Frequently Asked Questions

Q1: Will Corten steel rust and stain my patio?

A: Yes, during the initial weathering phase (the first few months), there may be some light rust seepage. To protect light-colored surfaces, we recommend placing planters on stands, using drip trays, or choosing pre-weathered or sealed surfaces. Once a stable rust layer has formed (6–12 months), the rust seepage will stop.

Q2: Do the Corten planters need liners?

A: For most outdoor plants, liners are not necessary. Weathering steel is safe for direct contact with soil. However, if you plan to move the planters frequently or wish to protect sensitive root systems, we recommend using removable plastic liners.

Q3: How do I clean the planter?

A: The Corten steel requires no cleaning. If debris accumulates, simply rinse with water. Do not use scouring pads or chemical cleaners.

Q4: Can it be used indoors?

A: Yes, but we recommend choosing a sealed surface to prevent rust dust or seepage. When using indoors, please plug the drainage holes or use a liner and tray.

Q5: What is the approximate capacity?

A: Approximately 30–35 liters (depending on the thickness of the drainage layer).

Q6: What is the steel thickness?

A: The standard thickness is 2.0 mm to 3.0 mm, offering excellent rigidity and durability. Thicker specifications are available for commercial use.

Q7: Can the dimensions be customized?

A: Absolutely. We offer custom sizes, shapes (round, rectangular, conical), and surface finishes.

Q8: What is the weight when filled with soil?

A: Approximately 50–70 kg, depending on soil moisture content. Please have two people handle it when fully loaded.
