Peb tsim ob hom hluav taws xob loj ntawm galvanized kav rau cov tsev cog khoom kev tsim kho, txhua tus muaj qhov sib txawv ntawm cov phiaj xwm:
1. Emt (hluav taws xob hlau tubing)
- Pros: Lightweight, thin-walled, and cost-effective. Yooj yim khoov, ua rau nws zoo tagnrho rau hoop lub tsev tsim.
- Cons: qis qauv txheej txheem zog thiab ib qho thinner galvanized txheej, uas tuaj yeem xeb ntau dua yog tias kos.
- Qhov zoo tshaj plaws rau: Cov Khoom Siv Hobby me me, pob nyiaj- Tus phooj ywg Hoop, thiab cov qauv ib ntus. Tsis tsim nyog rau thaj tsam nrog cov daus hnyav.
2. Cov yeeb nkab txheem yeeb
- Pros: tuab - walled, mas ruaj, thiab coated nrog lub zog galvanization txheej, ua kom muaj txiaj ntsig ntawm lub neej pabcuam. Muaj lub zog zoo dua thiab tawm tsam tiv thaiv ib puag ncig kev ntxhov siab.
- Cons: hnyav dua, kim kim, thiab nyuaj rau khoov tsis muaj cov khoom siv tshwj xeeb.
- Qhov zoo tshaj plaws rau: kev sib sau tas mus li, kev lag luam goodouses, thiab cov phiaj xwm DIY loj hauv thaj chaw muaj cov daus hnyav lossis muaj zog cua.
