Sm490ya / yb h - Beams tau siv dav hauv kev tsim kho thiab engineering, thiab txhim khu kev qha log} kev coj tus kabmob. Lawv cov khoom siv muaj zog thiab ntau yam sib txawv ua rau lawv zoo tagnrho rau:
Txuas hniav thiab txoj kev loj tsheb loj
Girders Main, hla kev hla, thiab lawj kev txhawb nqa muaj peev xwm tuav lub tsheb hnyav thiab kev ntxhov siab ib puag ncig.
Muaj Thiab Khoom Sectors
Cov qauv coj ua rau cov chaw tsim khoom, chaw khaws ntaub ntawv, offshore roj platform, thiab tshuaj lom neeg, tau txiaj ntsig los ntawm cov hlau lub zog ntawm lub zog thiab
Kev Cuam Tshuam.
Tubrog Nkoj thiab Chaw Nres Nkoj
Docks, ntim cranes, thiab cov ntug dej hiav txwv raug rau cov ntsev tsuag thiab cov av noo, qhov chaw ua rau corrosion kuj yog qhov tseem ceeb.
Lub tuam tsev thiab cov qauv tsim qauv
Txhua, kab teeb, thiab sab nraum zoov façades uas yuav tsum tau txhawb nqa ruaj khov thiab ntev}}} lub sij hawm kev ua tau zoo hauv atmospheric.
Cov cuab yeej hnyav thiab tsheb thauj mus los
Thav ntawv, chassis, thiab platforms rau tshuab, tsheb, thiab cov tsheb ciav hlau uas xav tau cov kabmob muaj zog thiab cov qauv ruaj khov.
