For the maintenance of galvanized coil is a very simple but also very important work, if you do this work, you can easily extend the service life of the product, compared with the failure to repair or replace the practice, the maintenance method is done, is conducive to the operation of the machine. Now, let's take a look at the specific method. 

Under normal working conditions, the thickness of galvanized layer of hot dip galvanized coil is up to 50um and can be safely used for 30 years. This is the use of the anode protection principle of iron matrix, hot dip galvanized sheet this practice makes pure zinc layer in the atmospheric environment to generate a dense protective film, to prevent zinc corrosion. But if we encounter a wet environment, we will be through the asphalt coating or sealing groove to isolate the direct contact between the medium and the zinc layer, to prevent the corrosion of zinc layer perforation.

 From the above, we can know that the quality of the product is the standard for our evaluation of the company, but understand these maintenance methods, can help to play the function of galvanized coil products, in the extension of life at the same time, to ensure the safe use of galvanized coil in the number of years. To make sure our products last longer.
