Most people don’t give much thought to how a roller shutter stays looking good or working properly over time – until it doesn’t. At Superior Load Cover, we do. Because when a surface finish fails, it doesn’t just look bad. It lets in rust, weakens parts, and shortens the life of the entire system. That’s why we take surface treatment seriously. Every slat, rail, bracket and bolt is built to last, and that durability starts with three key processes: powder coating, anodizing, and galvanizing. These aren’t just technical extras – they’re critical to making sure our products survive years of hard use in real-world conditions.
Powder Coating: Where Looks Meet Longevity
Powder coating is a process where dry particles of pigment and resin are electrostatically sprayed onto metal, then baked in an oven to form a tough, uniform finish. It’s far more durable than regular paint and gives the surface extra resistance to chips, scratches, UV damage, and corrosion. At Superior Load Cover, we’ve taken it a step further. We worked with industry experts to create a custom matte black powder coating that’s developed specifically for our products. It’s harder than standard finishes, better at resisting scratching, and designed to handle heat, dust, salt and rough conditions without flaking or fading. You’ll notice it right away in the clean, consistent finish – and even more in a few years when it still looks the same.
Anodizing: Invisible Strength for Aluminium
Some of the most important parts of our roller covers are made from aluminium because it’s strong but lightweight – perfect for sliding slats and trim components. But raw aluminium needs protection, and that’s where anodizing comes in. It’s an electrochemical process that converts the surface of the metal into a hard oxide layer. Unlike a coating that can peel off, this layer becomes part of the aluminium itself. It makes it tougher, more resistant to wear and corrosion, and ideal for parts that need to move, lock, or take contact every day. Anodized components stay sharp, don’t flake, and hold up in wet or coastal conditions. They’re built for life on the move.
Galvanizing: Protection Where It Counts
Steel is unmatched for strength, especially in brackets, rails and load-bearing hardware. But it needs protection from rust, especially in high-impact or hidden areas where moisture and grit tend to collect. We galvanize our steel components using a hot-dip process that coats them in zinc. This sacrificial layer corrodes instead of the steel, extending the life of each part even if it gets scratched. It’s not the flashiest process, but it’s one of the most important. Galvanized steel stays strong in mud, rain, road salt and heavy-duty use – exactly what you want when the going gets rough.
Why It Matters
Anyone can bolt together a roller shutter and call it tough. But without the right surface protection, it won’t stay that way. We’ve seen it all – cheap powder flaking off, bare aluminium oxidising, uncoated steel rusting from the inside out. That’s why we don’t cut corners. Every finish we use is chosen because it works. Because we’ve tested it. Because we’ve had to fix the failures other brands don’t want to talk about.
So when you choose Superior Load Cover, you’re not just buying a product that looks good out of the box. You’re getting something built to survive real life – the dust, the salt, the knocks, the weather, the long hauls. Whether you’re running a fleet, working in the bush, or just loading up for the weekend, you can count on every surface, every component, and every detail to do its job.
That’s durability by design. That’s Superior Load Cover.
