High Strength Polyester Mine Grid For Mine Application

Product Detail

Description 

 

High Strength polyester mine grid for mine application is made from High Tenacity Polyester Yarn coated with a Flame Resistant, anti-static coating. It is manufactured in a range of tensile strengths from 300kN/m to 1000kN/m, standard roll size is 5m*100m, but customized roll size is available. The wide range of the mining grid product line allows mines and quarries to customize to fit their need. With the easily application, Mine grid is widely used in underground and tunnel engineering. Such as long walls and high walls and other fire proof structures.
