38kg heavy rails refer to rails with a mass of 38kg per meter. They are mainly used for laying railways and are required to withstand the pressure, impact load and friction during train operation. They require sufficient strength and toughness. They can also be used for carrying slightly larger mine tunnels and factory workshops, transportation, crane hoisting equipment, and laying railway dedicated lines.
Rails are divided into light rails and heavy rails according to their weight, among which 38kg rails are a type of heavy rails. This type of rail is usually used in railway construction, especially for railway lines with large transportation volume and high speed.
The weight of a rail usually refers to the mass of each meter of rail. The heavier the rail, the stronger the carrying capacity, which is suitable for the operation of heavy-load trains or high-speed trains. 38kg heavy rails are generally used for medium-load railway lines and can withstand certain pressure and impact.
