Iliphi Ishidi Lophahla Elingcono Kakhulu?

Ukukhetha impahla yokufulela efaneleke kakhulu kuyisinqumo esibucayi esithinta kakhulu ukuphila isikhathi eside, ukonga kwamandla, kanye nokukhanga kobuhle besakhiwo. Imakethe inikezela ngezinhlobo ezahlukahlukene izinketho zeshidi lokufulela , ngalinye linezakhiwo ezihlukile eziklanyelwe izimo ezithile zemvelo kanye nezidingo zezakhiwo. Lokhu kuhlaziya okuphelele kuhlola amashidi okufulela ahlukahlukene, ukuhlola izinto zawo, izinzuzo, izithiyo, kanye nezinhlelo zokusebenza ezikahle zokuqondisa ababambiqhaza ekwenzeni izinqumo ezinolwazi.

Metal Roofing Sheets

I-Aluminium Roofing Sheets

Amashidi okufulela e-aluminium adume ngobulula bawo kanye nokumelana nokugqwala okukhethekile. Isisindo esingaba amakhilogremu angu-5 ngonyawo lwesikwele ngasinye, zenza umthwalo omncane wesakhiwo uma uqhathaniswa nezinto ezivamile. I-Aluminium ngokwemvelo yakha ungqimba lwe-oxide oluvikelayo, oluthuthukisa ukuqina kwayo, ikakhulukazi ezindaweni ezisogwini lapho ukugqwala kwamanzi anosawoti kwande. Ngokusho kwe-Aluminium Association, uphahla lwe-aluminium lungahlala iminyaka engu-50 ngokulungiswa okuncane. Ukwengeza, ukubonakala kwabo okuphezulu-okufika ku-90% wemisebe yelanga-kunikela ekusebenzeni kahle kwamandla ngokunciphisa izindleko zokupholisa ezindaweni ezishisayo.

Amashidi Okufulela Ensimbi Avunyiwe

Amashidi okufulela ngothayela angamashidi ensimbi ambozwe ngongqimba lwezinki ngenqubo yokudipha okushisayo, ahlinzeke umgoqo oqinile wokungagqwala. I-zinc isebenza njenge-anode yomhlatshelo, ivikela insimbi engaphansi ngisho noma ingaphezulu liklwetshiwe. Lolu hlobo lokufulela alubizi futhi lunikeza isikhathi sokuphila seminyaka engama-25 kuya kwengama-60, kuye ngezici zemvelo. Ucwaningo oluvela ku-National Association of Corrosion Engineers lubonisa ukuthi ukumbozwa kukathayela ezindaweni zasemakhaya kungavikela insimbi iminyaka engaphezu kwamashumi amahlanu. Ukutholakala kwazo kanye nokuthengeka kwazo kuzenza zibe ukukhetha okudumile ekwakhiweni kwezindawo zokuhlala nezokuhweba.

Steel Roofing Sheets

Amashidi okufulela ensimbi ayaziwa ngamandla awo nokuguquguquka. Bangakwazi ukumelana nezimo zezulu ezimbi kakhulu, okuhlanganisa imithwalo yeqhwa esindayo kanye nemimoya ephezulu efinyelela ku-140 mph. Izinto ezintsha ezifana ne-Galvalume—i-zinc ne-aluminium—ithuthukisa ukumelana nokugqwala kwensimbi. Ucwaningo olwenziwe yiMetal Construction Association luveza ukuthi ukufulela insimbi yeGalvalume kungahlala iminyaka efinyelela kwengama-60. Uphahla lwensimbi luphinde luwonge ugesi uma lumbozwe ngemibala ekhanyayo, olunganciphisa izindleko zokupholisa kuze kufike ku-25%. Ziyakwazi ukuphinda zisetshenziswe, zihambisana nezinqubo zokwakha ezisimeme.

Amashidi ophahla e-Aluzinc

Amashidi okufulela e-Aluzinc ahlanganisa insimbi ehlanganiswe ne-alloy engu-55% aluminium, 43.4% zinc, kanye ne-silicon engu-1.6%. Lokhu kwakheka kuhlanganisa ukumelana nokugqwala kwe-aluminium nokuvikelwa kwe-galvanic ye-zinc. Uphahla lwe-Aluzinc lubonisa ukusebenza okuphezulu ezindaweni ezinokhahlo, kuhlanganise nezimboni nezasolwandle. Ucwaningo lubonisa ukuthi izimbobo ze-Aluzinc zingahlala isikhathi esiphindwe kane kune-galvanization yendabuko. Ukubukeka kwabo okushisayo kunciphisa ukudluliswa kokushisa, kuthuthukisa ukunethezeka kwangaphakathi. Inhlanganisela yokuqina nokusebenza kahle kwamandla kwenza i-Aluzinc ibe yisinqumo esihle kakhulu sezinhlelo zokusebenza zesikhathi eside.

Plastic Roofing Sheets

Amashidi ophahla e-PVC

Amashidi ophahla e-PVC (i-Polyvinyl Chloride) ayisixazululo esingasindi futhi esingabizi kakhulu esivame ukusetshenziswa ezakhiweni zezolimo, zezimboni, nezindawo zokuhlala. Zinikeza ukumelana okuhle kwamakhemikhali futhi azikwazi ukugqwala nokubola. Uphahla lwe-PVC kulula ukulufaka futhi ludinga ukulungiswa okuncane. Kodwa-ke, angeke anikeze izinga elifanayo lokuqina njengophahla lwensimbi ngaphansi kwezimo zezulu ezimbi kakhulu. Intuthuko ekukhiqizeni iholele ekuqinisweni kwemikhiqizo yokufulela ye-PVC ethuthukisa amandla nempilo yokuphila, iyenze ifanelekele uhla olubanzi lwezinhlelo zokusebenza.

I-Polycarbonate Roofing Sheets

Amashidi okufulela e-Polycarbonate aziwa ngokumelana kwawo okukhethekile nokungafihli lutho, okuvumela ukudluliswa kokukhanya okungafika ku-90%. Zilungele izakhiwo ezidinga ukukhanya kwemvelo, njengezindlu zokugcina izithombo, ama-skylights, nama-carports. I-Polycarbonate inamandla izikhathi ezingu-200 kunengilazi futhi ingamelana nezinga lokushisa elidlulele ukusuka ku -40°F ukuya ku-240°F. Izembatho ezimelana ne-UV zithuthukisa ukuqina kwazo ngokuvimbela ukonakala okuvela ekuchayekeni elangeni. Naphezu kwezinzuzo zabo, uphahla lwe-polycarbonate lungabiza kakhulu kunezinye izinketho zepulasitiki futhi lunganweba noma lube nenkontileka ngokushintshashintsha kwezinga lokushisa, okudinga ukufakwa ngokucophelela.

Ukuhlaziya Ngokuqhathanisa

Lapho uqhathanisa izinto zokuphahla, izici eziningana kufanele zibhekwe:

• Ukuqina: Uphahla lwensimbi, ikakhulukazi lelo elenziwe ngensimbi, i-aluminium, noma i-Aluzinc, linikeza impilo ende ephakeme, evamise ukudlula iminyaka engu-50.

• Izindleko: Amashidi othayela othayela kanye namashidi okufulela e-PVC ngokuvamile athengeka kakhulu ngaphambili kodwa angase abe nezindleko zokunakekela eziphakeme zesikhathi eside.

• Umthelela Wendawo Ezungezile: Amashidi okufulela ensimbi ayasebenziseka kabusha futhi angaba nomthelela ekusebenzeni kahle kwamandla, kuyilapho izinketho zepulasitiki zingase zingabi nobungane njengemvelo.

• I-Aesthetics: Uphahla lwensimbi lunikeza izinhlobonhlobo zokuqeda kanye namaphrofayili, okuthuthukisa ukukhanga kwezakhiwo, kuyilapho amashidi e-polycarbonate enikeza izinketho eziyingqayizivele ezisobala noma eziguquguqukayo.

• Ukufaka Nokunakekela: Izinto ezingasindi njenge-aluminium ne-PVC kulula ukuzifaka, kunciphisa izindleko zabasebenzi.

I-Case Studies

Ucwaningo olwenziwa yi-Cool Roof Rating Council lubonise ukuthi uphahla lwe-aluminium nolwensimbi olunamatshe akhanyayo anciphisa kakhulu iziqhingi zokushisa zasemadolobheni. Ezicelweni zokuhlala, abanikazi bezindlu babike ukonga amandla okungafika ku-20% ngemva kokufaka uphahla lwensimbi olukhanyayo. Izakhiwo zezimboni ezisebenzisa amashidi okufulela e-Aluzinc ziye zaphawula ubude besikhathi eside sophahla kanye nokunciphisa izindleko zokulungisa. Ezilungiselelweni zezolimo, ukufulela kwe-polycarbonate kuthuthukise ukukhula kwezitshalo ngokukhulisa ukukhanya kwemvelo ngenkathi kunikeza indawo yokukhosela.

Imibono yongoti

Ochwepheshe bezokwakha bagcizelela ukubaluleka kokukhetha izinto zokuphahla ngokusekelwe ezidingweni ezithile zephrojekthi. UDkt. Emily Sanders, uchwepheshe wezokwakha okusimeme, uthi, 'Ukukhetha impahla yokufulela efanele kuhilela ukulinganisa izindleko zokuqala nezinzuzo zesikhathi eside. Uphahla lwensimbi, nakuba lubiza kakhulu ngaphambili, lunikeza ukuqina okungenakuqhathaniswa namandla okusebenza kahle.' Ngokufanayo, unjiniyela wezokwakha u-John Mitchell ugqamisa, 'Ngezakhiwo ezisezindaweni ezibolayo,' uphahla luhlinzeka ngezinto zokwakha ezingcono kakhulu ezifana ne-Aluzinc.

Isiphetho

Ukunquma ishidi lokufulela elingcono kakhulu kuncike ezintweni ezihlukahlukene ezihlanganisa izimo zemvelo, imingcele yesabelomali, izidingo zesakhiwo, kanye nezintandokazi zobuhle. Amashidi okufulela ensimbi afana ne-aluminium, i-galvanized iron, steel, ne-Aluzinc anikeza ukuqina nokusebenza kahle kwamandla, okuwenza afanelekele uhla olubanzi lwezinhlelo zokusebenza. Izinketho zepulasitiki ezifana ne-PVC kanye namashidi okufulela e-polycarbonate ahlinzeka ngezixazululo ezingabizi futhi ezingasindi zezidingo ezithile, ikakhulukazi lapho kufunwa ukukhanya kwemvelo. Ukubonisana nezingcweti zemboni nokucabangela izici ezihlukile zesakhiwo kubalulekile ekwenzeni ukukhetha okufanele. Kulabo abafuna izinketho zamandla aphezulu, ukumelana nokugqwala, ukuhlola imikhiqizo yeshidi lokufulela ngensimbi ingase inikeze inani elingcono kakhulu lesikhathi eside.
