GB angle steel is prevalent in:
China: Dominates domestic construction due to local production and standard compliance, with Q235/Q355 grades meeting GB 50017 design codes.
Southeast Asia: Countries like Vietnam, Indonesia, and Thailand adopt GB angle steel for infrastructure projects under the Belt and Road Initiative, leveraging China's manufacturing capacity and cost efficiency.
Africa: Used in public works (e.g., schools, hospitals) and energy projects, as Chinese contractors introduce GB standards to local markets.
Middle East: Adopted in oil & gas facilities and high-rise buildings, where GB angle steel's price-performance ratio outweighs European/American standards.
