2, Kev sib tsoo ua cov txiaj ntsig: tom qab sib tsoo, nws qhov chaw raug qhov tseeb tuaj yeem tswj tau ntawm qib siab.

Piv nrog lwm cov khoom siv:

Piv nrog rau tib neeg cov roj carbon hlau, lub 1215 sib tsoo tus pas nrig yooj yim tshuab yog nws qhov txiaj ntsig loj tshaj plaws.

Piv nrog lwm cov hlau sib pauv dawb, lub 1215 sib tsoo tus tsiaj muaj qee cov yam ntxwv ua tau zoo thiab cov neeg kho kom zoo dua hauv cov ntawv thov kev pabcuam.

Yuav ua li cas xaiv ib tug qauv hlau tsim nyog thaum ua Springs:

1, saib ntawm cov khoom siv:

Cov pa roj carbon ntau: nrog lub siab tawv thiab hnav tsis kam, haum rau kev txiav, kev tsim kho thiab lwm yam kev coj mus hnav;

2, saib cov specifications thiab ntau thiab tsawg:

Xyuas kom meej tias txoj kab uas hla, ntev, sib tw thiab lwm qhov ntev ntawm tus pas hlau steel ua kom tau raws li cov qauv.

3, saib ntawm qhov chaw zoo:

Xaiv cov pas nrig steel nrog cov npoo du, tsis muaj kab nrib pleb thiab tsis folding kom ntseeg tau zoo nto zoo.

4, saib ntawm cov khoom siv mechanical:

Alloy Steel: haum rau kev thauj khoom siab, siab hnav ib puag ncig ua haujlwm, xws li crusher, npo thiab lwm yam khoom siv-resistant seem.

Stainless hlau: Tsim nyog rau corrosion tsis kam thiab zoo nkauj uas yuav tsum muaj ntawm cov peev xwm ntau dua, xws li cov zog, kabmob thiab lwm yam khoom siv.

Peb cov pas nrig hlau ua los ntawm cov hlau Norline tau ua ntau yam sib txawv ntawm cov kab tsuag, xws li:
