Cov khoom siv feem ntau siv hauv cov hlab ntsha siab yog steel. Hlau yog muaj zog, ruaj, thiab pheej yig, ua rau nws haum rau siv nyob rau hauv ib tug ntau yam ntawm kev siv lub nkoj siab. Nws muaj lub zog tensile zoo thiab tuaj yeem tiv taus qhov kub thiab txias. Steel siab hlab ntsha kuj yog ib qho yooj yim los tsim thiab kho, muab cov nqi ntxiv.
Txawm li cas los xij, lwm cov ntaub ntawv kuj tseem siv rau hauv kev tsim cov hlab ntsha siab, nyob ntawm seb cov ntawv thov tshwj xeeb thiab cov neeg siv yuav tsum tau ua. Aluminium, fiberglass, thiab composites yog lwm txoj hauv kev rau cov hlau, muab cov txiaj ntsig sib txawv xws li qhov hnyav dua, tiv thaiv corrosion, lossis qis dua.
Aluminium yog lub teeb yuag thiab corrosion-resistant, ua rau nws haum rau sab nraum zoov lossis marine daim ntaub ntawv qhov twg corrosion kuj tseem ceeb. Txawm li cas los xij, aluminium muaj zog tensile qis dua steel thiab kim dua.
Fiberglass thiab composites feem ntau yog siv rau lawv cov kev tiv thaiv corrosion, tsis tshua muaj hnyav, thiab zoo thermal rwb thaiv tsev zog. Lawv tsim nyog rau cov ntawv thov uas qhov hnyav thiab corrosion kuj tseem ceeb dua tus nqi. Txawm li cas los xij, fiberglass thiab composites tej zaum yuav tsis haum rau kev siv high-pressure los yog huab cua kub.
Hauv kev xaus, steel tseem yog cov khoom siv tshaj plaws rau cov hlab ntsha vim nws lub zog, durability, thiab nqi-zoo. Txawm li cas los xij, lwm cov ntaub ntawv xws li txhuas, fiberglass, thiab cov khoom sib xyaw kuj tseem siv rau hauv cov ntawv thov tshwj xeeb uas lawv cov khoom tshwj xeeb muab qhov zoo dua cov hlau. Qhov kev xaiv ntawm cov khoom yog nyob ntawm daim ntawv thov tshwj xeeb, cov neeg siv khoom xav tau, thiab cov nqi txiav txim siab.
