Covkub naj npawbyog ib qho ntawm cov cim tseem ceeb tshaj plaws ntawm cov kav hlau stainless.
Lub hom phiaj ntawm cov lej kub
Muab tag nrho traceability ntawm raw cov ntaub ntawv
Txuas cov yeeb nkab rau nwsMill Test Certificate (MTC)
Tso cai rau kev txheeb xyuas cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab
Txhua cov yeeb nkab uas tsim los ntawm tib lub steel melting batch yog tib lub tshav kub.
Mill Test Certificate (MTC)
CovMill Test Certificate, feem ntau yog muab raws liEN 10204 3.1 ntawv pov thawj, lees paub tias cov kav dej ua tau raws li qhov yuav tsum tau muaj tshuaj lom neeg thiab cov khoom siv tshwj xeeb.

Thib peb-Kev Tshawb Fawb thiab Ntawv Pov Thawj
Rau kev xa tawm lossis cov haujlwm tseem ceeb hauv kev lag luam, cov neeg yuav khoom feem ntau xav tau thib peb -kev tshuaj xyuas.
Cov koom haum tshuaj ntsuam xyuas muaj xws li:
SGS
TUV
BV (Bureau Veritas)
Intertek
Lloyd's Register
Cov koom haum no txheeb xyuas cov txheej txheem tsim khoom, kuaj cov txiaj ntsig, thiab ua raws li ASTM cov qauv.
