Uma kudingekile ukudlula phakathi kwezingxenye zomlilo zesakhiwo, iminyango yomlilo ye-Class A (ukumelana nomlilo 1.2h) izomiswa. Uma kwenzeka umlilo esakhiweni, ungavimbela noma ubambezele ukubhebhetheka komlilo ngezinga elithile. Iminyango yomlilo kufanele ibe nokukhethwa kwezinto ezibonakalayo, isakhiwo esihle nokumelana nomlilo okuthembekile. Khumbula ukuthi ungawugcini umnyango womlilo isikhathi eside, ungavimbi noma ukhiye umnyango womlilo.

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.
