1. Simple section square tube: square chubhu, rectangular square chubhu.
2. Square chubhu ine chikamu chakaoma: ruva rakaita square chubhu, yakavhurika square chubhu, corrugated square chubhu uye yakakosha-yakaumbwa square chubhu.
Surface treatment classification
Mapaipi epamativi akakamurwa kuita hot-dip galvanized square pombi, electro galvanized square pombi, oiled square pombi uye pickled square pombi zvinoenderana nepamusoro kurapwa.
Shandisa classification
Square machubhu anoiswa maererano nechinangwa: masikweya machubhu ekushongedza, sikweya machubhu echishandiso chemuchina, masikweya machubhu eindasitiri yemakemikari, sikweya machubhu eindasitiri yemakemikari, masikweya machubhu echimiro chesimbi, sikweya machubhu ekuvaka ngarava, sikweya machubhu emotokari, masikweya machubhu e. matanda esimbi nemakoramu, nemachubhu masikweya ezvinangwa zvakakosha.
Wall ukobvu classification
Rectangular machubhu akaiswa maererano nehukobvu hwemadziro: akawedzera gobvu akakomberedzwa rectangular chubhu, gobvu madziro ane rectangular machubhu uye matete-akavakirwa rectangular chubhu.
