Ama-slab e-granite atholakala ezingqimbeni zemabula ezingaphansi komhlaba. Ngemva kwezigidi zeminyaka yokuguga, ukuma kwawo kuhlala kuzinzile ngokuphawulekayo, kususa ingozi yokuguquka ngenxa yokushintshashintsha kwezinga lokushisa okuvamile. Le nto ye-granite, ekhethwe ngokucophelela futhi yahlolwa ngokomzimba kanzima, inamakristalu amahle kanye nokuthungwa okuqinile, enamandla okucindezela angu-2290-3750 kg/cm² kanye nobunzima obungu-6-7 esikalini se-Mohs.
1. Ngokuyinhloko igxile ekuqondeni okuzinzile kanye nokulula kokugcinwa, ama-granite slabs anesakhiwo esincane esihle, indawo ebushelelezi, engagugi, kanye nobunzima obuphansi.
2. Ngemva kokuguga kwemvelo isikhathi eside, ama-granite slabs aqeda ukucindezeleka kwangaphakathi, okuholela ezintweni ezizinzile, ezingaguquki.
3. Amelana nama-acid, ama-alkali, ukugqwala, kanye ne-magnetism; amelana nomswakama nokugqwala, okwenza kube lula ukuwasebenzisa nokuyinakekela. Ane-coefficient yokukhulisa eqondile ephansi futhi awathinteki kakhulu yizinga lokushisa.
4. Imivimbo noma imihuzuko endaweni yokusebenza idala imigodi kuphela, engenazo izimbobo noma ama-burrs, angenawo umthelela ekunembeni kokulinganisa.
5. Ama-slab e-granite enziwe ngezingqimba zemabula ezingaphansi komhlaba. Ngemva kwezigidi zeminyaka yokuguga, ukuma kwawo kuhlala kuzinzile kakhulu, kususa ingozi yokuguquka ngenxa yokushintshashintsha kwezinga lokushisa. I-granite, ekhethwe ngokucophelela futhi yahlolwa ngokucophelela, inamakristalu amahle kanye nokuthungwa okuqinile. Amandla ayo okucindezela afinyelela ku-2290-3750 kg/cm², kanti ubulukhuni bayo bufinyelela ku-6-7 esikalini se-Mohs.
