The stability of a structure entirely depends on how strong the foundation is. This explains why many are considering micropiles for ground improvement and rock stability. Though they are smaller in size, micropiles are efficient in handling heavy architectural structures. The best thing about micropiles is that they not only work in congested and low

Rock bolts are crucial elements in stabilizing rock formations in various industries, from mining to civil engineering. They are used to reinforce and support rock structures to prevent them from collapsing or shifting, which can pose a serious threat to workers and structures. There are several types of rock bolts, each designed for specific applications.

Experienced buyers may find there is a difference in the model types of self-drilling anchor among all suppliers. Naming methods Atlas MAI (now belongs to Orica) self-drilling anchors are identified by the combination of alphabets & numbers. For instance, R32N R means the rope thread. 32 is the outer diameter of hollow bar. N represents

Hollow bar anchor manufacturers carry out tensile test to ensure the self-drilling anchor rods are strong enough. The values are plotted on a coordinate graph – with strain elongation along the x-axis and stress, typically in MPa, along the y-axis. Figure 1 shows a typical tensile stress/strain curve. Figure 2. Tensile capacity from self-drilling anchor

As a manufacturer of self-drilling anchor bars, Onton always pays attention to products from European famous factories. Recently I found one of their hollow bar anchors are a bit different in the terminal chamfer. I won’t evaluate how their process mode is, but will tell why we make the chamfer like this. The normal length of self-drilling

Introduction: The core of the Onton Self-Drilling Anchor Bolt is a hollow, thick-walled, central drilling rod with a drill bit at the top. The system is modular, meaning that the most appropriate configuration can be put together to suit on-site circumstances and the forces that apply. The self-drilling anchor bolts are available in the steel grade S460NH

Introduction Micropiles, sometime are called as minipiles, anchor piles or root piles, are widely used in foundations constructions. Especially for underpinning or emergency repairs, it is an effective method to provide reinforcement. Micropiles normally consist of high-strength, small-diameter threaded steel bar. After the injection of cement, micropiles can supply 1,000 tons strength and more. In
