Rau cov rooj tog hlau dismounted, yuav tsum tau them nyiaj rau seb cov khoom sib txuas puas xoob, tawm ntawm kev txiav txim, thiab seb puas muaj qhov tshwm sim twisting; rau foldable rooj tog, yuav tsum tau saib xyuas seb lub folding qhov chaw yog hloov tau, seb lub folding cov ntsiab lus puas puas, txawm lub rivets yog khoov los yog tsis riveted, tshwj xeeb tshaj yog cov folding cov ntsiab lus ntawm cov stressed qhov chaw yuav tsum tau ruaj khov.

Cov rooj tog ntoo steel yog ib hom tshiab ntawm cov rooj tog zaum, uas siv cov ntoo ua cov khoom siv ntawm lub rooj tsavxwm thiab cov hlau ua cov pob txha. Hlau thiab ntoo rooj tog yog muab faib ua hom ruaj khov, hom disassembly thiab hom folding. Kev kho cov hlau nto muaj xws li electrostatic txau, yas hmoov txau, npib tsib xee plating, chromium plating thiab imitation kub plating.

Ntxiv nrog rau kev txiav txim siab cov khoom yuav tsum tau yuav, kev tshuaj xyuas saum npoo yuav tsum tau ua rau cov khoom yuav khoom. Xyuas seb cov electroplating puas ci thiab du, seb puas muaj qhov tsis muaj vuam ntawm qhov vuam txoj hauj lwm, seb cov xim pleev xim ntawm cov khoom siv tshuaj pleev xim electrostatic yog tag nrho thiab txawm, thiab seb puas muaj foaming; rau cov khoom ruaj khov, xyuas seb puas muaj xeb ntawm qhov sib koom ua ke, thiab seb cov hlau puas yog ntsug thiab square.

Rau cov rooj tog hlau dismounted, yuav tsum tau them nyiaj rau seb cov khoom sib txuas puas xoob, tawm ntawm kev txiav txim, thiab seb puas muaj qhov tshwm sim twisting; rau foldable rooj tog, yuav tsum tau saib xyuas seb lub folding qhov chaw yog hloov tau, seb lub folding cov ntsiab lus puas puas, txawm lub rivets yog khoov los yog tsis riveted, tshwj xeeb tshaj yog cov folding cov ntsiab lus ntawm cov stressed qhov chaw yuav tsum tau ruaj khov. Yog tias cov rooj tog raug xaiv, tsis muaj teeb meem pom tseeb hauv cov khoom saum toj no, koj tuaj yeem yuav nws yooj yim.
