Rust can be a major issue for metal surfaces exposed to moisture and harsh environmental conditions. Over time, rust weakens the structural integrity of metals, leading to costly repairs or replacements. One highly effective way to protect metal surfaces from rust is through powder coating. In this blog, we’ll explore how it works.
Powder coating involves applying a dry powder composed of resins and pigments onto metal surfaces. This powder is electrostatically charged, allowing it to adhere evenly to the metal surface before being heated in an oven. The heat melts the powder, forming a seamless, durable coating that bonds tightly to the metal.
This process creates an airtight barrier between the metal and its environment, preventing moisture, oxygen and other rust-causing elements from reaching the metal. This protective layer is thicker and more durable than traditional paint, making it highly resistant to peeling, chipping and other types of surface damage that could expose the metal to rust.
Steel, being highly susceptible to rust, is one of the metals that benefits most from powder coating. One common question people ask is, “Does powder-coated steel rust?” While powder coating significantly reduces the chances of rust forming on steel, it doesn’t make steel entirely rust-proof.
It does offer strong protection, but if the coating gets damaged through scratches or impact, the exposed steel underneath may rust over time. Regular inspections and timely maintenance will keep your powder-coated steel protected.
Aluminium is often thought of as rust-resistant because it doesn’t contain iron, the metal that reacts with water and oxygen to form rust. However, aluminium is still vulnerable to corrosion, particularly in coastal environments or areas with high humidity and salt exposure. Powder coating provides an extra layer of defence against corrosion.
So, if you’re still wondering, “Does powder-coated aluminium rust?” technically, it doesn’t. However, powder coating enhances its natural resistance to corrosion by forming a tough, durable coating that shields it from environmental elements. This makes powder-coated aluminium an excellent choice for outdoor applications, such as fences, gates and patio furniture.
