You're right to ask about chipping—it's a common concern for outdoor furniture. Our park benches resist chipping not by magic, but through a meticulous, multi-stage powder-coating process. It starts with intensive surface preparation. Each bench undergoes abrasive blasting and chemical pretreatment to remove all contaminants, creating an immaculately clean, profiled surface that the powder can mechanically grip onto.
Next, we electrostatically apply a dry powder composed of finely ground pigment and resin particles. The charged particles wrap evenly around the entire metal frame, including edges and hard-to-reach areas. This is key—unlike liquid paint, which can drip or pull away from edges, the powder creates a uniform layer.
The real transformation happens in the curing oven. Here, the bench is heated to around 400°F (204°C). The powder particles melt, flow together, and then chemically cross-link as they cool. This creates a single, continuous plastic-like skin that is bonded to the metal. The result isn't just a layer of paint; it's a new, resilient coating.
This thermoset finish is inherently tougher than conventional paint. It flexes with the metal, resisting impact from debris or tools. Its uniform thickness prevents weak spots. Think of it like a durable shell: instead of chipping off in flakes, the cohesive coating can withstand significant stress, maintaining its integrity and protecting the bench beneath for years with minimal maintenance.
