Introduction
High strength flame retardant polyester grid for mining is made by weaving and coating with high-strength polyester industrial filament as main material.
Features:
Compared with metal mesh, it has the characteristics of light weight, high strength, flame retardant, antistatic, corrosion resistance, etc. It is easy to install and use.
Application:
It is widely used in false roof support, roadway support and permanent roadway support reinforcement in coal mines and metal mines.
