Automotive Profile Roll-Forming Equipment Series—A specialized manufacturer offering comprehensive solutions covering the entire spectrum of vehicle body and structural components, with one-stop delivery from steel strip to finished product.
I.Series Overview
The Automotive Profile Roll Forming Equipment Series comprises complete production lines designed specifically for manufacturing various cold-formed profiles used in automotive bodies and structural components. Cold-formed steel refers to finished steel products with diverse cross-sectional shapes, created by bending steel plates or strips at ambient temperature; it is an economical, lightweight, thin-walled steel product. Cold-formed steel is widely utilized in the automotive industry, where it has replaced traditional stamped parts in many vehicle models.
The roll forming process employs a series of sequentially arranged forming rollers to continuously bend metal coils or strips transversely, enabling the rapid, continuous production of profiles with open, closed, or wide-section geometries. Compared to traditional stamping, roll forming offers significant advantages, including lower initial equipment investment, high production efficiency, superior material utilization, minimal springback, precise dimensional control, and consistent product quality.
This equipment series provides comprehensive roll forming solutions for a wide range of automotive profiles—including crash beams, fenders, chassis side rails, cargo body panels (box-type and fence-type), and window frames. It is compatible with various materials such as cold-rolled sheets, hot-rolled sheets, galvanized sheets, and high-strength steel, accommodating thicknesses from 0.8 mm to 6.0 mm and yield strengths up to 1180 MPa.
The products strictly comply with national standards such as GB/T 6726-2008 ("Dimensions, shape, weight and permissible deviations for cold-formed steel sections for automobiles") and YB/T 4623-2017 ("Cold-formed steel sections for automobile longitudinal beams").
