Cov ntawv thov ntawm Astm A709 Qib 50W Weatherhing Steel Kav Hlau
1. Choj moj khaum thiab thauj khoom -} cov kabmob kem
A709 Gr.50W Weather Cov Hluav Taws Xob Hlau Version yog dav siv nyob rau hauv Choj Ua Haujlwm, Truss cov tswv cuab, thiab thauj khoom {{2} {}} belks} kem cov kabmob. Lawv cov zaub mov siab muaj zog thiab nkees heev ua rau lawv zoo tshaj plaws rau ntev- span choj txuas ntxiv thiab nce cov neeg sib tw. Lub ntuj Oxide PATINE tsim nyob rau saum npoo tshem tawm qhov xav tau kev pleev xim, txo qhov ntev}} lub sijhawm tu cov nqi. Hauv cov cheeb tsam ntug dej hiav txwv zoo li Thaib, cov hlau no ua kom muaj kev pabcuam ntev ntev txawm tias nyob rau hauv cov ntsev {8} laden cua kis.
2. Kev loj thiab kev tsheb ciav hlau tiv thaiv
Cov kav dej tseem tau thov rau hauv kev thaiv kev nyab xeeb thiab cov neeg saib xyuas txhawb nqa cov kev loj thiab kev tsheb nqaj hlau. Ua tsaug rau lawv cov kev cuam tshuam zoo tshaj plaws, A709 Gr.50w kav dej tuaj yeem tiv thaiv lub tsheb sib tsoo thiab kev sib tsoo tsheb. Cov huab cua hlau ua tiav kev ua tiav kev ua kom zoo nkauj, uas ua rau nws cov khoom siv nyob ib puag ncig rau cov phiaj xwm niaj hnub qhia txog kev nyab xeeb thiab kev sib raug zoo thiab pom kev.
3. Kev Kho Kom Zoo Nkauj Archtres Façades
Kws Tsim Qauv thiab cov tsim qauv xaiv A709 Gr.50W rau lub tsev ua si, thiab cov claddings sab nraum zoov vim nws tus nplua nuj muaj rust} zoo li tsos thiab muaj kev sib tw. Sij hawm dhau los, cov hlau tsim cov khaub ncaws hnav zoo li qub, tiv thaiv Patina txheej uas tau hloov xim huab cua, muab cov khoom muaj sia nyob uas yuav tsum tsis muaj txheej lossis rov pleev xim. Nws sib txuas ua haujlwm thiab kev pom zoo rau kev pom zoo, haum rau cov tsev pej xeem, tsev cia puav pheej, thiab cov toj roob hauv pes duab nruab.
4. Kev tsim hluav taws xob txhawb nqa thiab cov nqus dej tshuab
Hauv kev siv cov nroj tsuag, cov kav dej no tau siv los ua kev txhawb nqa rau kev kis lub raj xa dej, tso kua rau kom tsis txhob muaj pa tawm, thiab nqi hluav taws xob. Cov khoom siv zoo tshaj plaws - {{2} Txoj kev nyhav nti thiab xeb kev ua tau ruaj khov nyob rau hauv varying siab thiab ntsuas kub. A709 GR.50W tswj cov seem seem ruaj khov thiab thauj khoom - kev xaiv muaj peev xwm xaiv tshuaj lom neeg, cov chaw kho kom huv.
5. Chaw nres nkoj thiab marine tsev
