Steel grating-tseem hu ua steel daim phiaj phaj- yog qhib- daim phiaj steel qauv tsim los ntawm orthogonal ua ke ntawm kev thauj khoom-cov kabmob tiaj tus thiab cov hlaws tau teem rau ntawm lub sijhawm tshwj xeeb. Feem ntau, cov crossbars muaj qhov sib tw square steel tuav, uas tau ruaj khov rau hauv qhov chaw los ntawm kev vuam lossis nias - txheej txheem kaw. Qhov kev teeb tsa tshwj xeeb no tsim cov qauv ntawm cov phiaj xwm square nyob rau hauv grating, endowing nws nrog ib tug tswv tsev ntawm superior kev ua tau zoo yam ntxwv.
Hauv paus, lub load-cov kabmob tiaj tus feem ntau dais ntsug loads thov los ntawm saum toj no thiab faib lawv mus rau crossbars; kev sib cuam tshuam ntawm ob lub ntsiab lus tsim kom muaj kev ruaj ntseg txhua yam qauv uas ua rau cov hlau grating txhawb nqa qhov hnyav yam tsis muaj deformation. Piv txwv li, nyob rau hauv kev lag luam platforms, kev sib xyaw hnyav ntawm cov neeg ua haujlwm thiab cov khoom siv tau muab faib ua tus sib npaug ntawm cov grating nto; ntawm no, lub load-cov kabmob tiaj tus ua haujlwm zoo li "spins," thaum lub crossbars ua haujlwm zoo li "skeleton," ua haujlwm hauv kev sib koom ua ke los txhawb tag nrho cov qauv platform.
Hais txog cov txheej txheem tsim khoom, ob txoj hauv kev tseem ceeb yog kev vuam siab thiab nias - xauv. Siab-welded steel grating yog tsim los siv cov khoom siv hydraulic tsis siv neeg vuam (feem ntau nyob ntawm 200 tons) los vuam cov khoom thauj -cov kabmob tiaj tus thiab cov hlaws hla- teeb tsa hauv cov qauv kab sib luag- rau hauv lub vaj huam sib luag; lub vaj huam sib luag no tau dhau los ua cov txheej txheem tom ntej xws li txiav, txiav, thiab edging kom ua tiav cov khoom tiav. Hloov pauv, nias-locked steel grating yog tsim los ntawm kev siv lub zog los yuam cov crossbars ua ntej- txiav cov qhov nyob rau hauv cov load{10}}cov kabmob tiaj tus, yog li tsim kom muaj kev ruaj ntseg ntawm cov khoom sib txuas ntawm cov khoom.
Hais txog cov ntaub ntawv, feem ntau xaiv yog carbon steel thiab stainless hlau. Carbon steel grating offers an affordable solution and is frequently subjected to hot-dip galvanizing-a process that forms a dense, protective zinc layer on the surface to prevent oxidation and rust-making it suitable for use in most general environments. Stainless hlau grating- feem ntau yog tsim los ntawm qib xws li 304 lossis 316-inherently muaj qhov tshwj xeeb corrosion tsis kam vim muaj cov ntsiab lus alloying xws li chromium thiab npib tsib xee; yog li ntawd, nws yog dav siv nyob rau hauv ib puag ncig corrosive heev, xws li cov nroj tsuag tshuaj thiab kev tsim kho ntug dej hiav txwv.
