Absolutely, we can make a planter box shaped like a rectangle with rounded corners. This is one of the most popular custom shapes we produce, and it offers a perfect balance between modern geometry and soft, approachable aesthetics. Let me walk you through exactly how we achieve this in our factory.

First, the design phase. When you request a rectangular planter with rounded corners, we don’t just guess the radius. Our engineering team works with you to determine the exact corner radius—whether you want a subtle 10mm curve or a bold 50mm sweep. We build a 3D model of your planter, allowing you to visualize how the rounded corners will look from every angle. The model also ensures that the thickness of the walls remains consistent, which is critical for durability and visual appeal.

Second, fabrication. Depending on the material you choose—steel, aluminum, or Corten—we use different techniques. For metal planters, we use precision laser cutting to create the side panels. The laser cutter can follow any corner radius with incredible accuracy, down to fractions of a millimeter. After cutting, we bend the panels to the correct angle, and then we weld the corners. But here’s the key: because the corners are rounded, we don’t weld a sharp seam. Instead, we either use a smooth continuous bend (if the radius is large enough) or we weld and grind the joint to create an invisible, seamless curve. The result is a flawless rounded corner that looks and feels premium.

Third, finishing. Once the planter is welded and cleaned, we move to finishing. If you want a raw Corten look, we accelerate the rust patina. If you prefer powder coating, we apply a primer and then a durable finish in any RAL color. The rounded corners actually help the coating adhere better because there are no sharp edges where paint can chip away. We also add drainage holes, optional liners, and protective feet, all while maintaining the rounded rectangle shape.

So, to answer your question directly: yes, our factory specializes in custom shapes, and rounded-corner rectangles are a standard specialty. We have manufactured hundreds of planters in this exact style, ranging from small tabletop versions to massive outdoor statement pieces. The minimum order quantity is flexible, and we can even do a single prototype if you want to test the design.

In summary, if you need a planter box that is a rectangle with rounded corners, we are fully equipped to make it. Send us your dimensions, choose your material, and we’ll take care of the rest. You’ll receive a precisely fabricated, high-quality planter that stands out for its clean lines and gentle curves. Contact our factory today to start your custom order.
