Coating for Galvanised Steel
Choosing the correct coating for galvanised steel is essential for achieving strong adhesion, long-term corrosion protection, and a durable finish. At Industrial Coatings Ltd, we supply specialist coating systems designed for galvanised steel used across industrial, commercial, and construction environments throughout the UK.
Galvanised steel already provides corrosion resistance through its zinc coating, but additional protective coatings are often required to improve durability, appearance, UV resistance, and long-term performance. Using the wrong paint system can lead to peeling, flaking, and adhesion failure, especially on newly galvanised surfaces.
What Is Galvanised Steel?
Galvanised steel is steel coated with zinc to help protect against rust and corrosion. It is widely used across the UK for:
- Roofing and cladding
- Structural steel
- Gates and railings
- Agricultural buildings
- Industrial units
- Warehouses and factories
- Steel fabrication
- Pipework and infrastructure
Additional coating systems are commonly applied to galvanised steel to increase weather resistance and improve appearance.
Best Coatings for Galvanised Steel
At Industrial Coatings Ltd, we supply coatings suitable for both new and weathered galvanised steel surfaces, including:
- Galvanised steel primers
- Epoxy coatings
- Polyurethane topcoats
- Direct to metal coatings
- Zinc rich primers
- Industrial metal paints
These systems are designed to provide excellent adhesion and long-term protection in harsh industrial and external environments.
Why Surface Preparation Matters
Galvanised steel can be difficult to coat without proper preparation. Oils, oxidation, smooth zinc surfaces, and contaminants can prevent coatings from bonding correctly, leading to premature coating failure.
Preparation methods may include:
- Degreasing and cleaning
- Abrasion or sweep blasting
- T wash or mordant solution treatment
- Removal of white rust and oxidation
- Application of specialist primers
Correct preparation helps create a mechanical key for improved coating adhesion.
