Dab tsi yog cov khoom ntawm railway ntses phaj?
Railway ntses daim hlau feem ntau yog tsim los ntawm siab - kub zoo- dov, forged, los yog cam khwb cia hlau (xws li Q235, nruab nrab, los yog siab carbon steel) los xyuas kom meej lub zog, durability, thiab tsis kam mus rau qaug zog. Rau cov ntawv tshwj xeeb, lawv tuaj yeem ua los ntawm cov khoom siv sib xyaw (fiberglass thiab resin) rau rwb thaiv tsev lossis, feem ntau, cam khwb cia hlau.
Cov ntsiab lus tseem ceeb ntawm cov khoom siv ntses ntses:
