Hlau grating yog ib daim phiaj-zoo li cov khoom siv hlau tsim los ntawm kev vuam lossis siab- kaw cov kab tiaj tiaj thiab cov hlaws (xws li cov kab sib tw twisted) ntawm cov ntu tshwj xeeb. Nws cov yam ntxwv tseem ceeb suav nrog lub zog siab thiab thauj khoom-cov kabmob muaj peev xwm, qhov cua zoo heev, lub teeb kis tau tus mob, thiab cov dej ntws tawm, kev ua haujlwm zoo tshaj - plam kev ua haujlwm, kev tiv thaiv corrosion, thiab yooj yim ntawm installation thiab txij nkawm.
Nws yog feem ntau siv nyob rau hauv kev lag luam thiab kev tsim kho sectors, ua haujlwm steel qauv platform decking, taug kev, stair treads, trench npog, tso dej grate, nkag mus rau hauv txoj kev hauv tsev, tu platforms, thiab cov ntawv zoo sib xws.
Raws li cov txheej txheem tsim khoom, steel grating tuaj yeem muab faib ua siab -welded grating, swage-lock grating, thiab composite grating. Hais txog cov khoom, nws yog categorized rau carbon steel (feem ntau kub-dip galvanized) thiab stainless hlau (xws li Qib 304 los yog 316). Raws li cov duab ntawm cov tiaj tiaj, nws tau muab faib ua hom tiaj tiaj, hom serrated (anti-slip), thiab kuv-bar hom.
Nws cov txheej txheem tsim khoom yuav tsum ua raws li cov qauv kev lag luam, xws li Tuam Tshoj tus YB / T4001 series, Tebchaws Asmeskas 'ANSI / NAAMM (MBG531) cov qauv, thiab United Kingdom's BS4592 cov qauv.
Txhawm rau kom muaj kev nyab xeeb, steel grating yuav tsum tau muab khi kom ruaj ntseg thaum lub sij hawm installation siv txoj kev xws li vuam los yog tshwj xeeb mounting clips. Tsim loads sib txawv nyob ntawm seb qhov kev thov tshwj xeeb scenario; Piv txwv li, kev lag luam platforms feem ntau yog tsim los rau ib qho kev faib tawm ntawm 2 kN / m², kev kho lub platform rau 4 kN / m², thiab kev taug kev rau kev thauj khoom xws li 3.0 kN / m² txog 7.5 kN / m², nyob ntawm cov neeg taug kev ceev.
