Takulandirani ku dziko lodabwitsa la mapepala okhala ndi utoto! Ngati mukuvutikabe kusankha pakati pa mapepala okhala ndi utoto wotentha (PPGI), aluminized zinc (PPGL), kapena mapepala okhala ndi utoto wopangidwa ndi utoto wa premium zinc-aluminium-magnesium alloy, simuli nokha. Tiyeni tifufuze tsatanetsatane wa zipangizozi kuti zikuthandizeni kusankha bwino zomwe mukufuna padenga lanu, koma zinthu zonse zizikhala zosavuta komanso zosangalatsa!
Choyamba, tiyeni tikambirane za kukana dzimbiri ndi moyo wawo wonse. Ngati mukukhala m'dera la m'mphepete mwa nyanja komwe madzi a m'nyanja amakokoloka, mungafune kupewa chitsulo chopangidwa ndi galvanized steel sheet (PPGI). Zili ngati mnzanu amene sali woyenera kukhala pagombe.—Imagwira ntchito mkati mwa dziko, koma si bwino kwambiri m'mphepete mwa nyanja. Kumbali ina, pepala lopangidwa ndi galvanized aluminum-magnesium alloy sheet (PPGL) ndi pepala lopangidwa ndi galvanized aluminum-magnesium alloy sheet ndi ofanana ndi ankhondo amphamvu omwe sagonjetsedwa ndi dzimbiri. Amatha kupirira malo ovuta kwambiri, zomwe zimapangitsa kuti akhale abwino kwambiri m'madera a m'mphepete mwa nyanja ndi madera okhala ndi mankhwala. Chifukwa chake, ngati mukufuna kuti denga lanu likhale nthawi yayitali kuposa ubale wanu wakale, sankhani zipangizozi!
Tsopano, tiyeni tikambirane za zokutira. Pali mitundu inayi ikuluikulu: PE, HDP, SMP, ndi PVDF. PVDF ndi yabwino kwambiri pankhani yolimbana ndi nyengo, komanso ndi yokwera mtengo kwambiri. HDP ili pafupi kwambiri ndipo nthawi zambiri imakhala yoyenera kwambiri padenga lakunja, zomwe zimapereka mtengo wabwino. Ngati mukuganiza zogwiritsa ntchito zokutira za PE pamakoma, ganizirani kawiri! Ndizoyenera kwambiri padenga, ndipo kulimba kwake pamalo oyima kungakhale kochepa.
Ponena za makulidwe, muyenera kusankha bolodi lopangidwa ndi utoto woyenera (makulidwe ake ndi kuyambira 0.3 mm mpaka 1.2 mm) kutengera momwe ntchito ikuyendera. Ngati mtunda wa purlin ndi mamita 1.2, bolodi lopangidwa ndi 0.4 mm ndi lokwanira. Ngati mtunda uli mamita 1.5, muyenera kuwonjezera kufika pa 0.5 mm; ngati mtunda uli mamita 2.0, mutha kusankha 0.6 mm kapena ngakhale 0.8 mm. Chofunika kwambiri ndikupeza mgwirizano wabwino pakati pa mphamvu ndi kusinthasintha!
Tsopano, tiyeni tikambirane za mitundu ya matailosi a padenga. Pali mitundu ingapo, kuphatikizapo YX35-125-750, YX25-210-840, ndi YX15-225-900. Ngati mukufuna kumanga denga lalikulu, YX25-210-840 ndiye chisankho chanu chabwino kwambiri. Zili ngati bwenzi lodalirika, nthawi zonse limakhalapo pamene mukulifuna. Mitundu ina ya matailosi nayonso ndi yabwino, koma mphamvu zawo zonyamula katundu sizingakhale zazikulu ngati YX25-210-840.
Pomaliza, tiyeni tikambirane mkangano womwe wakhalapo kwa nthawi yayitali: matailosi obisika a denga motsutsana ndi matailosi ophimbidwa ndi utoto wosiyanasiyana. Matailosi obisika a denga ali ngati anthu osakhazikika m'dziko la denga.—Ndi yabwino kwambiri m'malo omwe mvula yamkuntho imabwera chifukwa imachepetsa kutuluka kwa madzi, koma ndalama zoyikira zimatha kukhala zokwera pang'ono. Matailosi ophatikizana ndi otsika mtengo, koma sangakhale olimba ngati matailosi obisika omwe amatsekedwa m'nyengo yamvula.
Mwachidule, kaya mukusankha pakati pa ma shingles a polycarbonate (PPGI), ma shingles a galvanized aluminum-magnesium (PPGL), kapena mitundu ina ya ma shingles a galvanized aluminum-magnesium, kapena ngati mukuvutika ndi kuganizira za kuphimba ndi makulidwe, Jindalai Steel Group Co., Ltd. ikhoza kukupatsani chithandizo chokwanira. Ndi chidziwitso choyenera komanso nthabwala, mutha kusankha bwino kwambiri zomwe mukufuna padenga lanu. Chifukwa chake, fufuzani molimba mtima dziko la ma shingles a polycarbonate! Denga lanu lidzakuthokozani.
