Post tension arc flat anchor is a type of anchor that is used in post-tensioning systems. It is designed to provide a secure and reliable connection between the post-tensioning cable and the concrete structure. The anchor is made up of several components, including a flat plate, a wedge, and a bearing plate.

Post Tension Prestressed Flat Slab Anchorage refers to a type of anchorage system used in the construction of flat slab structures. It consists of a set of prestressing cables that are anchored to the concrete slab using specialized anchorages. These anchorages are designed to withstand the high tension forces generated by the prestressing cables, which are used to counterbalance the weight of the structure and strengthen it against external loads.

Mining and Tunneling Expansion Shell Anchor geometry showing the internal and external forces Eq. (1) indicates that the friction angle for the interface between the cone and the inner leaf surface must be less than the friction angle for the interface between the outer shell and the rock by an amount greater than the taper angle of the cone and inner leaf interface. In many cases, this condition is unlikely to be achieved because anchors are manufactured from cast components with an inherent roughness; the friction angle associated with this less than smooth surface is then often increased following zinc coating.

M16 Expansion Shell 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. Here are some common rock bolt applications and types you should know.
These rock bolts consist of a steel tube and an expansion shell that is inserted into a drilled hole in the rock. A cone-shaped wedging expansion shell is connected to the tube and expanded by using a mechanical tool or hydraulic pressure. This creates a compressive force that anchors the bolt into the rock, providing additional support and stability.
