Malinga ndi kupanga ndi kukonza njira, zitha kugawidwa m'magulu otsatirawa:

①Pepala la PPGI. Phungu loonda lokhala ndi zinc yosenda limabisidwa pansi pomiza mu kusamba kosungunuka. Pakadali pano, zimatengera nthawi yopitilira, kuti, mbale yachitsulo yopezeka mosalekeza imamizidwa mosalekeza mu thanki yotchuka ndikuphatikizidwa ndi zosungunuka ndikupanga mbale yachitsulo.

②aLolor Garvanized Board. Nsanja yamtunduwu imapangidwanso ndi njira yotentha yotentha, koma itachotsedwa ku thankiyo, imathamangira pafupifupi 500 ° C kuti apange filimu ya Aloy ndi chitsulo. Mapepala ankhondo amakhala ndi utoto wabwino komanso utope;

③ectro-Pepala la PPGI. Ma sheese achitsulo omwe amapangidwa ndi njira zamagetsi amagwirira ntchito bwino. Komabe, zokutira ndi zocheperako ndipo kukana kwake kuvunda sikuli bwino ngati pepala lotentha.

④ Mabodi onyamula mbali imodzi ndi mbali ziwiri. Padels a Getvanized Shalvased zitsulo ndi zinthu zomwe zimapangidwa mbali imodzi yokha. Pankhani yotchetcha, penti, dzimbiri, chithandizo cha dzimbiri, kukonza, ndi zina zambiri, kumakhala bwino kuposa ma sheet awiri ozungulira. Pofuna kuthana ndi zolakwa za kusagawidwa mbali imodzi, mtundu wina wa pepala la galvanated ndi wowonda kwambiri wokhala ndi zitsulo mbali inayo, ndiye kuti, pepala lolumikizana kawiri.

⑤arloy ndi mtundu wa gulu lankhondo lankhondo. Ndi mbale yachitsulo yopangidwa ndi zitsulo ndi zitsulo zina (monga kutsogolera ndi zinc Hamoys) kapenanso kuphatikizika. Mtundu wamtunduwu suli wokhalitsa wa dzimbiri, komanso ali ndi zokutira bwino.
