Cov txheej txheem tsim khoom rau cog trellis ncej feem ntau txawv nyob ntawm cov khoom siv -xws li xyoob, ntoo, hlau, lossis yas sib xyaws-tab sis feem ntau tuaj yeem muab faib ua ob peb theem tseem ceeb: cov khoom siv raw, shaping thiab sib sau, kho saum npoo, thiab zaum kawg sib dhos thiab tshuaj xyuas.
Rau cov ntaub ntawv hlau (xws li galvanized steel lossis aluminium alloy tubing), cov txheej txheem cuam tshuam nrog kev txiav thiab txheeb xyuas los ntawm kev qhia tshwj xeeb kom paub meej tias qhov ntev thiab txoj kab uas hla raws li kev ua haujlwm; rau cov ntaub ntawv yas lossis cov khoom sib xyaw, lub hom phiaj hloov mus rau qhov tseeb proportioning thiab blending ntawm granular raw khoom.
Hlau trellis ncej yog feem ntau zoo li tus rau hauv lawv daim ntawv kawg los ntawm cov txheej txheem xws li txiav, xuas nrig ntaus, los yog raj dabtsi yog khoov, thiab tej zaum yuav muab welded los yog interlocking cov qauv tsim. Xyoob thiab cov ntaub ntawv ntoo raug sanding, straightening, thiab kawg -tiav kom yooj yim nkag mus rau hauv av los yog txuas rau fasteners. Qee cov ntaub ntawv sib xyaw yog tsim ncaj qha rau hauv cov qauv ncej ntawm extrusion lossis molding txheej txheem los xyuas kom meej cov khoom sib xws thiab txhim khu kev ua haujlwm ntawm cov khoom loj.
Cov ncej hlau feem ntau raug kho saum npoo-xws li galvanizing, hmoov txheej, lossis daim ntawv thov pleev xim rau- txhawm rau txhim kho lawv cov xeb tiv thaiv thiab huab cua.
Xyoob thiab ntoo ncej, hloov pauv, tau txais cov tshuaj tiv thaiv -corrosive coatings kom ntev lawv lub neej kev pab nyob rau hauv ib puag ncig sab nraum zoov. Thaum ua tiav cov kev kho mob no, cov khoom sib txuas lossis cov hlua khi txuas tau raug ntsia raws li cov qauv tsim; cov ncej tom qab ntawd raug kuaj xyuas lub zog thiab kev soj ntsuam pom kom ntseeg tau tias lawv muaj kev ruaj ntseg txaus thiab ua haujlwm ntev los txhawb kev nce toj nroj tsuag.
