Magacaabista dahaarka waa ereyga meesha ugu yar ee saddex-laaban, wadarta labada dhinac ee daahan miisaanka [cufka] lagu cayimay.Sababtoo ah doorsoomayaal badan iyo xaalado isbeddelaya kuwaas oo sifo leh xadhkaha dahaarka kulul ee joogtada ah, dahaarka zinc ama zinc-birta dahaarka mar walba si siman uma kala qaybsana labada sagxood ee xaashida daboolan;sidoo kale mar walba si siman looma qaybiyo gees ilaa gees.Si kastaba ha ahaatee, miisaanka ugu yar ee saddex-geesoodka ah ee celceliska miisaanka (cufka) dhinac kasta waa inuusan ka yarayn 40 % ee shuruudaha hal-dhibcood.
Maaddaama ay tahay xaqiiqo la aasaasay oo ah in caabbinta daxalka atmospheric ee zinc ama alaabta xaashida dahaarka leh ee zinc-birta ay tahay shaqo toos ah oo dhumucdiisuna tahay daahan (miisaanka (miisaan)), xulashada naqshadaha dahaarka khafiifka ah (fudud) waxay dhalin doontaa ku dhawaad toosan. hoos u dhaca waxqabadka daxalka.Tusaale ahaan, dahaarka galvanized ee culus ayaa si ku filan u sameeya muujinta jawiga geesinimada leh halka dahaarka khafiifka ah inta badan lagu dahaadhay rinji ama dahaar la mid ah si loo kordhiyo caabbinta daxalka.Xidhiidhkan dartiis, alaabada sidda bayaanka "buuxiya ASTM A653/A653 Shuruudaha" waa inay sidoo kale qeexaan calaamadda dahaarka gaarka ah.
Ugu yaraan macnaheedu maaha in aanay jirin shuruudo la dejiyay ee imtixaanada saddex-la- iyo hal-dhibcood.
