115RE AREMA Standard SS Grade Railway Rail for Global Railroad

115RE AREMA Standard SS Grade Railway Rail for Global Railroad

115RE rail is one of the most widely used standard heavy rails compliant with AREMA 2019 standard, serving as the mainstream rail section for North American, Australian and Latin American railway systems. Converted to metric unit, 115RE rail equals approximately 56.9kg/m. It features stable sectional structure, high structural rigidity and outstanding fatigue resistance, perfectly designed for standard Class I railway lines, passenger-freight mixed traffic and medium-heavy haul railroad projects.

115RE steel rail adopts precisely controlled carbon steel and low-alloy steel smelting technology, providing excellent wear resistance and impact resistance under long-term cyclic load. We supply standard hot-rolled 115RE rails and multiple strength grades including SS, IS and HH head-hardened versions. Complete matching fastener sets and customized processing services are available to support turnkey railway construction projects.
