The ADEZZ Corten Steel CONIC Planter brings a bold, tapered silhouette to contemporary gardens, courtyards, and architectural landscapes. Its conical form creates a strong sculptural presence, making it ideal for feature planting where proportion, materiality, and scale matter. The weathering corten steel finish develops a rich, natural patina over time, adding warmth and texture while providing exceptional durability in UK conditions.

The CONIC Planter is available in 11 substantial sizes, including D120cmxH100cm, D120cmxH80cm, D120cmxH60cm, D100cmxH100cm, D100cmxH80cm, D100cmxH60cm, D80cmxH100cm, D80cmxH80cm, D80cmxH60cm, D60cmxH80cm, and D60cmxH60cm. These generous dimensions make the CONIC suitable for everything from specimen trees and architectural shrubs to layered planting schemes in commercial and residential settings.

Use the ADEZZ Corten Steel CONIC Planter to create striking focal points, anchor entranceways, or punctuate terraces and plazas. The tapered profile naturally draws the eye upward, enhancing vertical planting and making it particularly effective for sculptural trees and structured planting designs. Its robust construction and integrated drainage ensure long-term performance in demanding landscape projects.

ADEZZ manufactures its Corten Steel planters from a specialist steel alloy that naturally protects itself from corrosion. When you place the planter outdoors, oxygen and moisture react with the steel to form a stable protective rust layer. This layer seals the surface and prevents deeper corrosion, keeping the planter strong and structurally sound for many years.

ADEZZ supplies all Corten Steel planters rust-free. Once you expose the planter to the elements, the weathering process begins and usually takes 4 to 5 months, depending on rainfall, temperature, and exposure. During this time, the colour changes from dark grey to warm orange-brown, then settles into the rich natural patina that designers and landscapers value.

As the steel weathers, rust runoff can temporarily stain paving or stone. You can prevent marking by placing the planter on gravel, soil or another permeable surface until the patina stabilises.

ADEZZ fits every Corten Steel planter with hidden feet and drainage holes. These raise the planter slightly above the ground, allowing air to circulate underneath and water to drain away freely. This design protects the base and supports healthy root growth.

Install the planter on a flat, solid surface and leave at least 1cm of space around the base so moisture cannot become trapped. Do not fit an overflow pipe, as standing water inside the planter can accelerate corrosion.

When you plant, add a 10cm layer of gravel to the base, cover it with a permeable membrane, then add your compost or growing medium. This setup ensures excellent drainage and prevents excess moisture from reaching the steel.

Avoid using hydro pellets, as they retain water and reduce drainage efficiency. For best results, avoid placing Corten Steel planters in areas with heavy salt exposure, such as near the coast.

Once the planter has developed its final patina, you can leave it to weather naturally, or apply a rust stabiliser (Owatrol) to lock in the colour and prevent loose rust from transferring.

With proper installation and drainage, ADEZZ Corten Steel planters deliver a robust, low-maintenance, weatherproof planting solution that performs beautifully year after year.

Riverhill Garden Supplies — ADEZZ Specialist (UK)

In 2011, Riverhill Garden Supplies became the first business in the UK to retail ADEZZ products through the then sole importer, The Pot Company. Since 2019, we have worked directly with ADEZZ to supply their full range to customers across the UK.

More than just an online retailer
We operate as more than just an online retailer. From our Kent warehouse we handle extra-large orders, bespoke fabrications and phased or delayed deliveries. We regularly store planters for customers until sites are ready and then arrange tailored deliveries to suit contractors, designers and private clients. We keep our approach simple by combining flexibility, practical problem-solving and clear communication.

Ordering direct from ADEZZ (Uden, Holland)
As a dedicated ADEZZ partner, Riverhill Garden Supplies combines deep product knowledge, accurate lead time advice and dependable customer service. We place orders directly with ADEZZ’s central warehouse in Uden, Holland, often daily during the high season, which allows us to secure stock immediately or instruct fabrication to begin without delay when ADEZZ needs to make a product to order.

Why we choose ADEZZ
We choose to list ADEZZ products because their European craftsmanship, precision fabrication and durable finishes meet the standards we demand for our customers. ADEZZ designs Aluminium and Corten Steel planters that combine clean contemporary design with professional-grade construction, making them suitable for everything from private gardens to large commercial landscapes.

Why ADEZZ Corten Steel stands apart
Corten Steel planters are one of the most poorly replicated products in the planter industry, with many cheaper alternatives failing to match proper steel grade, welding quality and long-term performance. ADEZZ uses high-grade 3mm Corten Steel (S355JOWP) and applies precision welding, accurate forming and strict quality control. This approach ensures every planter weathers evenly, forms a proper protective patina and remains structurally sound for decades. You can see the difference in the finish, strength and consistency of every ADEZZ Corten Steel planter.

How ADEZZ compares to UK-made alternatives
We regularly speak with UK manufacturers who offer Aluminium, Corten Steel, Fibreglass, Hardwood and coated steel planters that attempt to copy ADEZZ designs. None of them match the welding quality, surface finish or long-term durability that ADEZZ consistently delivers.

ADEZZ also holds an extensive range of stock at its warehouse in Uden, Holland, which allows us to offer fast, reliable order fulfilment across hundreds of sizes, colours and designs — something UK manufacturers simply cannot replicate. Over the years, we have imported planters from further afield. While this sometimes reduced costs, it also confirmed what we already knew: quality suffered. Inferior coatings, thinner steel and inconsistent fabrication produced planters that failed to meet our standards, especially in Corten Steel and Aluminium.

ADEZZ remains our benchmark
These experiences continue to reinforce our view that ADEZZ sets the benchmark for European-made planters. Their craftsmanship, consistency and reliability stand apart across Aluminium, Corten Steel, Hardwood, Fibreglass and coated steel ranges.

Experienced UK ADEZZ reseller
Whether you need modern Aluminium planters, premium Corten Steel designs or bespoke ADEZZ fabrications, Riverhill Garden Supplies provides one of the UK’s most experienced and reliable ADEZZ services, delivering clear advice, accurate lead times and dependable delivery from order to installation.

Use the ADEZZ Corten Steel CONIC Planter to create bold specimen planting that anchors a space with scale and structure. In the larger sizes, such as D120cmxH100cm and D100cmxH100cm, plant multi-stem trees such as Amelanchier, Betula, Cornus, or olive trees to introduce height, movement, and strong seasonal interest. The tapered form naturally elevates the planting, giving trees a sculptural, architectural presence.

Create a strong evergreen structure with clipped shrubs such as Ilex crenata, yew, bay, or compact Viburnum. Repeat CONIC planters along entrances, terraces, or pathways to frame spaces, guide movement, and define zones in contemporary gardens, commercial landscapes, and hospitality settings.

Introduce texture and movement with ornamental grasses such as Miscanthus, Calamagrostis, Panicum, or Pennisetum. These soften the bold corten steel form while maintaining an architectural feel. Underplant with long-flowering perennials such as Salvia, Nepeta, Echinacea, Geranium, or Verbena to extend seasonal colour and support pollinators.

For UK-native and Kent-focused schemes, plant native shrubs such as Cornus sanguinea, Viburnum opulus, and compact hawthorn, along with native grasses and perennials such as Deschampsia, Achillea, and Knautia. It creates resilient, low-maintenance planting that suits public realm and ecological landscapes.

Use the smaller sizes, such as D60 cm x H60 cm and D80 cm x H60 cm, for layered shrub and perennial mixes on terraces, balconies, and courtyards. Group multiple CONIC planters to create rhythm, zoning, and visual impact while retaining layout flexibility.
