Hais txog qhov ntev, BV E500 Marine Steel daim hlau muaj nyob rau hauv ntau thicknesses, dav, thiab ntev kom haum rau ntau yam kev tsim kho cov tub rog marine. Qhov kev hloov pauv no tso cai rau kev siv cov khoom siv tau zoo thiab txo cov khoom siv thaum ua cov txheej txheem kev tsim kho.
Kev Cuam Tshuam yog qhov tseem ceeb ntawm kev tswj hwm cov txheej txheem zoo rau cov phiaj hlau no. Qhov kev ntsuas no cuam tshuam nrog cov phiaj rau tsawg - kub cuam tshuam cov kev cuam tshuam rau lawv cov kev tiv thaiv kom tawg thiab brittleness. Qhov kev cuam tshuam zoo heev ntawm BV E500 Steel daim txheem ua kom lawv txoj kev ntseeg tau hauv qhov chaw txias.
Thawj cov ntawv thov ntawm BV E500 Steel daim phiaj yog nyob rau hauv kev tsim kho cov nkoj, sab nrauv platform, thiab lwm cov tub rog marine. Cov phiaj hlau hlau no tau siv dav hauv Hulls, decks, thiab lwm yam tseem ceeb ntawm cov txheej txheem uas muaj zog thiab corrosion tsis kam yog qhov tseem ceeb.
