A: Ndife opanga mwachindunjiChitoliro chachitsulo cha API 5L,yopanda msoko,ERW, LSAW, DSAW, SSAW, HSAW chitoliro chokhala ndi satifiketi yonse.

Q2: Kodi mungapereke mitengo yolunjika ku fakitale?

A: Inde, monga wopanga, titha kukupatsani mtengo wopikisana wa fakitale popanda anthu apakati, ndipo zidzakhala zotsika mtengo kwambiri pamapulojekiti anu.

Q3: Kodi mungandidziwitse ngati muli ndi katundu woti mugule mwachangu?

A: Inde, tili ndi katundu wambiri wa magiredi ndi makulidwe wamba omwe akugwirizana ndi zosowa zanu.

Q4: Kodi mungapereke zikalata ndi satifiketi zotumizira kunja?

A: Ndithudi. Timapereka zikalata zonse zofunika zotumizira kunja ndi mayeso (masatifiketi oyesera a API 5L, satifiketi ya mphero, malipoti a mankhwala ndi makina ndi zikalata zina zilizonse monga momwe malamulo otumizira kunja amafunira).
