Premium 136RE HH Grade Railway Rail

Premium 136RE HH Grade Railway Rail

136RE rail (136lb/yd) is the heavy-duty flagship rail of AREMA standard, widely known as the optimal solution for Class I heavy haul railway lines. The metric weight is approximately 67.3kg/m. With larger sectional area, higher rigidity and stronger load-bearing capacity, 136RE rail is specially engineered for high axle load, high traffic volume and long-distance heavy freight railway transportation.

136RE heavy rail adopts high-purity carbon steel and low-alloy steel formula, with strictly controlled carbon and manganese elements to achieve ultra-high hardness and fatigue resistance. It is the primary rail type for North American heavy haul mainlines, Australian mineral railways and large-scale international freight railway projects. We provide full-grade products including standard SS, intermediate IS and head-hardened HH versions, with complete supporting accessories and one-stop engineering supply service.
