1. Welded square chubhu ihollow square section steel square chubhu, inozivikanwawo sehollow cold-formed steel.Iyo inogadzirwa neinotonhora kukotama uye yakakwirira-frequency welding mushure mekupisa-yakakungurutswa kana kutonhora-yakakungurutswa tambo kana coil seyakashama Yakaumbwa simbi ine sikweya-chikamu chechikamu chimiro uye saizi.
Pamusoro pekukora kwemadziro ehukobvu-walled square chubhu, ukuru hwekona uye kumucheto flatness inosvika kana kudarika mwero wekupikisa welded cold-formed square chubhu.Saizi yeR angle inowanzova pakati pe2 nguva uye 3 nguva ukobvu hwemadziro..Maererano nezvinodiwa nevatengi, tinogonawo kugadzira R-angle square tubes yehukuru hunodiwa nevatengi;
2. Square chubhu Seamless square chubhu isimbi yakareba tambo ine mhango chikamu uye isina majoini painotenderera.Ichubhu yeskweya inogadzirwa nekuburitsa chubhu isina musono kuburikidza nemativi mana eforoma.Iyo square chubhu ine mhango chikamu uye inoshandiswa muhuwandu hukuru.Inoshandiswa mukufambisa kwemvura, hydraulic tsigiro, dhizaini chimiro, yepakati uye yakaderera kudzvanywa, yakanyanya kumanikidza boiler chubhu, kupisa kupisa chubhu, gasi, peturu uye mamwe maindasitiri.Iyo yakasimba kudarika welded uye haizotsemuka.
