Things to consider after Galvanizing
You should note that sometimes, issues may arise after the galvanizing process is done successfully. Many professionals are working and providing services for galvanizing of iron and steel. However, it is important to note these issues which affect the resting or corrosion-resistance property of the galvanizing. Galvanizing is used to increase the life of steel and iron with the help of zinc coating. Useful life of steel and iron is increased with the help of galvanizing. There are many things which must be considered when you are using galvanized metals. There are major companies which hire these professionals to make sure that the process of galvanizing can be completed with perfection. Cost of galvanizing is also small as compared with other forms of coating. Useful life of metals can be increased with the help of galvanizing. Therefore it is a good choice of using galvanized metals in construction processes. Demand of galvanizing is also increasing with time because it is giving long term benefits without adding costs.
1. Dross Pimples
How does it happen?
Dross trapped in the galvanized coating may give the coating a gritty or rough look. It is important to note that this does not affect the quality of galvanizing
It is the product of iron particles in the bath that react in the zinc and stick to the surface in the galvanizing process.
How to prevent it?
- Properly wash the metal surface. To help prevent pimples, it’s important to remove excess oil, dirt, and sweat daily. …
- Know your metal type. Any metal can get pimples, no matter their surface type
It effects
Acidic foods must not come in contact with galvanized metals. Corrosion can take place when acidic foods come in contact with galvanized metals. As a result the food will not be safe for eating and the metal will also suffer from corrosion and its useful life will be reduced. When you are using acidic foods then make sure that you are not using them in galvanized metals.
2. Welding Seepage / Weld Metal Porosity
How does it happen?
- The presence of moisture can lead to problems.
- Plating compounds with zinc, such as in the galvanization process, can create a problem.
- Improper use of antispatter compounds, sprays, or gelscan be a major contributor to porosity.
How to prevent it?
- The presence of moisture on the zinc should be avoided.
- Do not Plat compounds with zinc, such as in the galvanization process
- Proper use of antispatter compounds, sprays, or gels cannot be a major contributor to porosity.
Effects
Soft water can lead to corrosion of galvanized metals. Make sure to avoid direct contact of soft water with galvanized metals so that the problems of corrosion can be avoided. High levels of oxygen and carbon dioxide in soft water can lead to corrosion in galvanized metals which will reduce the useful life.
3. Uneven Discolouration
How does it happen?
The leading cause of stainless steel discoloration is using violently abrasive chemicals like salt, chlorides, and bleach that will destroy its protective oxide layer.
How to prevent it?
- Adding Vinegar removes spots and some discolorationon steel and aluminum.
- Adding Club soda can removedeeper discoloration on steel.
- You Polishing the metal with olive oil once the patina is gone to makethe steel
- Adding Cream of tartar and boiling water removes the discoloredpatina on aluminum pots.
Effect
It discolour the metal
