Lawv tuaj yeem muab cov ntaub ntawv raug ntau dua hais txog cov thickness ntau thiab cov kev cai thicknesses uas yuav ua tau raws li koj cov kev xav tau tshwj xeeb. Qhov kev xaiv ntawm thickness yog nyob ntawm tej yam xws li cov txheej txheem yuav tsum tau, load-bearing muaj peev xwm, corrosion kuj, thiab fabrication txiav txim siab ntawm lub npaj daim ntawv thov. Cov phaj tuab tuab tuaj yeem ua kom muaj zog ntxiv, thaum cov phaj nyias nyias yuav nyiam dua rau kev txo qhov hnyav lossis kev tsim tshwj xeeb. Nws tseem tsim nyog sau cia tias A633GrD steel tuaj yeem ua ntau hom, xws li daim hlau, coils, lossis lwm yam duab, thiab cov kev xaiv tuab tuaj yeem sib txawv raws li.
Tsis tas li ntawd, qee cov qauv lossis cov kev qhia tshwj xeeb yuav txiav txim siab yam tsawg kawg nkaus lossis siab tshaj qhov yuav tsum tau ua rau A633GrD steel. Txhawm rau kom muaj cov thickness uas xav tau thiab ua kom tau raws li qhov project specifications, nws raug nquahu kom sib txuas lus koj cov kev xav tau thaum ntxov nrog cov neeg xa khoom thiab sib tham txog cov kev cai thickness xaiv lossis kev txwv. Qhov no yuav pab xyuas kom meej tias A633GrD steel koj tau txais ua tau raws li koj qhov kev xav tau thiab cov lus qhia tshwj xeeb.
Peb lub Hoobkas
Qinhuangdao Aotong tau tsim muaj nyob rau hauv 2004, nws yog ib tug geoup tswj tuam txhab uas muag nrog kev sau ntawm kev lag luam, hlau txuas ntxiv ua thiab warehousing logistics .Lub peb lub lag luam loj muaj xws li Aotong hlau chaw thiab lub Aotong logistics chaw .Lub Hoobkas npog thaj tsam ntawm 202000 square. meters.Lub tuam txhab tau tsim Chenggang Wuyang thiab lwm yam loj steel mills thiab cov tub lag luam thoob plaws lub teb chaws.Cov khoom tseem ceeb muaj xws li nruab nrab thiab hnyav steel daim hlau, kub dov coils, txias dov pickled daim hlau, profiles tsev cov ntaub ntawv, thiab lwm yam., nrog txhua xyoo muag khoom ntawm ntau tshaj. Ntau tshaj 300 txhiab tons.Ntxiv rau kev pabcuam ntau tus neeg siv khoom hauv tsev thiab cov haujlwm loj thiab nruab nrab, cov khoom raug xa tawm mus rau Tebchaws Europe, South America thiab Southeast Asia.
