The Beauty of Weathering Steel
Corten steel is a specially formulated alloy that forms a stable, protective rust layer when exposed to the elements. Unlike ordinary steel that continues to corrode, weathering steel develops a dense oxide coating that actually protects the underlying metal from further deterioration. The result is a beautiful, ever-changing patina in rich shades of orange, rust, brown, and bronze that deepens and matures over time. This living finish ensures your fountain becomes more beautiful and characterful with age, making it a truly unique piece that tells a story.

The Patina Process:
When first installed, your Corten steel urn will have a mill finish or light surface rust. Over the following weeks and months, exposure to moisture and air will accelerate the patina development. The steel will progress through various shades of orange and rust before settling into deep, rich browns and bronzes. The patina typically stabilizes within 6-12 months, though it will continue to subtly evolve over the years. Seasonal weather changes, water chemistry, and environmental conditions all influence the final appearance, ensuring your fountain is truly one-of-a-kind.

Installation Considerations:
Corten steel urns can be installed as standalone fountain features or integrated into existing pond systems. A submersible pump (not included) is required to create the water flow. The pump should be sized appropriately for your chosen urn size - larger urns require higher GPH (gallons per hour) ratings for optimal water display. Professional installation is recommended to ensure proper pump sizing, secure placement, electrical connections, and optimal water flow.
Important Note: During the initial patina development phase (first few months), the urn will shed rust particles that can stain surrounding surfaces. We recommend placing the urn on a surface that won't be damaged by rust staining, or using a protective barrier during the initial weathering period. Once the patina stabilizes, rust shedding will significantly decrease.
Care and Maintenance:
Corten steel requires minimal maintenance. The rust patina is self-protecting and needs no special treatment. Simply allow the natural weathering process to occur. You can periodically rinse the urn with water to remove debris or mineral deposits. The patina may lighten slightly when wet and darken again as it dries - this is normal. Regular pump maintenance includes cleaning the intake screen and checking water levels. In freezing climates, drain the urn and remove the pump for indoor storage during winter months.
Frequently Asked Questions
Q: What is Corten steel and how is it different from regular steel?
A: Corten steel, also known as Corten or weathering steel, is a specially formulated steel alloy containing copper, chromium, and nickel. Unlike regular steel that rusts and deteriorates, Corten steel forms a stable, protective oxide layer (rust patina) that actually prevents further corrosion. This dense rust coating acts as a barrier, protecting the underlying metal while creating a beautiful, warm finish in shades of orange, rust, and bronze. Regular steel would continue to rust and eventually fail, but Corten steel's patina is self-protecting and permanent, making it ideal for outdoor sculptures and water features.
Q: Will the rust patina stain my patio or surrounding area?
A: During the initial weathering phase (typically the first 3-6 months), the urn will shed rust particles that can stain concrete, stone, or other porous surfaces. This is a normal part of the patina development process. We strongly recommend placing the urn on a surface that won't be damaged by rust staining, or using a protective barrier (such as a rubber mat or sacrificial stone base) during this initial period. Once the patina fully stabilizes, rust shedding will dramatically decrease, though some minimal staining may still occur during heavy rain. Many designers embrace this as part of the aesthetic, allowing the rust to naturally stain the surrounding area for an integrated, organic look.
Q: Which size should I choose for my space?
A: The 30" urn is perfect for smaller ponds, compact gardens, patios, and intimate spaces where you want a substantial fountain without overwhelming the area. The 36" urn is our most versatile size, working well in medium-sized ponds, standard water gardens, and as a focal point in most residential landscapes. The 42" urn creates dramatic impact and is ideal for large ponds, expansive landscapes, commercial installations, or when you want the fountain to be a commanding presence. Consider both your available space and the visual weight you want the fountain to carry. Larger urns also require more powerful pumps for optimal water display.
Q: Is a pump included with the urn?
A: No, pumps are not included with the Corten steel urns. This allows you to select the appropriate pump based on your specific installation requirements and desired water flow. For the 30" urn, we recommend a pump rated at 1200-1500 GPH. For the 36" urn, use 1500-2000 GPH. For the 42" urn, choose 2000-2500 GPH. The exact pump size will depend on your installation setup, water depth, and desired fountain height. We're happy to help you select the right pump for your specific needs, or consult with a professional installer for optimal results.
Q: How long does it take for the patina to fully develop?
A: The patina development process varies based on climate, weather exposure, and environmental conditions. In most climates, you'll see significant color development within the first 2-4 weeks, with the patina continuing to deepen over 6-12 months. Areas with high humidity or frequent rain will develop patina faster than dry climates. The urn will progress through various shades - starting with bright orange rust, transitioning through reddish-brown tones, and eventually settling into rich chocolate browns and bronzes. Even after the initial stabilization, the patina will continue to subtly evolve over the years, responding to seasonal changes and creating a living finish that tells a story.
Q: Can I leave this fountain outside in winter?
A: Yes, the Corten steel urn itself is extremely durable and can remain outdoors year-round in all climates. The weathering steel is designed to withstand freeze-thaw cycles without damage. However, you must remove the pump and drain all water from the urn before freezing temperatures arrive. Water left in the urn can freeze and potentially cause damage. Remove the pump and store it indoors in a dry location for the winter. Drain the urn completely and ensure no standing water remains. The urn can stay in place and will continue to develop its patina through the winter months. In spring, simply reinstall the pump and refill.
Q: Will the rust patina continue to get darker over time?
A: The patina will deepen and mature over the first 6-12 months, transitioning from bright orange rust to rich browns and bronzes. After this initial stabilization period, the color will remain relatively consistent, though it will continue to subtly evolve over the years. The patina may appear lighter when wet (from rain or fountain operation) and darker when dry - this is completely normal. Seasonal variations in weather and humidity can also cause slight color shifts. Some areas of the urn may develop darker or lighter patches based on water flow patterns and exposure, adding to the unique character of each piece. This natural variation is part of the beauty of weathering steel.
Q: Is any special maintenance required for Corten steel?
A: Corten steel is remarkably low maintenance. The rust patina is self-protecting and requires no sealing, painting, or special treatments. Simply allow the natural weathering process to occur. You can periodically rinse the urn with clean water to remove debris, algae, or mineral deposits from the fountain operation. Avoid using harsh chemicals, abrasive cleaners, or wire brushes that could damage the protective patina layer. The only regular maintenance required is for the pump system - clean the pump intake screen regularly, maintain proper water levels, and follow standard pump care procedures. The beauty of Corten steel is that it's designed to rust, so there's no need to fight the natural aging process.
Note: Each Corten steel urn develops a unique patina based on environmental conditions, water chemistry, and weather exposure. Actual finish will vary from photos shown. Initial rust shedding is normal during the first several months.
