DESCRIPTION：
Bottom of Form
Friction Bolt Stabilizers are a popular choice for hard rock mining, offering superior performance and ease of handling. Made of 55Q material and available in various sizes, these stabilizers feature a metal strip shaft folded into a slotted tube, providing axial and radial expansion forces. With extensive testing and high-quality welding, they are easy to install and suitable for underground metal ore mining. Additionally, black or hot dip galvanization is available, making them a versatile and reliable option for mining applications. Prices are available upon request based on your specific drawings.
