zais los ntawm kev pom tab sis qhov tseem ceeb rau kev ncaj ncees, cov khoom lag luam yog qhov tseem ceeb hauv kev sib txuas uas koom nrog ob daim ntawm lub qhov rais lossis qhov rooj qhov rooj profile ntawm 90-degree kaum sab xis. Qhov kev txhaj tshuaj no- molded yas los yog tuag-cam khwb cia hlau tivthaiv yog muab tso rau hauv lub hollow kawg ntawm ob profile tuav thiab ruaj ntseg nrog screws, tsim lub literal productstone ntawm tag nrho cov thav duab sib dhos. Nws lub luag haujlwm thawj zaug thiab pom tseeb tshaj plaws yog kev sib txuas yooj yim, hloov tus kheej ntev ntawm cov hlau mus rau hauv cov duab plaub lossis square qauv.

Qhov tseem ceeb ntawm qhov siab - zoo, txawm li cas los xij, yog nyob rau hauv nws lub peev xwm los muab kev ruaj khov thiab ntev - lub sij hawm ruaj khov. Yog tsis muaj nws, lub hollow aluminium thav duab yuav ua rau twisting, racking, thiab tuaj xoob ntawm cov pob qij txha hauv kev ntxhov siab. Cov khoom muaj zog nrog ntev mounting tangs tsim muaj zog, triangulated reinforcement ntawm qhov sib koom ua ke, zoo tiv thaiv cov rog thiab ua kom cov thav duab tseem zoo kawg nkaus square thiab dimensionally ruaj khov thoob plaws hauv nws lub neej. Qhov squareness no yog qhov tseem ceeb rau kev ua haujlwm du ntawm zawv zawg Cheebtsam thiab kom tswj tau qhov sib txuas sib txuas. Cov hom muaj xws li cov qauv yas rau cov khoom sib dua-cov ntxaij vab tshaus thiab hnyav- cov khoom siv hlau (feem ntau yog txhuas lossis zinc alloy) rau lub qhov rooj loj loj lossis cov ntxaij vab tshaus ruaj ntseg, qhov siab tshaj plaws yog tsis yog - sib tham. Lub kaum sab xis yog tus saib xyuas tsis pom ntawm koj lub vijtsam duab, lub zog, thiab kev ua haujlwm.
