Cold galvanizing - The best solution for anti - corrosion in the industry

The dangerous impacts of corrosion on metals have been known for years. For almost as long as metals have been a construction material, people have constantly found a solution to improve its life span in corrosive environments. One of the most widely used techniques for protecting metals in the industry is cold galvanizing.

What is cold galvanizing? The definition and the compounds of cold galvanizing

1. The definition of cold galvanizing - why is it needed in the industry?

Cold galvanizing is basically painting a piece of steel with zinc-rich paint. There are no tanks or planning fundamentals other than the gear you would need to paint any other material (blasting tools, spray guns or rollers, etc.). Since the coating is just zinc-rich paint, it will not have the durability of hot-dip galvanizing in terms of scraped spot resistance, cathodic security, and service life (or time to begin with support). The cathodic security advertised by zinc-rich paint is less than hot-dip galvanizing because there are covers and other components within the paint which constrain the network of the zinc particles.

When the zinc coating is applied to the barrier, it dries and solidifies to create a protective zinc oxide layer that is impenetrable to air and moisture, thus eliminating one of the components required for corrosion to occur – the electrolyte. Because the underlying steel substrate is incapable of coming into contact with external air or moisture, further corrosion is prevented.

2. What are the cold galvanizing compounds that protect from corrosion?

Cold galvanizing compounds became the radical component of corrosion restraint for most projects and were specified by product engineers in manufacturing processes as an in-plant method of galvanizing.

Enter cold galvanizing compounds to help prevent corrosion for iron and steel. A cold galvanizing compound is a high-end solution that is ideal for touch-ups or full-scale project applications. A cold galvanizing compound has the characteristics of a paint, but it is not a paint.

Some uses for the protections that cold galvanizing compounds provide include: bridge, construction, industrial maintenance, manufacturing, power plants, water & waste plants, transmission tower, offshore marine rigs.

3. The benefit of cold galvanizing in metal construction and others

Cold galvanizing is the ideal solution when compared to other metal coating lines. They possess many outstanding advantages to meet a variety of needs in many different fields.

• In order to meet the needs of users, cold galvanizing has a very diverse color palette. It is suitable for many projects and uses.

• Many products are easy to apply, do not need to be blended and do not require experienced people to apply.

• Cold galvanizing features a quick drying time and the painting process is independent of climate conditions.

• Effective resistance to corrosion, abrasion, and extraordinary climate conditions. Some products also have anti-friction, resistance to force and anti-peeling properties. Thereby protecting and prolonging the life of the works.

• The product can also cover the defects on the surface of the material, creating a shiny, durable and highly aesthetic coating for the works.

Wrong assumptions about cold galvanizing that people need to know

There is a lot of mis-leading information about cold galvanizing and its compounds. Many people think a cold galvanizing product is just simply an ordinary paint that can be applied in barriers. But since cold galvanizing products are not the paints they are so often mistaken for, they have to be applied properly to work as intended.

Does it need to be cold?

The answer is No. The phrasing cold galvanizing does not mean that it is required to be applied in a cold condition. 

Is it used for small areas? 

Cold galvanizing compounds can be used for the overall galvanization of structures and not just for touch-ups.

Does cold galvanizing have good quality? 

Not with the right products. Numerous individuals have had destitute involvement with inferior quality. Currently, there are many models released with different compositions and properties, appropriate for each case and particular prerequisites for the paint layer. People need to look for cold galvanizing product’s information to choose the appropriate one.

With many unique advantages, cold galvanizing is the quality arrangement for corrosion protection, providing significant measurable benefits to many construction. It is cost-effective and labor-saving, comprehensive and effective protection as well as highly aesthetic. The zinc coating market is also increasingly diverse and constantly improved, in order to meet the requirement of users.
