There are primarily two types of resin anchors polyester and epoxy. Polyester resin anchors are typically used for medium loads and general applications, while epoxy resin anchors are designed for heavy-duty applications requiring enhanced strength and bond performance. The choice between these two types depends on various factors, including load requirements, environmental conditions, and the type of concrete. Additionally, some resin anchors are designed to be used with certain types of rebar or meshwork, providing further versatility for construction professionals.

The design of an M8 wedge anchor is simple yet effective. It consists of a threaded rod with a nut and washer, accompanied by a wedge-shaped expansion sleeve. When installed, the anchor is drilled into a pre-drilled hole in the concrete, and then the bolt is inserted and tightened. As the bolt is tightened, it pulls the wedge-shaped sleeve against the sides of the hole, creating friction and causing the sleeve to expand. This expansion locks the anchor securely in place, providing a strong hold that can withstand significant loads.
