Metalizing Gun
About Our Product Industrial Metalizing Guns For Metal Coating
A Metalizing Gun sprays molten zinc or aluminium onto a steel surface to build a protective metal coating that stops rust before it starts. It's the equipment behind long-term corrosion protection on bridges, structural steel, and industrial equipment that has to survive years of exposure to weather, moisture, or marine air.
Vands Engineering Solutions manufactures and supplies these thermal spray equipment for corrosion protection work across India. As one of the established Metalizing Gun Manufacturers in India, we build ours to keep the wire feed and spray pattern steady, because an uneven coating is really just a corrosion problem waiting to show up later.
What Is a Metalizing Gun?
It is a thermal spray system that melts a metal wire, most commonly zinc or aluminium, and sprays the molten metal onto a prepared steel surface using compressed air. As the droplets hit the surface, they cool almost instantly and bond mechanically to it, building up a coating that acts as a barrier and, in the case of zinc, also gives sacrificial protection against rust.
There are two common types: flame metalizing guns, which melt the wire using an oxy-fuel flame, and electric arc metalizing guns, which melt it using an electric arc between two wire feeds. Both are used for the same purpose, but arc guns tend to be faster and more efficient for high-volume corrosion protection jobs, while flame guns remain popular for their simplicity and lower equipment cost.
Vands Engineering Solutions Top Benefits of Using a Metalizing Gun
Long-Lasting Corrosion Protection
1. Zinc and aluminium coatings can protect steel for decades with barely any upkeep
2. Zinc corrodes first, giving the steel underneath sacrificial protection
3. Cuts down how often structures need repainting or major maintenance

No Damage to the Base Structure
1. Applies the coating without heating the steel enough to warp it or change its properties
2. Safe for structural steel where strength really can't be compromised
3. Doesn't need the surface to be dismantled or heavily reworked first

Frequently Asked Questions
It’s used to spray molten zinc or aluminium onto steel surfaces to build a protective coating against rust and corrosion. This process, called metalizing or thermal spraying, is widely used on bridges, structural steel, and equipment exposed to weather or marine conditions, where long-term protection matters more than a quick paint job.
A well-applied zinc or aluminium coating can protect steel for several decades with little to no maintenance, depending on the environment and coating thickness. This is one of the main reasons the process gets specified on infrastructure projects, where repainting or major repair work later would be expensive and disruptive.
A flame-type gun melts wire using an oxy-fuel flame, while an arc-type gun uses an electric arc between two wire feeds. Arc guns are generally faster and more efficient for large jobs, while flame guns are simpler to set up and cost less, making them suitable for smaller or occasional work.
Yes, the surface usually needs to be blasted clean, often with steel grit or abrasive, to remove rust, mill scale, and contamination and create a rough profile the coating can bond to properly. Skipping proper surface preparation is one of the most common reasons a coating like this fails prematurely.
Zinc offers sacrificial protection, meaning it corrodes before the steel underneath does, which makes it a strong choice for general corrosion protection. Aluminium tends to perform better in high-temperature or highly saline environments like marine and offshore settings. The right choice depends on the specific exposure conditions involved.
Price depends heavily on the type — flame guns are generally cheaper and simpler, while electric arc guns cost more upfront but work faster on large jobs. Total cost also depends on wire size, feed system, and included accessories, so it’s best to share your project details with a supplier for an accurate quote rather than going by a fixed number online.
