Pre buried channel is a pre install in concealed engineering in parts, to a steady role in external engineering, mostly made of metal in the structure first left plate and the anchor bolt, it can be used to connect components. It can be used as the order of fixed connection, generally require the use of embedded parts need to carry out relevant processing according to the drawings, and then measuring the positioning and design support and so on.

The use of pre embedded channel is so extensive, but if used for a long time, corrosion and rust will occur, then it is necessary to do a good job of anti-corrosion. First of all, the need for surface treatment, ensure that no dust and debris on the surface, then the storage environment is to place a dry place, do not put in a humid environment inside, and then avoid some strong acid substances, which can prevent the surface reaction, causing damage to the protective layer on the surface of lead the embedded parts of corruption, so it is very necessary for daily protection, can effectively prolong the service life of pre buried channel.
