Izinto zokwakha zeminyango yomlilo yeBanga B zihlanganisa ukhuni, insimbi, izinkuni zensimbi, njll. Umnyango ongashi wesigaba B udinga ukuthi ubuqotho bokumelana nomlilo bomzimba womnyango kumele budlule i-1h. Ipuleti le-electrolytic eliwugqinsi elingu-1.2mm noma ishidi elinothayela lizosetshenziselwa uhlaka lomnyango, futhi ipuleti le-electrolytic eliwugqinsi elingu-0.8mm noma ishidi elinothayela lizosetshenziswa eqabungeni lomnyango.

Iminyango yomlilo ye-ZHTdoors, iminyaka engu-31 yesipiliyoni sokukhiqiza eminyango yomlilo kanye neWindows. Iminyango yomlilo eyinhloko ye-UL, iminyango yomlilo ye-EN, iminyango yomlilo ye-BS EN, njll., Sine-certification.ZHTdoors isekela i-OEM kanye ne-design yamahhala.Izinzuzo zethu: ikhwalithi enhle, intengo yefekthri, isevisi enhle.Siyakwamukela ukuthi uxhumane nathi.
