Firstly, the material choice plays a significant role. Steel, being the most common material, is available in different grades like carbon steel, stainless steel, and alloy steel. The grade determines the rod's durability, resistance to corrosion, and overall performance, which can significantly impact the price. For instance, a higher-grade stainless steel rod will generally cost more than a standard carbon steel one due to its superior properties.

Chemical anchors consist of a resin or adhesive that, when mixed with a hardening agent, polymerizes to form a strong bond with the base material. These anchors are typically used in conjunction with metal rods or bolts that are inserted into drilled holes. The chemical reaction that occurs once the resin is mixed makes the bond resistant to shear and tensile stress, significantly outperforming traditional anchoring solutions in many scenarios.
