https://www.zhongheindustry.com/products/forged-erection-anchor.html
A forged erection anchor is a type of fastener used in construction to secure steel structures to concrete foundations. It consists of a forged steel anchor bolt with threads at one end and a hooked end at the other, which is embedded into the concrete. The hooked end is then used to attach the steel structure to the anchor bolt. Forged erection anchors are designed to withstand high loads and stresses, and are often used in the construction of buildings, bridges, and other large structures.
