STE 500 steel phaj

Choj structural steel DIN StE500 steel phaj yog tsuas yog siv los tsim riveted thiab bolted choj steel qauv, xws li txoj kev loj choj, railway choj, hiav txwv choj, overpasses, viaducts thiab loj mechanical overhead cranes. DIN StE500 steel phaj, E qib choj hlau yog tsim rau choj cov qauv qhov chaw uas nyuaj thiab hnyav nyob rau hauv qis kub thiab txias ib puag ncig los yog dais dynamic loads thiab complex thiab hnyav quab yuam tej yam kev mob.
