Cable trench cover plate is a product with beautiful appearance and easy installation, commonly used in factories, workshops, mines and other places. The steel with a square grid in the middle of the product has a relatively long service life. So, what issues do we need to pay attention to in order to extend the service life of the product?

1. Load. Due to changes in load, the temporary use has altered the specifications of the composite cable trench cover, resulting in insufficient structural load-bearing capacity. The cover plate is deformed, deformed, and expanded due to various accidents. This leads to the weakening of the cross-section of the parts, warping of the rods, and breakage of the connections.

2. Installation. During the installation process of the groove cover plate, other reasons are all caused by manual manufacturing, resulting in improper welding and installation, and other reasons leading to damage to the galvanized groove cover plate.

3. Galvanized. The damage to the trench cover plate after hot-dip galvanizing is caused by cracking and warping of parts or joints due to temperature differences during operation. Due to chemical corrosion and severe electrochemical corrosion, the cross-section of the groove cover plate parts becomes weaker. Suggest hot-dip galvanizing surface treatment.

4. Apply anti rust paint. When using composite cable trench cover plates, they should be kept clean and not covered by various dirt, especially corrosive residues. When fixing the steel grating with bolts, it is necessary to regularly check whether the bolts are loose and promptly deal with hidden dangers. If the galvanized layer is found to be missing, anti rust paint should be applied in a timely manner.
