How to find a trustworthy self-drilling anchor manufacturer in China

With the development of the geotechnical anchoring industry, more and more constructors choose self-drilling hollow anchor bolts for engineering construction. Compared with traditional common anchor bolts, self-drilling hollow anchor bolts not only save cost but also are easy and fast to install. Compared with foreign manufacturers, Chinese manufacturers have the advantages of advanced technology, high quality, and lower price. However, there are many different products in the Chinese market, how should we find a trustworthy self-drilling rock anchors manufacturer in China?

1.What is a self-drilling hollow anchor?

Self-drilling hollow anchors are also known as anchor bolts, rock anchor bars, rock bolts, rock bars, and so on. They consist of a hollow anchor bar a drill bit, a nut, a plate, a coupler, and a centralizer. The hollow anchor bar is threaded throughout and hollow in the center, allowing the functions of the drill bar and grouting pipe to be combined into one. By combining drilling, grouting, and anchoring in one, self-drilling hollow anchors can directly penetrate the formation to complete grouting, while anchoring to strengthen the formation's weakness. Due to their excellent performance and strong anchoring ability, they are widely used in a variety of fields, including construction, municipal engineering, mine support, subway tunnels, and more.

2. What are the advantages of using self-drilling hollow anchors in engineering construction?

The use of self-drilling hollow anchors in engineering construction has several advantages, including:

(1) Good reinforcement effect:

The self-drilling hollow anchor can be anchored in the stratum. Through its self-weight and drilling force, it can quickly penetrate the fixed soil layer and fix the structure in the hole. This greatly improves the reinforcement strength and effect, making the structure feel more solid and stable. During grouting, the grout is injected upward from the bottom of the hole, ensuring full and good compactness, resulting in high-quality grouting.


(2) Fast construction:

The self-drilling hollow anchor bolt integrates drilling, grouting, and anchoring. With this method, one drilling can complete the grouting and anchoring process. Compared with conventional anchor construction, this method reduces the procedures of drilling, installing anchor rods, and inserting grouting pipes, thus greatly improving construction efficiency.


(3) Easy to use:

The self-drilling anchor consists of a hollow anchor bar, drill bit, coupler, nut, plate, and centralizer, which makes it relatively simple in structure and easy to construct when connecting with a drilling rig and grouting machine. Typically, only 2-3 people are needed to ensure the project can be carried out normally, which greatly reduces labor costs.


(4) High applicability:

The self-drilling anchor bolts have high applicability and can be used in various geological conditions. They can be connected with different drill bits for drilling construction, providing effective support and reinforcement. After drilling is completed, the rods remain in the hole without having to exit, thus avoiding the risk of collapsing the hole and saving time for penetrating other rods, reducing the difficulty of construction at the same time.

3. What should customers pay attention to when selecting a self-drilling anchor manufacturer?

When choosing a trustworthy self-drilling anchors manufacturer, there are the following factors to consider:

(1) Qualification and reputation:

It is essential to select a manufacturer with professional qualifications and a high-quality customer reputation. A truly professional manufacturer must possess extensive skills and experience and be certified by a reputable certification body to ensure they can provide high-quality self-drilling anchors to their customers.

(2) Product quality:

Product quality is key. Good product quality can provide a strong guarantee for the stability and durability of the project. Therefore, when choosing a self-drilling hollow anchor manufacturer, it is important to select one with high-quality materials, machinery, and equipment to ensure that they produce products of superior quality and long service life.


(3) Technical support:

The self-drilling anchor bolts required by different customers vary. Having professional technical support can solve various problems encountered by customers and provide them with professional solutions, even if problems arise. Therefore, it is very important to choose a self-drilling anchor manufacturer with professional technical support capabilities.


(4) Production strength:

Having a modern production line and stable production capacity is a consideration when choosing a self-drilling anchor manufacturer. The production strength should be strong enough to ensure that each order is shipped on time and in the correct quantity, and have the ability to provide customers with quick response, real-time technical support, and after-sales guarantees.
