Kutentha kwambiri kanasonkhezereka ophatikizidwa mbali(zidutswa zopangidwa kale) ndizinthu zomwe zimayikidwiratu (kuyikidwa m'manda) muntchito zobisika. Ndiwo zigawo zikuluzikulu ndi zovekera zomwe zimayikidwa panthawi yopanga ndipo zimagwiritsidwa ntchito pophatikizana mukamaika superstructure. Pambuyo kutentha galvanizing pamwamba chithandizo, zotsatira antirust zimatheka. Pofuna kukhazikitsa ndikukhazikitsa maziko azida zakunja zakunja. Mbali zambiri zophatikizidwa ndizopangidwa ndi chitsulo. Kapangidwe kake, ma bolt amaphatikizidwa ndi kapangidwe kake nthawi imodzi, ndipo ulusi womwe umayikidwa pambali kumtunda umagwiritsidwa ntchito kukonza zinthuzo ndikuchita nawo kulumikizana ndi kukonza. Sizachilendo kusungira ma bolts azida. Malinga ndi zojambulira zakusinthira-muyeso wokhazikika-bulaketi-ma bolts, magawo ophatikizidwa ndi kuyesanso kwakanthawi kokhazikika ndikumaliza.
