1. Welded square tube ke sekoti se sekoere karolo ea tšepe ea square tube, e tsejoang hape e le tšepe e sekoti e entsoeng ka serame.E entsoe ka ho kobeha ho batang le ho cheselletsa maqhubu a phahameng ka mor'a hore ho be le khoele e chesang kapa e batang e phuthoang e le tšepe e se nang letho e nang le sebopeho le boholo ba lisekoere.
Ho phaella ho thickening lerako botenya ba teteaneng-mabota lisekoere tube, boholo sekhutlo le bohale flatness fihla kapa feta boemo ba ho hanyetsa welded batang thehoa lisekoere tube.Boholo ba angle ea R hangata bo pakeng tsa makhetlo a 2 le makhetlo a 3 ho feta botenya ba lebota..Ho latela litlhoko tsa bareki, re ka boela ra hlahisa li-square tubes tsa R-angle tsa boholo bo hlokoang ke bareki;
2. Square tube seamless square tube ke lesela le lelelele la tšepe le nang le karolo e sekoti 'me ha le na manonyeletso periphery.Ke tube ea lisekoere e entsoeng ka ho ntša tube e se nang seam ka mahlakoreng a 4 a hlobo.Sekwere tube e na le karolo e sekoti 'me e sebelisoa ka bongata.E sebelisoa ho lipalangoang tsa metsi, ts'ehetso ea hydraulic, sebopeho sa mochini, khatello e mahareng le e tlase, tube ea boiler ea khatello e phahameng, tube ea phapanyetsano ea mocheso, khase, peterole le liindasteri tse ling.E matla ho feta welded mme e ke ke ea peperana.
