Saw txuas laj kab (tseem hu ua xaim hlau, xov hlau hlua laj kab, laj kab xov laj kab hlau, laj kab thaiv, cua daj cua dub laj kab, lossis nag xob nag cua)
pob zeb diamond-mesh laj kab) yog ib hom xov laj kab uas feem ntau yog tsim los ntawm galvanized lossis PVC-coated steel hlau xaim. Cov xov hlau khiav
ntsug thiab yog khoov rau hauv tus qauv zig-zag kom txhua tus "zig" hooks nrog cov xaim tam sim ntawm ib sab thiab txhua "zag"
nrog lub xaim tam sim ntawm lwm yam. Qhov no tsim cov yam ntxwv pob zeb diamond yam ntxwv pom hauv hom laj kab no.
Saw txuas laj kab, yog cov laj kab nthuav dav, siv cov xov xov steel hlau los ua lub vaj huam sib luag, nws tau siv dav hauv txhua qhov chaw.
Vim tias cov ntawv thov sib txawv, nws muaj nyob hauv ntau cov xov hlau thiab cov ntxaij ntau thiab tsawg. Saw hlau laj kab muaj ob yam

Kho deg:
1.Hov tsis suav galvanized:
Lub laj kab muaj cov qauv galvanized los tiv thaiv xeb, hauv cov txheej txheem galvanization txheej txheej ntawm zinc yog tsim rau saum npoo
hlau. Cov xim no tiv thaiv cov hlau tsis zoo los tiv thaiv xeb.
2.Galvanized thiab PVC caoated:
Galvanized vaj huam sib luag laj kab tshuab tuaj yeem yog cov hmoov xaim xim cov xim uas koj xaiv. Hmoov txheej txhim kho kom zoo
cov tshuaj tiv thaiv los tiv thaiv kev tiv thaiv los ntawm kev tiv thaiv oxidation ntawm zinc, tshuav rau qhov uas peb cov fencing fwm khaws cia lawv zoo nkauj
zoo los ntawm ntev dua.
