Rails' weight less than or equal to 30kg per meter are called light rails. Light rails are used as tracks with lower loads, such as the laying of temporary transportation lines and light locomotive lines in forest areas, mining areas, factories, and construction sites. Or light crane track.
25 lb rail (ASCE25) is a kind of American standard light rail. It is mostly used in the construction of mine rails. It is similar to the 12kg rail in China. We have a large amount of inventory that can be sold together. We have long-term export to frame construction companies in South America and other regions. At the same time, we supply and rail Provide a one-stop procurement service for all kinds of accessories.
