Kodi ndi zinthu ziti zomwe zimakhala zolimba kwambiri pa mabenchi akunja?

Zipangizo zolimba kwambiri pa mabenchi akunja ndi Wood ndi: Oak / Chitsulo ndi: Aluminiyamu alloy / Cast aluminiyamu / Chitsulo chosapanga dzimbiri 304 pamwamba pa zinthuzo.

Aluminiyamu: mvula ndi dzuwa, motsutsana ndi kukokoloka kwa nthaka ndi mvula ndi dzuwa, kukana dzimbiri, sikophweka kuchita dzimbiri, koyenera kugwiritsidwa ntchito panja
Aluminiyamu yopangidwa ndi pulasitiki: mvula ndi dzuwa, yolimbana ndi kukokoloka kwa nthaka ndi mvula, yamphamvu kwambiri, yogwira ntchito nthawi yayitali. Yoyenera kugwiritsidwa ntchito panja.
Chitsulo chosapanga dzimbiri cha 304 chomwe chili pamwamba pake chilinso cholimba kwambiri, chokhala ndi mphamvu zopewera dzimbiri, choyenera kugwiritsidwa ntchito panja kwa nthawi yayitali
Mtengo wa Oak: kulimba: sikophweka kuwola ndi tizilombo, kapangidwe komveka bwino, kapangidwe kamphamvu, kukana dzimbiri mwamphamvu, kukhazikika kwambiri, sikophweka kusintha
Teak: yosalowa madzi/yoletsa dzimbiri/youmba/yozizira/yonyowa komanso yoletsa ming'alu, yokhala ndi nthawi yayitali yogwira ntchito
