Anchors serve to link structural components, typically metal parts like brackets and plates, to foundational materials like concrete and brick. There are two main types of anchors: mechanical and chemical. The choice between them hinges on various factors, including the strength and depth of the foundation material. External considerations such as temperature and corrosion will need to be considered also when deciding which type to use.
In chemical anchors a resin is used to fill in the extra space and secure the anchor in the hole, whereas mechanical anchors typical use expansion or screw in force to secure components down.
