Dziwani zambiri za kukula kwake
Pamwamba Wamba
Pamwamba pa Galvanized(kukhuthala kwa galvanizing ya hot-dip ≥ 85μm, nthawi ya moyo wa zaka 15-20),
Nyumba Zachitsulo Zopangira Kapangidwe: Gwiritsani ntchito m'mizere, matabwa ndi mafelemu omwe amamanga m'nyumba zamalonda ndi zogona.
Mafakitale ndi Malo Osungiramo Zinthu: Nyumba zomangira nsalu zamafakitale, zida zopangira zinthu ndi zina zambiri.
Milatho ndi Zomangamanga: Kugwiritsidwa ntchito pa misewu ikuluikulu, milatho ya anthu oyenda pansi kapena mapulojekiti omanga nyumba.
Kapangidwe ka Nyumba Zazitali Kwambiri & Zazikulu: Akulimbikitsidwa ku mabwalo amasewera, ma eyapoti, malo owonetsera zinthu ndi nyumba zina zazikulu.
Chithandizo cha Makina: Chifukwa cha kukhazikika kwake, ndi koyenera kugwiritsa ntchito makina a mafakitale ndi nsanja zogwirira ntchito.
Kapangidwe KokonzedweratuKawirikawiri amagwiritsidwa ntchito mu dongosolo la zomangamanga zachitsulo chokhazikika.
1) Ali ndi maofesi a nthambi ku United States ndi Guatemala, ndipo angapereke chithandizo cha Chisipanishi.
2) Mtengo wa matani 5000 H uli m'nyumba yosungiramo katundu.
3) Kuwunika bwino khalidwe la katunduyo kumachitika asanatuluke mufakitale.
Kuphimba pansi: Kuti tipewe kukanda pamwamba kapena "zizindikiro zotsekeka" za zingwe, gawo laling'ono la rabara kapena thovu lolemera limayikidwa pamalo olumikizirana a matabwa ndi malo omangira.
Kuletsa Kutsetsereka: Kulumikizana kwa matabwa mu mtolo sikuyenera kusokonezedwa. Pa kutalika kwaufupi, kulumikiza mizere iwiri ndikokwanira, pazidutswa zazitali, malo owonjezera othandizira amaletsa kupindika ndi/kapena kutsetsereka.
Malo Osungira/Kuyendera M'nyumbaNgati chitsulocho chapakidwa kale kapena chamalizidwa, chiyenera kukulungidwa mu chotchinga cha chinyezi, monga filimu ya pulasitiki kapena pepala la kraft.
Mayendedwe akunja: Pa sitima, kunja kwa nyanja, mayendedwe akuluakulu, ma tarpaulin osalowa madzi okhala ndi zigawo ziwiri amapezeka ngati muyezo kuti asalowe m'malo onyowa komanso amchere m'nyanja.
Q1: Kodi Q355B ikutsatira miyezo iti?
A:Q355B ikutsatira muyezo wa ku China wa GB/T 1591 ndipo ikukwaniritsa zofunikira za chitsulo chapadziko lonse lapansi.
Q2: Kodi mungapereke Ziphaso Zoyesera za Mill (MTC)?
A:Inde, Zikalata Zoyesera za Mill zimaperekedwa pa gulu lililonse. Kuwunika kwa chipani chachitatu monga SGS kapena BV kumapezekanso mukapempha.
Q3: Kodi njira zanu zopakira ndi zotumizira ndi ziti?
A:Matabwa a H amamangidwa ndi zingwe zachitsulo, zothandizidwa ndi zotchingira matabwa, ndipo zimakulungidwa kuti zisawonongeke. Kutumiza kumapezeka kudzera mu chidebe kapena chombo chachikulu chokhala ndi malamulo a FOB, CFR, CIF, kapena EXW.
Q4: Kodi nthawi yoperekera ndi iti?
A:Katundu: Masiku 5–10
Kupanga: Masiku 15-30 kutengera kuchuluka kwa oda ndi zomwe zafotokozedwa
Q5: Kodi mumathandizira kusintha kwa zinthu?
A:Inde, timathandizira miyeso, kutalika, ndi kupanga zinthu pogwiritsa ntchito mapulojekiti malinga ndi zojambula ndi zofunikira.
