts. The common specifications of steel pipes are outer diameter φ10-φ200mm with the thickness 1-20mm.
Great Wall provides advanced tube mill solutions for automotive precision applications, designed for manufacturing high-accuracy steel tubes used in automotive chassis, exhaust systems, seat frames, shock absorbers, steering systems, and structural components.
Our tube production line can produce precision automotive steel pipes. The precision steel pipes produced have the characteristics of high dimensional accuracy and smooth and flawless surface, which can not only improve the appearance of the product, but also ensure the performance and life of the product.
Automotive steel tubes require:
Tight dimensional tolerances
Consistent wall thickness
Smooth weld seams
High structural strength
Stable mechanical performance
Even small deviations may affect vehicle safety, assembly precision, and product durability. Great Wall’s automotive metal pipe making machines ensure stable forming and welding for demanding automotive applications.
