China: Focuses on large-scale urbanization, using GB angle steel in high-rise apartments and industrial parks. Piv txwv li, L160 × 160 yog ib qho tshwm sim hauv Skyscraper cov qauv qauv.
Southeast Asia: Tus nqi ua ntej muaj txiaj ntsig rau kev daws teeb meem sai sai, nrog L63 × 6 dav hauv qhov chaw nyob thiab cov choj nyob deb nroog.
Africa: Ua Haujlwm GB lub kaum ntse ntse nyob rau hauv infrastructure tsis muaj cov txheej txheem nruj hauv zej zog, xws li L75 × 65 hauv cov tshuab hluav taws xob hauv nroog.
Middle East: Siv GB lub kaum ntse ntse nyob rau hauv iconic cov dej num zoo li chaw ua haujlwm (piv txwv li lub zog nrog kev ua kom zoo nkauj (piv txwv li galvanized L100 × 100 rau kev ua kom zoo nkauj sab nrauv).
Cov kev sib txawv no cuam tshuam sib txawv ua ntej, kev tsim kho cov cim, thiab cia siab rau Suav engineering kev txawj ntse hauv txhua cheeb tsam.
