First of all, the U-shaped bolts should be handled with care, so as to prevent impact, damage to the package and damage to the bolts. Before using upstairs, try not to open the box as much as possible to prevent damage to the sealing of the package. If you unpack some of the bolts, you should also keep it intact. It is well packed to prevent dust and rust from being stained. In the process of transportation, storage and use, you should install and unload with care to prevent damage to the threads. If you find that the threads are severely damaged or the bolts that have been exposed to rain should not be used again.
Secondly, U-shaped bolts should be stored in moisture-proof, rain-proof, and dust-proof, and should be stored according to types and specifications, so that they can be easily found during use. The high-strength bolted auxiliary packaging box should be placed on the bottom layer, the bottom layer should be overhead, and the height above the ground should be about 300 mm, and the yard height should not exceed three layers. If high-strength bolts are stored on the construction site, they should be stored in a dry, ventilated, rain-proof and moisture-proof warehouse, and they should not be damaged or contaminated with stolen goods.
