Dub steel yeeb nkabyog cov hlau tsis muaj coated thiab tseem hu ua dub hlau.Cov xim tsaus yog los ntawm cov hlau-oxide tsim rau ntawm nws qhov chaw thaum tsim khoom.Thaum cov yeeb nkab steel yog forged, dub oxide nplai ua rau ntawm nws qhov chaw kom nws ua tiav uas pom ntawm cov yeeb nkab no.

Galvanized steel yeeb nkabyog cov hlau uas tau npog nrog ib txheej ntawm zinc hlau.Thaum lub sij hawm galvanizing, steel yog immersed nyob rau hauv ib tug molten zinc da dej, kom ntseeg tau tias ib tug tawv, uniform barrier txheej.Galvanized yeeb nkab yog them nrog cov khoom siv zinc ua kom cov yeeb nkab steel ntau tiv taus corrosion.

Qhov txawv ntawm qhov tsos
Lub hom phiaj tseem ceeb ntawm cov yeeb nkab dub yog nqa cov propane lossis cov nkev roj rau hauv cov tsev nyob thiab cov tsev lag luam.Cov yeeb nkab yog tsim los tsis muaj seam, ua rau nws zoo dua cov yeeb nkab kom nqa roj.Cov yeeb nkab dub kuj tseem siv tau rau cov tshuab hluav taws xob hluav taws xob vim tias nws muaj hluav taws kub ntau dua li cov yeeb nkab galvanized.Qhov tseem ceeb ntawm kev siv cov yeeb nkab galvanized yog nqa dej mus rau cov tsev thiab cov tsev lag luam.Cov zinc kuj tiv thaiv kev tsim cov pob zeb hauv av uas tuaj yeem txhaws cov kab dej.Galvanized yeeb nkab feem ntau yog siv los ua scaffolding thav duab vim nws tsis kam mus corrosion.

Qhov txawv ntawm cov teeb meem
Cov zinc ntawm galvanized yeeb nkab flakes tawm dhau sijhawm, txhaws cov yeeb nkab.Lub flaking tuaj yeem ua rau cov yeeb nkab tawg.Kev siv cov yeeb nkab galvanized los nqa roj tuaj yeem tsim kev phom sij.Cov yeeb nkab dub, ntawm qhov tod tes, corrodes yooj yim dua li cov yeeb nkab galvanized thiab tso cai rau cov zaub mov los ntawm dej los tsim hauv nws.
