Powder coating is a high-performance finishing process that applies a dry, electrostatically charged powder to metal surfaces. Once heat-cured, it forms a smooth, durable, and corrosion-resistant finish. At NZG, we use powder coating to protect and enhance edge protection barriers, fixings, and steel components for long-lasting performance.
Powder coating works by applying an electrostatically charged powder to a pre-treated metal surface. The powder sticks to the grounded metal and is then baked at high temperature, melting into a tough, even layer. At NZG, this process ensures superior resistance to impact, abrasion, and weathering for every coated component.
Powder coating offers superior durability, longer lifespan, and a more consistent finish compared to traditional paint. It resists chipping, fading, and corrosion while providing a wide range of colours and textures. At NZG, our powder coating process also reduces environmental impact and maintenance costs.
Yes, powder coating adheres well to zinc electroplated surfaces, the combination of the two coatings gives exceptional corrosion protection. If the powder coating is chipped or damaged, the underlying zinc electroplating prevents the steel surface from rusting and undermining the powder coating around the damaged area.
Yes, powder coating is one of the most sustainable metal finishing methods available. It contains no solvents or toxic chemicals, produces minimal waste, and allows unused powder to be recycled. NZG’s powder coating process fully complies with UK environmental regulations and supports sustainable construction practices.
Powder coating works best on conductive metal surfaces such as steel, aluminium, and iron. Non-metal materials like plastic or wood generally cannot be powder-coated because they don’t conduct electricity or withstand curing temperatures.
