Jaranjarada birta ah ee Caadiga ah ee Jaranjarada Bannaanka ee Sagxada Bannaanka ah ee lagu sameeyay Naqshado birta balakoonka birta ah

Ilaalada balakoonka waa qaybta ugu muhiimsan ee balakoonka, waa barxada balakoonka ee dhinaca hawada ee xarumaha badbaadada. Xadiidku guud ahaan waxay ka kooban yihiin tiirar, biro, ulo ama biro gacan, kuwaas oo loo qaybin karo biraha ubaxa ah ee maran, biraha adag iyo labadaba labadaba.
Ilaalada balakoonka ee hadda la isticmaalayo agabyo kala duwan, waxaa jira birta birta ah, xayndaabka dhagaxa, xayndaabka birta, deyrka birta ah, deyrka birta zinc, deyrka aluminiumka iyo wixii la mid ah. Kuwaas waxaa ka mid ah, ilaalinta aluminium aluminium ayaa inta badan loo isticmaalaa balakoonka qoyska.
Aluminium alloy guardrail markii ugu horeysay asal ahaan ka soo jeeda Yurub, waa dhismaha dhismaha, boosteejada, balbalada, jaranjarada iyo geesaha kale ee qaybaha xayndaabka, oo leh shaqo ilaalin ah, iyo sidoo kale waxay ciyaaraan doorka qurxinta. Horraantii todobaatanaadkii ayaa si weyn loo isticmaalay, iyo horumarinta heerarka warshadaha qaarkood, waddankeena wuxuu soo maray in ka badan 20 sano oo horumarineed. Sababtoo ah miisaanka fudud, xoogga sare, waxqabadka wanaagsan, qurxinta xooggan, cimri dhererka dhaqaalaha, wasakh-free, dib-u-warshadeynta iyo noqoshada gaadiidka dadweynaha ee Shiinaha, jardiinooyinka bulshada, dhismayaasha iyo alaabooyinka kale ee waaweyn ee xayndaabka, warshadaha xayndaabka kala duwan ee nidaamka alaabta, aluminium aluminium dayrka weli waa caan.
Faa'iidada gaarka ah ee alaabooyinka aluminiumku waa in lagu dabaqi karo noocyo kala duwan oo farsamooyinka qurxinta dusha sare ah. Dahaarka budada ah ee jilicsan ee dusha sare waxay ka difaaci kartaa raajada ultraviolet, looma baahna dayactir joogto ah ayaa lagu hayn karaa waqti dheer dhalaal dhalaalaya, tignoolajiyada qaan-gaadhka ah, cimri dhererka oo aan oxidize doonin, kala duwanaanta midabka, si weyn u wanaajinaya muuqaalka muuqaalka muuqaalka, midabka shakhsi ahaaneed. doorashooyinka si ay aluminium aluminium xayndaab waafaqsan shuruudaha qurxinta alaabta guriga oo bilaash ah oo leh ku habboonaanta si loo daboolo baahiyaha kala duwan.
