Measuring Paint and Protective Coatings on Galvanized Steel
Galvanized steel is widely used in Malaysia because of its excellent corrosion resistance and long service life. It is commonly found in construction projects, steel structures, roofing systems, electrical cabinets, guardrails, industrial equipment, and outdoor infrastructure.
To further improve durability and appearance, galvanized steel is often painted or powder coated. Ensuring the correct coating thickness is essential for long-term protection and product quality. The Landtek CM-8820 Coating Thickness Meter provides a reliable solution for measuring dry coating thickness on ferrous (steel) substrates, making it an excellent tool for quality control and inspection.
Why Measure Coatings on Galvanized Steel?
Although galvanized steel already has a protective zinc layer, additional paint or powder coating is often applied to increase corrosion resistance and enhance appearance.
If the coating is too thin, moisture and chemicals may penetrate the protective layer, reducing the lifespan of the product.
If the coating is too thick, it can lead to cracking, peeling, blistering, poor adhesion, and unnecessary coating costs.
Routine coating thickness inspection helps manufacturers maintain consistent product quality and meet customer specifications.

Best Practices for Measuring Galvanized Steel
To obtain reliable measurement results, follow these recommendations:
1. Ensure the Surface is Clean
Remove dust, oil, moisture, and loose contaminants before taking measurements.
2. Measure After the Coating Has Fully Cured
The CM-8820 measures dry coating thickness and should be used only after the paint or powder coating has completely cured.
3. Measure Multiple Locations
Take readings at different points across the surface to ensure coating consistency.
4. Calibrate Before Inspection
Always calibrate the instrument according to the manufacturer's instructions before use.
5. Keep Proper Inspection Records
Recording coating thickness data helps support quality assurance, production control, and customer documentation.
