Rail sections, as critical components of railway tracks, are subject to stringent and well-defined specifications and profiles. The specifications of rail profiles are primarily defined by their cross-sectional shape, dimensions, and weight per meter. The most common cross-sectional shape for track rails is the I-beam design. This configuration effectively reduces weight while maintaining strength, leading to cost savings.
The designation of rail types is primarily based on their weight per meter. Common examples include 50 kg/m, 60 kg/m, and 75 kg/m profiles. These different rail steel sections are suited for various railway applications. GNEE RAIL supplies multiple types of running rails, including light rails (9kg/m, 22kg/m, 30kg/m, etc.), crane rails(QU70 QU80 QU100 QU120), and heavy rails.
The 60 kg/m rail profile is a widely utilized specification in mainline railways. Its approximate dimensions are: height ~176 mm, base width ~150 mm, and head width ~73 mm.
GNEE RAIL manufactures 60kg rail sections using steel grades such as U71Mn/U75V, which provide high strength and wear resistance. This enables the track rails to withstand greater train loads and frequent cyclic wheel contact forces. Furthermore, rail steels processed through heat treatment and other metallurgical processes exhibit a longer service life. This significantly prolongs rail replacement intervals, reduces track maintenance frequency, and lowers operational costs.
