1. Definition and Structural Composition‌ C-shaped steel, characterized by its longitudinal “C”-shaped cross-section, is a cold-formed or hot-rolled structural component widely used in construction and industrial engineering. Its geometry includes: Web‌: Central vertical plate (thickness: 1.5–6 mm) Flanges‌: Horizontal extensions (width: 30–100 mm) Lips‌: Reinforced edges (bend: 15–20 mm) for enhanced rigidity. 2. Manufacturing Processes‌ […]
