China: Focuses on large-scale urbanization, using GB angle steel in high-rise apartments and industrial parks. For example, L160×160×14 is common in skyscraper core structures.
Southeast Asia: Prioritizes cost-effective solutions for rapid urban growth, with L63×63×6 widely used in low-rise housing and rural bridges.
Africa: Employs GB angle steel in infrastructure lacking strict local standards, such as L75×75×8 in rural water supply systems.
Middle East: Uses GB angle steel in iconic projects like stadiums and malls, combining its strength with decorative finishes (e.g., galvanized L100×100×8 for aesthetic bracings).
These differences reflect varying economic priorities, construction codes, and reliance on Chinese engineering expertise in each region.
