All anchors react with oxygen in the atmosphere to form an oxide film on the surface. Unfortunately, the iron oxide that forms on ordinary carbon steel bolts continues to oxidize, causing the corrosion to continue to expand and eventually form holes. You can secure the surface of the bolt with an anti-oxidation paint or bolt plating (for example, zinc, nickel and chrome), but as we all know, this protection cannot be just a thin film. If the protective layer is damaged, the bolts below will start to corrode. Therefore, the four pieces anchor is difficult to resist corrosion.
How to correctly select the specifications and models of the four pieces anchor in the reinforcement project?
Different types of anchor bolts have different applicable substrates or scenarios and anchoring effects due to different mechanisms of action and structural forms.
It can be said that the quality and effect of the anchor bolt construction are largely due to the appropriateness of the anchor bolt selection.
In addition to considering the performance difference of anchor bolts, the selection of anchor bolts should also consider the properties of the base material, the compression properties of the anchorage connection of steel bars (tension, compression, center shear, and edge shear), the type of structure to be connected, and whether there is seismic fortification. elements such as regulations.
