St52-3G carbon structural steel plates and strips are featured with good comprehensive mechanical performance (strength and percent elongation, etc.) and process performance (bending ), high dimensional accuracy and excellent welding performance. They are suitable to manufacturing structural members with simple processing and may be used as some structural parts for automobiles, such as car body frames, middle base plates and various reinforcement plates.

St52-3G carbon structural steel surface quality:
Relatively high-grade finishing surface FB(03)-It is allowed for the existence of a few surface defects which will not affect forming and coating & plating adhesiveness such as minor scratch, impression, pit, roll mark and oxidation tint.
High-grade finishing surface FC(04)-One side of relatively good quality is free from any remarkable defect visible and the other side must reach FB requirements at least.
