1. Principles: Metal anchors achieve a tight connection to the base by pre-embedding the anchor into concrete or other substrates, while mechanical anchors achieve their anchoring effect through negative and positive friction.
2. Bearing Capacity: Because metal anchors are deeply embedded in the base, they can withstand significant tensile and shear forces, resulting in greater bearing capacity and anchoring strength than mechanical anchors.
3. Applications: Because metal anchors require pre-embedding, their use requires specific requirements. Mechanical anchors can be used in general construction and structural engineering and are widely used.
