Regarding the maintenance of the flowerless galvanized sheet, it is a very simple but also very critical work. IBC Tianjin Industries Co.,Ltd is a manufacturer & supplier of high-quality galvanized steel products. Such as Galvanized Coils, Galvanized Steel Sheet, Galvanized Steel Pipe, and other steel products. We sell various types and standards of galvanized steel products all over the world at low prices and good quality.
If this work does well, the life of the product can be easily increased. It compare with common failures to repair or the replacement method. And the maintenance method do, which is beneficial to the operation of the equipment. Below, let’s take a look at the specific methods.
Firstly, Flowerless Galvanized
In all normal office environments, the thickness of the hot-dip galvanized sheet is over 50um, which can be used safely for 30 years. This is also the basic principle of using iron substrate anode protection.
This kind of hot-dip galvanized sheet makes the pure zinc layer into a high-density protective film in ambient air to avoid zinc corrosion.
But if you encounter a wet and cold natural environment. You need to block the direct contact between the substance and the zinc layer. According to bitumen coating or sealing, so as to prevent the hot-dip galvanized layer from eroding holes.
Secondly, Maintenance of Flowerless Galvanized Sheet
From the above, we can understand that the quality of the product is the norm for everyone to appraise the enterprise. But understand that this maintenance method can help the full function of product.
At the same time as the continuous service life. To ensure the safe application of the flowerless galvanized sheet within the time limit. Only then can we ensure the longer-term application of your products.
Because of the different treatment methods in the coating process, the surface condition of it is different. Such as general spangles, fine spangles, flattened spangles, zinc-free spangles, and their pickled and phosphate surfaces.
The flowerless galvanized sheet should have an excellent appearance. And there must be no defects that are harmful to the application of the product. Such as no plating, holes, cracks and sludge, excessive plating thickness, scratches, chromic acid stains, white rust, etc.
International standards are not very clear on the actual appearance defect requirements. Some actual defects should be indicated on the contract when ordering.
Above two methods are list the characteristics of the flowerless galvanized sheet. The following information offers some guidance on the general care and maintenance of hot dip galvanized steel products.
Firstly, to avoid long periods of exposure of your galvanized steel product to environments where the pH is below 6 and above 12.
Outside the range of pH 6-12 the galvanized coating can suffer greater corrosion than normal.
Secondly, to avoid direct contact of your galvanized steel product with dissimilar metals. Such as brass and copper, particularly in corrosive environments.
Where dissimilar metals are to be used together ensure that there is an insulator between the dissimilar metal and the galvanized product.
Thirdly, do not constantly abrade clean your flowerless galvanized sheet product. And where possible, avoid abrasive washing of your galvanized product altogether.
One of the ways in which galvanizing protects steel from corrosion is by the development of a thin barrier film of insoluble zinc corrosion products (known as a patina) on the outer surface of the galvanized steel through exposure to the atmosphere. Abrasive cleaning will wash away this protective patina. And the galvanized article will have to build up this barrier protection again, consuming more of the zinc. Constant abrasive cleaning will consume the zinc more quickly and therefore may reduce the life of your galvanized steel product.
Fourthly, galvanizing may be cleaned using a water-based emulsifier, alkaline-based cleaners with a pH of 12 or lower or organic solvents.
Then rinse the area with fresh water and simply wipe clean with a soft cloth. Please consult the your galvanizer or the IBC Tianjin Industries Co.,Ltd. If you have any concerns in regards to cleaning your product. For galvanizing product situated in a highly corrosive environment.
Eg. coastal, heavy industrial, etc. It is recommended the product be rinsed with potable water on a regular basis. Particularly under sheltered conditions (i.e. not exposed to rain and sun).
Avoid long term storage of any flowerless galvanized sheet product in damp and poorly ventilated conditions. Ensure the storage location is dry and there is effective ventilation.
If there is physical damage to the galvanized coating of the product (e.g. coating is chipped or fabrication after galvanizing has taken place). It is recommended that the damaged area be repaired in accordance with AS/NZS 4680. See Repairing Hot Dip Galvanizing or talk to IBC Steel Group.
