That's an excellent and very important question! Rust is the number one enemy of metal outdoor furniture, and your concern is completely valid. I'm happy to walk you through the detailed, multi-stage coating process we use specifically to combat corrosion and ensure our benches last for years.
First, the foundation is the metal itself. Our benches are typically constructed from heavy-gauge steel that is often hot-dip galvanized. This means the steel is immersed in a bath of molten zinc, which forms a metallurgical bond. This zinc layer acts as a sacrificial anode, meaning it will corrode before the steel does, providing a robust first line of defense even if the surface coating gets scratched.
The core of our finish is the powder coating process. Here’s how it works:
1. Pre-treatment & Cleaning: The metal frame is thoroughly cleaned and treated with a phosphate wash to remove any oils, dirt, or residues. This creates the perfect, clean surface for adhesion.
2. Powder Application: A dry, free-flowing powder (composed of finely ground particles of pigment and resin) is electrostatically sprayed onto the metal. The charged particles are attracted to the grounded frame, ensuring an even coat on all surfaces, including edges and hard-to-reach areas.
3. Curing: The coated frame is moved into a curing oven. The heat causes the powder to melt, flow, and chemically cross-link to form a smooth, durable, and uniform plastic-like skin. This finish is far thicker and more resilient than traditional liquid paint.
The result is a hard, waterproof, and UV-resistant shield that is highly resistant to chipping, scratching, and fading. It’s this combination of galvanization (where applicable) and a high-quality thermoset powder coat that allows our benches to withstand rain, sun, snow, and the general wear and tear of outdoor use. We stand behind this process, which is why our benches come with extensive warranties against rust and corrosion. You can invest with confidence!
