Throughout the entire lifecycle of mechanical anchor bolts, the usage, maintenance, and repair phases account for the vast majority of their total lifespan, and these are the stages where mechanical anchor bolts truly demonstrate and fulfill their value.

Construction projects are characterized by large scale, heavy tasks, high investments, tight schedules, and strong seasonal fluctuations. For mechanical anchor bolts that are subjected to constant field work and harsh conditions, mandatory maintenance is especially crucial. Analysis of common major failures in mechanical anchor bolts shows that 56% of major failures are caused by a lack of maintenance and保养, 38% are due to errors in regular maintenance, and 6% are due to mistakes.

Likewise, from the entire lifecycle of mechanical anchor bolts, the usage, maintenance, and repair stages account for the vast majority of the lifespan. These stages are crucial for the true functioning and value demonstration of the mechanical anchor bolts. As a result, it is imperative to strongly promote mandatory maintenance for mechanical anchor bolts.
