Izipikili Zophahla Ezingagqwali Ezilwa Nokugqwala
Isicelo
Izipikili Zophahla Ezingagqwali Ezimelana Nokugqwala zifanelekela izinhlobo eziningi zokufakwa kophahla okuhlanganisa ama-shingle e-asphalt, ama-shingle e-cedar, ama-shingle obumba nokhonkolo, kanye nezinto zokuphahla zensimbi. Zifaneleka futhi ukusetshenziswa emimoyeni enamandla nasezindaweni ezisogwini lapho amanzi olwandle nomswakama kungadala ukugqwala.
Lezi zipikili zingasetshenziswa ukufaka uphahla olusha, kanye nokulungisa nokufaka esikhundleni sezinto zophahla ezonakele. Zifaneleka nakwezinye izinhlelo zokwakha lapho ukumelana nokugqwala kubalulekile khona, njengokubiyela, ukuhlobisa amafasitela kanye nokuhlobisa ngamapulangwe.
Isici
Ngaphezu kokuba nezipikili zophahla ezimelana nokugqwala nokugqwala, insimbi engagqwali evikela ukugqwala inezinye izici eziningi ezenza zifaneleke kakhulu ekufakweni kophahla. Lokhu kufaka phakathi:
1. Amandla aphezulu okubambelela: Izipikili zensimbi engagqwali ziqinile kakhulu futhi zingamelana nesisindo kanye nengcindezi yezinto ezisindayo zokufulela.
2. Ukuhambisana nezinto ezahlukene zokufulela: Lezi zipikili zingasetshenziswa nezinto ezahlukahlukene zokufulela, okwenza zibe nezimo eziningi futhi zibe wusizo.
3. Ukufakwa okulula: Amaphuzu abukhali kanye nezinsika zezinzipho kwenza kube lula ukuzibethela ezintweni zokuphahla ngaphandle kokulimaza indawo.
4. Ihlala isikhathi eside: Izipikili zensimbi engagqwali zenzelwe ukuhlala iminyaka eminingi ngaphandle kokugqwala, ukugqwala noma ukonakala, okwenza zibe ukukhetha okungabizi kakhulu kokusetshenziswa kophahla

Izipikili Zokuklama Ngokwezifiso

I-Yihe Enterprise yinkampani egxile ekuklameni nasekukhiqizweni kwezipikili, izinzipho eziyisikwele, ukugoqa kwezipikili, zonke izinhlobo zezipikili nezikulufo ezibunjwe ngendlela ekhethekile. Ukukhetha izinto zezipikili zensimbi yekhabhoni esezingeni eliphezulu, ithusi, i-aluminium kanye nensimbi engagqwali, futhi ingenza ukwelashwa okushisayo, okushisayo, okumnyama, ithusi nokunye okungaphezulu kuye ngesidingo samakhasimende. Isikulufo esiyinhloko ukukhiqiza izikulufo zomshini ezenziwe e-US ze-ANSI, isikulufo somshini we-BS, i-bolt corrugated, kufaka phakathi i-2BA, i-3BA, i-4BA; izikulufo zomshini ezenziwe eJalimane i-DIN (DIN84/ DIN963/ DIN7985/ DIN966/ DIN964/ DIN967); Uchungechunge lwe-GB kanye nezinye izinhlobo zemikhiqizo ejwayelekile nengeyona ejwayelekile njengezikulufo zomshini nazo zonke izinhlobo zezikulufo zomshini wethusi.
Umkhiqizo wethu ungasetshenziswa efenisha yehhovisi, embonini yemikhumbi, yesitimela, yokwakha, embonini yezimoto. Ngezinhlelo zokusebenza eziningi ezifanele imikhakha eyahlukene, umkhiqizo wethu uvelele ngekhwalithi yawo eyingqayizivele—wenziwe ngezinto zekhwalithi ephezulu namasu okukhiqiza athuthukile ukuqinisekisa ukuqina nokusebenza kahle. Ngaphezu kwalokho, sigcina isitokwe esanele ngaso sonke isikhathi, ukuze ukwazi ukujabulela ukulethwa okusheshayo futhi ugweme ukubambezeleka kumaphrojekthi akho noma ekusebenzeni kwebhizinisi, kungakhathaliseki ukuthi ungakanani u-oda.
Inqubo yethu yokukhiqiza ichazwa ubuciko obuhle kakhulu—isekelwa ubuchwepheshe obuthuthukisiwe kanye nabadwebi abanekhono, sithuthukisa zonke izinyathelo zokukhiqiza ukuqinisekisa ukunemba kanye nobuhle kuwo wonke umkhiqizo. Sisebenzisa izinqubo zokulawula ikhwalithi eziqinile ezingashiyi ndawo yokuyekethisa: izinto zokusetshenziswa zihlolwa ngokucophelela, imingcele yokukhiqiza iqashelwa eduze, futhi imikhiqizo yokugcina ihlolwa ngekhwalithi ephelele. Siqhutshwa ukuzinikela ekwenzeni kahle, silwela ukwakha imikhiqizo yekhwalithi ephezulu evelele emakethe ngekhwalithi yayo ephezulu kanye nenani elihlala isikhathi eside.
