Txoj kev tsim khoom:
Txoj kev tsim khoom yuav tsum yog raws li nram no:
a) Square steel kav yog tsim los ntawm kev tsim cov welded steel kav (los ntawm hluav taws xob tsis kam vuam, forge welding los yog tsis siv neeg arc vuam) los yog seamless steel kav rau hauv cov duab square, los yog los ntawm kev tsim cov hlau strips rau hauv square cross -section los yog ib khub ntawm cov kab hla ntu. , manufactured los ntawm nruam hluav taws xob kuj welding los yog tsis siv neeg arc vuam.
b) Square steel kav yuav tsum ua raws li kev tsim thiab ib txwm tsis kho cua sov.
c) Square steel kav tej zaum yuav raug tsim siv galvanized steel los yog galvanized steel strips yog thov los ntawm cov neeg siv khoom. Tsis tas li ntawd, thaum tsim cov kav dej square steel siv cov ntawv hlau plated lossis strips, nws yog qhov tsim nyog siv hom plating thiab txheej hnyav qhia hauv Annex A.
d) Cov yeeb nkab kawg yuav tsum yog qhov xaus tshwj tsis yog tias tau teev tseg. Txawm li cas los xij, yog tias tus neeg txiav txim qhia qhov kawg ntawm bevel, cov duab yuav tsum yog raws li qhov kev pom zoo ntawm ob tog rau kev xa khoom.
Raws li cov chaw tsim khoom thiab lub Hoobkas, BRISK STEEL muab JIS G3466 Square thiab Rectangular Pipe hauv qib STKR 400 thiab STKR 490
