China Nut is mainly used in steel structure engineering. It is used to connect the connection points of steel structure steel plates. Iron will rust, but steel structure bolts are not easy to rust. However, it is difficult to avoid rust in some special environments. This problem, for example, after being corroded by natural weather in a long-term humid environment at the seaside, it may cause rust problems. If this problem can be solved, it is only necessary to replace it. If steel structural bolts are exposed to rain or some kind of liquid, they will cause rust. Corrosion such as bird droppings in places with abundant seawater in the wild is the cause of rusting of steel structural bolts. In order to solve this problem, we must take corresponding actions and take moisture-proof measures for the steel structure bolts.

　　There is still a way to prevent moisture. Solvent-free paint can be used. Here, dipping paint without oxidizing components, such as epoxy urethane or undenatured epoxy-based dipping paint.

The use of these paints by Bolt Factory can effectively protect the anchor bolts of the steel structure. It has a good isolation and reuse for isolating water vapor in the air. The main steel structure bolts do not oxidize and rust, and the hardness performance of the steel can be guaranteed. No loss, so as to ensure the fastness of the anchor bolts and the safety of the corresponding equipment.
