Which anchors are recommended for fastening hangers to a concrete building?

Lead anchors or expansion shields are recommended for fastening hangers to a concrete building because they provide a secure and load-bearing connection in concrete structures. These anchors work by expanding against the sides of the drilled hole when a bolt or screw is inserted, creating a strong grip that can withstand significant tension and shear forces.

In the context of concrete applications, using lead anchors or expansion shields ensures that the connection can accommodate the inherent rigidity and compressive strength of concrete while preventing any movement that could occur with less secure fastening methods. They also allow for easier installation and adjustments since they can be set in pre-drilled holes, making them ideal for various construction and maintenance applications.

This method of fastening is crucial for maintaining the integrity of the structures and ensuring that any hung components, such as pipes or electrical conduits, are reliably supported in a manner that conforms to building codes and safety standards.
