This hot-rolled I-beam, profile No. 19, is a structural steel section manufactured to the precision requirements of railway car girder applications — one of the more demanding duties in the structural-steel world, where sections carry dynamic loads, vibration and fatigue cycles for decades.
Profile No. 19 denotes the standard 190 mm section height in the established GOST profile series, a dimension widely specified across rolling-stock construction and general structural engineering.
Hot rolling produces a section with continuous grain structure and consistent mechanical properties along its length, the baseline requirement for load-bearing members. While engineered for railway car building, the same section serves general construction: floor beams, lintels, crane runways, platforms and machine frames.
At nine dollars per unit of supply with a 200-piece minimum, the product addresses steel traders, railcar builders and repair plants, construction companies and fabrication shops buying structural sections in commercial volumes from Russian mills.
