Anyang Railway Equipment Co., Ltd is a professional manufacturer of Composite Sleepers, compared with wooden sleeper and steel sleeper, which are ideal for ballasted railway tracks, which has better damping and less wear.
Railway sleepers, also called railroad ties, railway crossties, or railway ties, are important railway components of the rail industry. Generally, the rail sleeper is always laying between two rail tracks to keep the correct space of the gauge.
Anyang Railway Equipment Co., Ltd is a professional manufacturer of Composite Sleepers, compared with wooden sleeper and steel sleeper, which are ideal for ballasted railway tracks, which has better damping and less wear.
Composite sleeper, also known as a synthetic sleeper, is composed of continuous glass fiber reinforced polyurethane foam material, it has higher strength and is widely used as a structural material, besides, it is light in weight, insulating and resistant to aging, heat-insulating, chemical-resistant.
The shape of the composite sleeper is similar to that of an ordinary wooden sleeper. The construction and installation process of composite sleepers is simple, and the composite railway sleepers can be sawed, planed, nailed, screwed, and glued with ordinary woodworking tools. The composite railway sleepers have a low thermal expansion coefficient and thermal conductivity, high anti-seismic, compressive, tensile, and flexural strength.
Composite sleepers can maintain good electrical insulation and stability even in long-term adverse weather conditions. The composite railway sleeper has better processing performance than the concrete sleeper. It is light in weight and can be processed into any length. It is not necessary to customize the mold for each length. After repairing the nail hole on the composite sleeper. It can be used again with long service life.
China published the performance standard for Synthetic sleepers of fiber-reinforced polyurethane foam (CJ/T 399 - 2012). The productivity of synthetic sleepers in Anyang Railway Equipment Co., Ltd(AT) is 10,000 Pcs/month. The synthetic sleepers produced by Anyang Railway Equipment Co., Ltd(AT) have been used widely on all types of rail transport systems, particularly on switches, turnouts, bridges/viaducts, and other projects in high-speed and metro railway construction.
