Paint for Galvanised Steel

GALVACOAT® is a tough, single application polyurethane top coat specifically formulated to adhere to non-ferrous metals such as zinc.

Most standard paints are designed for use on ferrous metals. Zinc is a non-ferrous metal and therefore it requires special etch primers. Galvacoat® was specially designed for non-ferrous metals thereby eliminating the need for these etch primers. If the wrong paint system is applied it can react with the galvanizing to form a layer of salts which causes the paint to lose adhesion over a period of time.

 

Galvacoat® adheres to the galvanizing and does not allow salts to form which means that for the life of the coating GT0 is achieved.

What is GT0?

This is a test that looks at the adhesion of paint to steel (BS3900; Part 6). In this test the paint is cross cut to leave small squares which when tape is applied over them will rip from the steel and attach to the tape if the adhesion is not good enough. GT0 is achieved when the tape cannot remove any paint from the steel. 

Galvacoat® is a tough, single application polyurethane topcoat that’s specifically formulated to adhere to non-ferrous metals such as zinc. It is a highly cost-effective and efficient galvanising paint system that delivers perfect adhesion to hot dip galvanised steel.

 

The origins of the product lie in the need to provide long-term protection for electricity transformer tanks, and from this single application, the product has grown to be the most trusted name in painting galvanised steel.

 

It is distributed by Galco Steel Ltd. – and Wedge Group in the U.K. – both of whom have over 40 years experience in the area of galvanized steel. Our own personal experience with Galvacoat® convinced us that this was quite simply the only product on the market which did what it said when it came to providing long-life, attractive and durable cover for galvanised steel applications. galvanized paint 

Galvacoat® delivers an absolutely first class aesthetic finish on Hot Dip Galvanised Steel surfaces. We can match any RAL or British Standard colour, so the paint finish can provide a seamless continuation of your client’s brand colours or the overall design theme of the overall project. Galvacoat® galvanized paint also retains its original colour to within 5% over a period of 20 years, so you can be confident that the colour you’ve chosen will not be overly affected by atmospheric or other conditions. 

Galvacoat® delivers an absolutely first class aesthetic finish on Hot Dip Galvanised Steel surfaces, It has been designed exclusively for use on non-ferrous metals, and can be applied in a single coating – without the need for special etch primers. It delivers exceptional adhesion and does not allow any salts to form, thus maximising adhesion levels and delivering a quality coating that can be typically expected to last for up to 15 years.

 

Requiring just a single coat and suitable for all spray systems or brush applications, the lifetime cost of Galvacoat® is drastically lower than conventional paints. We can match any RAL or British Standard colour, and Galvacoat® retains its chosen colour to within 5% over a period of 20 years. It can be applied directly to freshly galvanised steel or as a fresh coat to galvanised steel that’s been coated with conventional paints.

 

You can use Galvacoat® galvanized paint on applications as diverse as balconies and gates, power and sub-station equipment, railings, street furniture, structural steel and water treatment plants.

Galvacoat® is a long-lasting and cost-effective solution for utility companies, delivering the value for money that they demand and the reduced level of re-coating that makes so much sense when dealing with a large portfolio of installations.

 

Galvacoat® galvanized paint is the ideal solution for applications as diverse as pylons, water treatment plants, gates, power and sub-station equipment, railings, street furniture and structural steel installations.

If you’re a galvanizing company in mainland Europe (with the exception of Ireland and the U.K.), you are ideally positioned to become a distributor of Galvacoat® galvanized paint We are a full service provider for our distributors, including technical expertise, shipping and logistics. There is a huge level of opportunity throughout Europe for a paint system that’s been specifically designed to deliver perfect adhesion to Hot Dip Galvanized Steel. 

With Galvacoat®, you save time and money by removing the need for costly etch primers and T washes, yet still achieving perfect adhesion to hot dip galvanised steel. Also, the lifetime cost of coating is more attractive than with traditional methods.

 

Offering exceptional wear for up to 15 years, it’s the ideal answer when the quality of the finish is important – particularly for high-end or prestige installations.

 

And apart from protecting galvanised steel, Galvacoat® also protects your reputation by offering the longest lasting and highest quality finish on the market. The lifetime cost of Galvacoat® just cannot be beaten by any other paint product.

So when repeat business is important, make sure you opt for the paint system with reassurance built in!

For your larger customers, the lifetime cost of coating is obviously of maximum importance. With Galvacoat®, you save time and money by removing the need for costly etch primers and T washes, yet still achieving perfect adhesion to hot dip galvanised steel.

 

Using the only paint system that delivers perfect adhesion to hot dip galvanised steel.

 

It’s also the ideal solution for larger applications where powder coating won’t work. Quite simply, there is no limit to the size of the project that you can undertake with Galvacoat.

Because it is formed by dipping steel in molten zinc, all parts of the surface of the steel are coated – inside, outside, awkward corners, and narrow gaps which would be impossible to protect in any other way. The coating actually tends to build up at vital corners and edges – rather than thinning out as do brushed, sprayed and other dipped coatings.

Galvanized coatings protect steel in three ways.

  • The coating weathers at a very slow rate giving a long and predictable life.
  • The coating corrodes preferentially to provide cathodic (sacrificial) protection to any small areas of steel exposed through drilling, cutting or accidental damage; scratches are sealed by weathering products from the zinc.


Cathodic (sacrificial) protection
Zinc corrodes in preference to steel and sacrifices itself to protect the steel. If the steel is damaged the corrosion products from the zinc are deposited on the damaged area resealing it from the atmosphere and therefore preventing the sideways creep of corrosion. Hot Dip Galvanizing differs from paints in this respect as most paints give no protection at points of damage and only provide barrier protection.

  • If the damaged area is larger, the sacrificial protection prevents the sideways creep of rust which can undermine paint coatings.
