    Crane rails, that is, crane rails, have a lower height, larger head width and waist thickness, and only require testing of chemical composition and tensile strength. Used for laying crane and trolley tracks. Rail material:U71MN Rail specifications: QU70kg/m, QU80kg/m, QU100kg/m, QU120kg/m Length:

    Heavy rail is the production of nominal weight greater than or equal to 30kg / m rail steel, requiring higher toughness, wear resistance, resistance to crushing and resistance to brittle fracture. Production process quality requirements are strict, in addition to ensuring its

    Light rail is less than or equal to the nominal weight per meter 30ka rail. The quality requirements of light rail are lower than heavy rail, only its chemical composition, tensile strength, hardness and drop test are required to be examined. Light
