Product description
Underground construction double corrosion protection anchor bar based on the advanced molding technology, has the characteristics of high-strength, lightweight. Under the prerequisite of ensuring the bolt ultimate tensile strength, reasonable grouting aperture increases, solve the blocking problem. Makes grouting more smoother, fuller and more dense. While reducing the engineering cost and builders working strength, have achieved good results in every aspects.
