Product Introduction
my country's heavy rail mainly follows the national standard GB and the railway industry standard TB. The current standards GB/T 2585-2021, GB/T 8365-2001, and TB/T 2344-2012 have heavy rail specifications of 43/50/60/75kg/m, of which 60kg/m is the mainstream and is also the mandatory standard for high-speed rail specifications. 75kg/m is mainly used for heavy-duty lines with large annual transportation volumes, such as the Daqin Line. Although 50KG/M is no longer used as a new station line rail, the stock is still large, and its use of U71Mn material is more cost-effective.

Product Packaging & Delivery
In order to prevent the heavy rail tracks from rusting during transportation, we will apply anti-rust oil on the surface of the rails. In order to reduce the wear of the rails, we will use steel belts or wooden boxes to fix them, so that customers can receive satisfactory products.
