1. Gandheng kothak tabung punika kothak kothak kothak kothak baja tabung, uga dikenal minangka kothong kadhemen-kawangun baja. Iki kawangun dening mlengkung kadhemen lan welding frekuensi dhuwur sawise panas-mbalek utawa kadhemen-mbalek Strip utawa coil minangka kothong baja Shaped karo wangun salib-bagean kothak lan ukuran.
Saliyane ing thickening saka kekandelan tembok saka tabung kothak nglukis-walled, ukuran sudhut lan flatness pinggiran tekan utawa ngluwihi tingkat resistance gandheng tabung kothak kadhemen-kawangun. Ukuran amba R umume antarane 2 kaping lan 3 kaping kekandelan tembok. .Miturut kabutuhan pelanggan, kita uga bisa ngasilake tabung persegi sudut R kanthi ukuran sing dibutuhake pelanggan;
2. Tabung persegi Tabung persegi mulus yaiku jalur baja sing dawa kanthi bagean kothong lan ora ana sambungan ing pinggiran. Iki minangka tabung persegi sing dibentuk kanthi ngekstrusi tabung sing mulus liwat 4 sisi cetakan. Tabung kothak nduweni bagean kothong lan digunakake kanthi jumlah akeh. Iki digunakake ing transportasi Cairan, dhukungan hidraulik, struktur mekanik, tekanan medium lan kurang, tabung ketel tekanan dhuwur, tabung pertukaran panas, gas, petroleum lan industri liyane. Iku luwih kuwat tinimbang dilas lan ora bakal retak.
