Characteristics of sleeper

Good elasticity, light weight, simple manufacture and good insulation performance. The connection between the fastener and the wooden sleeper is simple, the laying, maintenance and transportation are convenient, and the friction coefficient between the wooden sleeper and the gravel ballast is large.
