(1) Ntau yam tshwj xeeb
Cov qauv hlau rau Hulds tau muab faib ua cov qib zog raws li lawv cov khoom siv dav dav: Dav Lub zog cov qauv hlau thiab lub zog siab cov qauv hlau.
Lub Zej Zog Txheej Txheem Hlau Txheej Txheem los ntawm Tuam Tshoj Cov Koom Tes Tshwj Xeeb tau muab faib ua plaub qib ua tau zoo: A, B, thiab E; Lub High-zog Txheej Txheem Hlau Steel tau teev los ntawm Tuam Tshoj Cov Koom Tes Tshwj Xeeb tau muab faib ua peb qib ua kom muaj zog thiab ob theem zoo:

(3) Kev ceev faj rau kev xa khoom thiab kev lees txais ntawm Marine Steel Khoom:
1. Tshuaj xyuas cov ntawv pov thawj zoo:
Lub Hoobkas steel yuav tsum xa cov khoom raws li tus neeg siv cov kev xav tau thiab cov kev qhia tshwj xeeb hauv kev cog lus thiab muab daim ntawv qub zoo. Daim ntawv pov thawj yuav tsum muaj cov ntsiab lus hauv qab no:
(1) cov kev qhia tshwj xeeb;
(2) Tus lej khaws cia zoo thiab tus lej ntawv pov thawj;
(3) cua sov batch tus lej, qib kev;
(4) cov khoom siv tshuaj lom neeg thiab cov khoom siv mechanies;
(5) Daim ntawv pov thawj ntawm kev pom zoo los ntawm cov koomhaum hauv zej zog thiab kos npe ntawm tus neeg soj ntsuam.
2. Kev Ntsuas Lub Cev:
Rau kev xa tawm ntawm marine steel, lub hom phiaj lub cev yuav tsum muaj cov chaw tsim khoom logo, thiab lwm yam. Tshwj xeeb:
(1) Cov Koom Tes Pom Zoo Pom Zoo Mark;
(2) Siv cov xim pleev xim rau ncej lossis tshuaj txhuam cov cim, suav nrog cov kev tsis xws li: cov cub hluav taws xob, qhov ntev tshwj xeeb thiab dav, thiab lwm yam .;
(3) Cov tsos yog du thiab du, tsis muaj qhov tsis zoo.
