1. Imisebenzi eyahlukeneyo: Iintambo zombane zisetyenziswa kumqolo weenkqubo zamandla ukuhambisa nokusasaza amandla amakhulu ombane asebenzayo; Iintambo zokulawula zisetyenziselwa ukulawula iintambo zombane kunye nezixhobo zombane.
2. Iindidi ezahlukeneyo: Iintambo zombane zodidi lwesibini kwiindidi ezintlanu eziphambili zeentambo; Iintambo zokulawula zikodidi lwesithathu kwiindidi ezintlanu eziphambili zeentambo (iintambo zezixhobo zombane).
3. Imigangatho eyahlukeneyo: Umgangatho weentambo zombane yi-GB12706; Umgangatho weentambo zokulawula yi-9330.
4. Ukuchongwa kweengcingo ze-insulated core kwahlukile: ukugquma kweentambo zamandla ngokuqhelekileyo kuthatha ukuhlukana kwesigaba sombala; Umbala we-insulation core yekhebula lokulawula ngokuqhelekileyo umbala owodwa oshicilelwe ngamanani amanani.
5. Iingcombolo zekhebhile: Iintambo zombane zisetyenziselwa ukuhambisa umbane, kwaye iinkcukacha ezisetyenziswayo zidla ngokuba zikhulu, ezinokuthi zilungelelaniswe ukuya kuthi ga kwi-500 square metres; Indawo enqamlezileyo yekhebula yokulawula incinci, ngokuqhelekileyo ayidluli kwiimitha ezili-square ezili-10
