The Onxy (CNX) is a sophisticated addition to our premium collection of outdoor furnishings. This contemporary bowl shaped planter serves as an architectural statement piece wherever it is placed. Whether you are looking to define a walkway or create a focal point on a patio, this item delivers both visual appeal and structural integrity.
Every detail of this design is carefully considered to provide the perfect environment for planting trees, shrubs, and ornamental foliage. The inherent strength of the construction ensures that it remains a long-lasting performance piece when placed in demanding outdoor environments. You will find that this vessel effortlessly creates an eye-catching display that matures in beauty over time.
Our planter boxes are precision manufactured using 2mm thick Corten steel, a material renowned for its exceptional resilience. This steel is specifically formulated to form a protective layer of rust upon its surface when exposed to the elements. This oxidation process not only provides a unique, rustic aesthetic that blends perfectly with natural landscapes but also shields the underlying steel from further corrosion.
We recommend professional placement for this item, as the robust steel construction provides significant heft and long-term stability in high wind areas.
While the standard thickness is 2mm, we understand that professional projects may require additional structural rigidity. Consequently, alternative thicknesses from 3mm up to 10mm can be requested to suit specific engineering requirements or heavy duty landscaping needs. This versatility makes the Onxy (CNX) a preferred choice for landscape architects and commercial developers who demand longevity without sacrificing style.
When selecting a planter for large botanical specimens, one must consider the forces exerted by moist soil and root expansion. The bowl shape of this unit is engineered to distribute the lateral pressure of the soil evenly across the curved walls. This geometric advantage prevents the common issue of structural bulging or wall flex found in cheaper, square-sided alternatives.
The material physics of Corten steel are particularly beneficial here. Because this alloy is designed to undergo a weathering process, it possesses a high tensile strength that resists the internal torque applied by expanding root systems. The 2mm thick steel wall acts as a rigid membrane, ensuring that the volume of the container remains consistent throughout the changing seasons. The integrity of the weld points is strictly controlled to ensure that the structural load is managed correctly, even when the container is filled to its maximum capacity with saturated organic matter.
Integrating this planter into your landscape involves a straightforward yet rewarding workflow. To ensure you gain the best experience, we suggest the following steps.
The design philosophy behind this equipment prioritises safety for both the plants and the handlers. By choosing a heavy duty material, you eliminate the risk of brittle failure or cracking that can lead to debris hazards in public spaces. The weight of the steel provides a low centre of gravity, which ensures that the planter remains stable against accidental knocks or strong gusts of wind.
From an operational safety standpoint, the smooth rolled edges of the bowl design ensure that there are no sharp burrs that could injure individuals while gardening. Furthermore, the inclusion of factory-drilled drainage holes serves as a vital compliance feature for plant health. By preventing the accumulation of stagnant water, the unit reduces the risk of root rot and the subsequent development of mould or pests, which contributes to a healthier outdoor environment for staff and visitors alike.
Investing in the Onxy (CNX) represents a sound business decision for those managing commercial properties, hospitality venues, or high-end residential estates. The cost-benefit analysis is clear when considering the total life cycle of the product. Cheap, plastic, or low-grade metal containers often require replacement within two to three years due to UV degradation or rusting through.
In contrast, this Onxy (CNX) is built to last for decades. By opting for a high-quality, weather-resistant material, you reduce administrative overheads and maintenance costs associated with recurring procurement cycles. The aesthetic appeal of the developing patina actually increases in value over time, ensuring that your property maintains a premium look with minimal intervention. This asset protection is further supported by the material resistance to vandalism and incidental impacts, making it an ideal candidate for high-traffic commercial zones.
The following table outlines the standard parameters for the container. Please reach out to our team if you require custom dimensions or varying plate thicknesses for your specific architectural project.

As standard, our Corten steel containers are delivered in an un-rusted, raw state. This is intentional, as it allows the customer to witness the natural beauty of the transition. The weathering process will typically take between 4 and 5 months to complete depending on the climate and proximity to salt air or moisture.
During this period, the steel will transform from its initial grey metallic colour to a rich, warm orange-brown hue. This layer is not just a cosmetic change but a functional barrier. Once the process is complete, the surface will become stable, and the risk of rust runoff will significantly decrease. It is a natural and organic evolution that ensures your garden feature remains unique to your specific location and local environmental conditions.
We invite you to transform your outdoor space today with the timeless elegance of this piece. Whether used as a standalone sculptural element or grouped together in a series to define a space, this planter provides the durability and style required by modern landscaping standards. Should you have any questions regarding the suitability of this unit for your project, our team is always on hand to provide expert guidance on installation and long-term care.
