Galvanised Steel Paints
Direct-to-galvanised steel paints are designed for application directly onto galvanised surfaces without requiring a primer. These paints are formulated to adhere effectively to zinc coatings, providing protection against rust and corrosion. Ideal for industrial environments, they are commonly used on galvanised steel fences, handrails, and equipment. To ensure optimal adhesion and performance, the galvanised steel surface must be thoroughly cleaned to remove grease, dirt, or any zinc salts that may have formed, which can prevent proper paint bonding. Contact technical support for product compatibility.

What Are Direct-to-Galvanised Steel Paints?
Direct-to-galvanised steel paints are specialist coatings designed to be applied directly onto galvanised steel without needing a separate primer. These paints offer exceptional adhesion to the zinc layer found on galvanised steel, which is often a challenging surface to paint due to its slick nature. The formulation ensures a robust and long-lasting finish, protecting against corrosion, UV exposure, and wear, making it a preferred choice for both industrial and commercial applications.
Why Are They Used?
Galvanised steel is widely used in industries due to its strong resistance to rust and corrosion. However, over time, the zinc coating can deteriorate, exposing the steel to environmental factors that can lead to rust. Direct-to-galvanised steel paints are used to prevent this degradation and extend the lifespan of galvanised structures. These paints are also used to enhance durability in high-traffic or high-wear environments where additional protective layers are necessary. The use of a specialist paint designed for galvanised surfaces ensures proper adhesion and long-term performance.
Where Are They Used?
Direct-to-galvanised steel paints are ideal for a range of applications, particularly in environments where galvanised steel is exposed to weathering and harsh conditions. They are commonly used on:
- Galvanised steel railings and fences
- Outdoor structures such as lamp posts, pylons, and gates
- Steel-clad buildings, agricultural equipment, and industrial machinery
- Handrails, ladders, and safety structures in commercial settings
These coatings are essential in sectors such as construction, agriculture, and manufacturing, where corrosion prevention is critical.
Importance of Cleaning Galvanised Steel
Before applying direct-to-galvanised steel paints, proper surface preparation is essential. Galvanised steel can accumulate dirt, grease, and, more importantly, zinc salts, which are by-products of the galvanisation process. These substances can create a barrier that prevents the paint from adhering properly to the steel. Cleaning the surface thoroughly with suitable degreasers or solvents ensures that all contaminants are removed, improving paint adhesion and the overall longevity of the coating. This step is crucial for achieving the full benefits of the specialist paint.
