performance

　　It is made of polymer with strict ratio and then stretched vertically and horizontally. It has high tensile modulus and strength, enduring resistance to mechanical damage, and can withstand stress in various harsh environments.

scope of application

　　Roads, railways, airport runways, docks, bridges, abutments, embankment protection, etc.
