Choj hlau tshwj xeeb yog siv los tsim kev tsheb ciav hlau lossis kev loj choj. Nangang choj steel nrog kev lag luam innovation pace, tsom mus rau txoj kev loj hlob ntawm ntsuab, tsis tshua muaj carbon, nce peev hauv choj steel, nyob rau hauv ib tug tshiab tiam ntawm kev ua tau zoo choj steel kev tshawb fawb thiab kev loj hlob thiab daim ntawv thov, cov khoom ceev ceev hloov khoom dua tshiab, tau tam sim no tsim Q 345. Q-Q500q, huab cua tsis kam (xws li tsis muaj txheej) choj steel series (nrog rau huab cua kev twb kev txuas, vuam hlau), Txuas hniav nrog stainless hlau dov composite phaj thiab lwm yam series, tag nrho specifications, ntau pawg ntawm batch mov muaj peev xwm. Nangang choj thiab steel daim ntawv thov cov haujlwm suav nrog Hutong Choj, Pingtan Strait Choj, New Bay Choj hauv San Francisco, Zangmu Choj Project, Meishan Railway Tshwj Xeeb Project, Lianzhen Railway Wushan Yangtze River Highway thiab Railway Choj Project, Hangzhou-Shao-Tai Railway Jiaojiang Choj, lwm.
Cov hlau phaj rau cov qauv choj tuaj yeem tsim thiab xa tawm raws li cov qauv tsim thiab cov kev cai ntawm GB / T714, ASTM A709, JIS G3106, TB10002.2; nrog kub dov / tswj dov, ignition dov, ignition dov, kev kho kom zoo, TMCP / TMCP + tempering. Qhov siab tshaj plaws ib qho hnyav tuaj yeem ncav cuag 4 tons. Cov khoom lag luam muaj kev ua haujlwm zoo thiab kev ua haujlwm vuam, uas tuaj yeem ua tau raws li kev tsim kho ntawm txoj kev loj choj, railway choj thiab railway choj, tshwj xeeb tshaj yog haum rau loj-span high-qib choj engineering daim ntawv thov.
