As an alternative to rebar, FRP bolts have natural advantages in support. However, the quality of FRP bolts products on the market is uneven. Many companies choose unqualified raw materials to produce a large number of unqualified FRP bolts in order to seek their benefits. These products have flowed into major coal mines, posing a huge safety hazard.

According to relevant statistics, there are about 40,000 types of FRP products developed in various countries around the world. But because many companies do not have production qualifications, the FRP bolts that they produced do not meet the relevant national standards. So how to choose a qualified FRP bolt manufacturer? Zongxiang Steel Group will answer your questions one by one.

In fact, the quality of FRP bolt products can be judged from the following two aspects:

(1) From the surface of the product, qualified FRP bolts have uniform texture, no bubbles and cracks;

(2) From the perspective of coherent testing standards, the size, tensile strength, shear strength, torque, anchoring capacity, bearing capacity and antistatic performance of qualified FRP bolts should meet national standards.

Although the quality of FRP bolts currently produced in China have been improved greatly compared with the previous ones, it can meet the support needs of most mine roadways, but we cannot ignore the pursuit of high-quality FRP bolts.
