Henderson Garden Supply Raised Garden Bed Planter

Weathering steel, often known as CorTen, is a specialized alloy designed to form a stable, rust-like appearance when exposed to the elements. This natural patina acts as a protective layer, preventing further corrosion and ensuring the planter remains durable for years.

No, these panels are engineered for structural integrity and should not be cut or rejoined. Because of the 2mm thickness and reinforced top edge, modifying the panels will compromise the Zero Flex system and void the structural design.

The 2mm panel thickness and 8mm top lip provide significant rigidity, but for larger configurations, we recommend using the included bracing options. These ensure the walls remain perfectly straight and withstand the pressure of the soil over time.

The corner pieces are designed to facilitate precise 90-degree bends, measuring 4 inches on each side. They lock into the modular panels to create a clean, seamless transition that maintains the planter's structural stability.

Assembly is straightforward, though it does require basic tools and a bit of patience. Because the system is modular, you simply align the panels and corner pieces according to your layout, ensuring all braces are secured for maximum rigidity.

Yes, as the steel develops its patina, runoff may occur during the initial weathering process, which can stain porous surfaces like concrete or stone. We recommend placing the planter on grass, gravel, or a protective mat until the patina has fully stabilized.
