Emnyango womlilo wensimbi, umsebenzi we-A-class steel fire door unamandla kakhulu. Ukumelana nomlilo kwayo kungamahora angu-1.5, okungenakwenzeka eminyango yomlilo yekilasi B kanye neklasi C. Ngokuvamile, iminyango yomlilo yensimbi iyisigaba esiwusizo kakhulu.

umnyango nohlaka lwensimbi yokuphepha yangaphandle,umnyango womlilo vs umnyango ojwayelekile, ipuleti lokukhahlela lomnyango elilinganiselwe umlilo,izibambo zomnyango wokuphepha wensimbi nezingidi, umnyango wezokuphepha wensimbi vs aluminium,

umenzi wezicabha ezikwazi ukumelana nomlilo,insimbi yangaphandle umnyango wokuphepha kanye nohlaka,umnyango omkhulu ongashi, impahla yomnyango wokufaka umlilo,izibambo zezicabha zensimbi zokuphepha nezingidi,Ubukhulu bomnyango obukalwe ngomlilo, umnyango wensimbi x, ukusetshenziswa komnyango wokuphuma ezimeni eziphuthumayo, umnyango olinganiselwe umlilo iminithi engama-90,insimbi vs umnyango wezokuphepha we-aluminium,

iminyango yamapulangwe engashi,insimbi yangaphandle umnyango wokuphepha kanye nohlaka,ukusetshenziswa komnyango wokuphuma ezimeni eziphuthumayo, umnyango olinganiselwe umlilo, indawo yokuhlala elinganiselwe umlilo
