Kev txiav txim siab cov ntsiab lus rau qhov zoo ntawm lub teeb steel keels:
1. High -} Zoo Steel Sawb;
2. Lub teeb Steel Keel ua cov khoom siv;
3. Thickness sib txawv ntawm cov hlau txaij;
4. Ob -} sided galvanizing kev them nqi ntawm lub teeb steel keel;
5. Cov tsos zoo;
6. Kev tswj hwm tsis zoo los ntawm Keel Chaw Tsim Tshuaj.
Cov tsos zoo: Lub teeb Steel keels yuav tsum yog tus, nrog cov npoo ntse thiab cov ces kaum. Kev txiav yuav tsum muaj kev ywj pheej thiab deformation uas tuaj yeem cuam tshuam kev ua haujlwm. Lub galvanized txheej yuav tsum muaj qhov tsis xws luag xws li teeling, o, thiab ntug. Cov tsos tshuaj ntsuam xyuas tau zoo yuav tsum tau ua visually ntawm qhov deb ntawm 0.5 m ntawm cov khoom hauv lub teeb ci ntsa iab.
Qhov saum npoo ntawm lub teeb steel keel yuav tsum yog galvanized rau xeb tiv thaiv. Ob npaug -} sidded galvanizing kev pab them nqi rau high cov khoom lag luam zoo yuav tsum tsis pub tsawg tshaj li 120 g / m².
