1. Core Performance for High -Kev siv tsheb
Slip Resistance Design: Ntxiv cov ntaub ntawv zoo nkauj (knurling, pob zeb diamond phaj qauv, lossis tsa cov lugs) rau saum toj kawg nkaus - cov yam ntxwv no tsim kev sib txhuam thiab tso dej / av nkos, txo qis kev pheej hmoo hauv qhov chaw ntub dej lossis tsis khoom. Tsis txhob ua kom tiav uas ua rau muaj kev phom sij thaum damp.
Cov qauv siv tau ntev: Siv8-12 hli tuab kub-rolled weathering steelrau load-cov kabmob treads; qib no tiv taus cov tsheb loj, lub log tsheb, thiab sab nraum zoov tsis muaj warping lossis khoov. Txhim kho cov npoo nrog rounded steel strips tiv thaiv chipping thiab kev ntxhov siab corrosion.
Tus kheej -Kev Tiv Thaiv Patina: Cov tuab tuab tuab- xim av patina tsim nyob rau hauv 6-12 lub hlis, tiv thaiv cov hlau los ntawm corrosion txawm nyob rau hauv cov av ntub los yog cov ntug hiav txwv dej- tshem tawm qhov xav tau kev pleev xim ntau zaus los yog txheej txheej.
2. Fabrication & Installation Cov kev coj ua zoo tshaj plaws
Nto Prep: Sandblast treads tshem tawm zeb nplai thiab cov kab mob, tsim kom muaj ib qho kev ntxhib los mos (Ra 3-5 μm) uas txhawb nqa kev loj hlob ntawm patina thiab txhim kho plam tsis kam. Degrease nrog isopropyl cawv kom tsis txhob muaj roj residue buildup.
Vuam & Tiav: Weld nrog weathering steel-cov electrodes tshwj xeeb (xws li, E7018-W) thiab grind weld seams smooth kom tiv thaiv tsis sib xws patina thiab tripping txaus ntshai. Hloov tag nrho cov npoo ntse los txhim kho kev nyab xeeb thiab txo cov ntsiab lus kev ntxhov siab.
Installation Gap: Cia qhov sib txawv ntawm 2-3 hli ntawm cov treads thiab risers kom ntws dej, tiv thaiv kev ya raws uas ua rau muaj kev cuam tshuam hauv zos. Thauj tog rau nkoj treads ruaj ntseg rau tus ntaiv ncej kom tsis txhob hloov nyob rau hauv hnyav siv.
3. Tsawg-Kev Kho Mob
Thawj Huab Cua (6-12 Lub Hlis): Yaug txhua hli nrog tsawg- dej siab kom tshem tawm cov plua plav thiab cov khib nyiab; zam cov tshuaj ntxuav acidic uas ua rau cov patina tsim.
Ntev -Tsev Kho Mob: Ntxuav 1-2 zaug ib xyoos ib zaug thaum lub patina stabilizes. Rau cov chaw ntug dej hiav txwv lossis chaw ua lag luam, siv lub pob tshab fluorocarbon sealant txhawm rau txhawm rau txhawm rau tiv thaiv thiab ua rau lub neej ntev. Cov khawb me me yuav ua rau nws tus kheej- kho raws li kev hloov kho patina.
