Izikhonkwane zokufulela nge-Electro-Galvanized

Inkcazelo emfutshane:

Izikhonkwane zophahla lwegalvanized yenye yezona zinto zixhaphakileyo zisetyenziswa kwishishini lokuphahla.Ukwakhiwa kwabo okuhlala ixesha elide kunye nokuthembekileyo kubenza balungele ukukhusela zonke iintlobo zezinto zokuphahla, ukusuka kwii-shingles ukuya kwii-tile, iipaneli zetsimbi kunye nokunye.Ezi zikhonkwane ziza ngobukhulu obuhlukeneyo kunye nezitayela, nganye yenzelwe ukuhlangabezana neemfuno ezithile zokuphahla.Kule nqaku, siza kuhlolisisa inkcazo, ukusetyenziswa kunye neempawu zezikhonkwane zokuphahla.

Isicelo

Izikhonkwane zophahla ziyi-fasteners ezilungiselelwe ngokukodwa ezisetyenziselwa ukukhusela izinto zokuphahla kwindawo engaphantsi.Ziza ngobude obuhlukeneyo, ukusuka kwi-1 ukuya kwi-6 intshi, kuxhomekeke kwiimfuno zephahla.Ngokukodwa, izikhonkwane zokuphahla zifakwe kwi-zinc ukukhusela i-rust kunye ne-corrosion.Oku kuthetha ukuba zifanelekile kwizicelo zophahla lwangaphandle apho ziyakwazi ukumelana neemeko zemozulu ezinzima ngaphandle kokuwohloka.

Izicelo zezikhonkwane zokuphahla ziyahlukahlukana.Zingasetyenziselwa ukukhusela iintlobo ezahlukeneyo zezinto zokuphahla, kuquka i-asphalt shingles, i-shingles, i-sheet metal, kunye ne-ceramic tile.Ukongezelela, zingasetyenziselwa ukujoyina iinkqubo ze-gutter, i-fascias kunye nokukhanya.Ukuguquguquka kwezikhonkwane zophahla lwezikhonkwane kuzenza zibe lukhetho oludumileyo phakathi kweekontraka zokuphahla kunye ne-DIYers ngokufanayo.

Uphawu

Ngokusebenzayo, izikhonkwane zophahla eziphekiweyo ziyaziwa ngamandla azo aphezulu, ezivumela ukuba zimelane noxinzelelo olugqithisileyo kunye noxinzelelo.Banentloko ethe tyaba eyenza kube lula ukuqhuba kwizinto ezifulelweyo ngaphandle kokuwonakalisa.Ngaphezu koko, iingcebiso zabo ezibukhali zivumela ukuba bangene kwizinto ezinqabileyo zokuphahla ngokulula, ukwenza ukufakela ngokukhawuleza kwaye kulula.Ngokubanzi, izikhonkwane zokuphahla zinamandla kakhulu, zithembekile kwaye zineendleko.
