The ADEZZ Corten Steel CARREZ Barrier Trough delivers a strong, architectural solution for screening, division, and structured planting in both residential and commercial landscapes. Designers and landscapers use these tall troughs to create visual separation, define boundaries, and form planted screens where privacy and structure matter. The clean, linear profile and neatly folded top edge give the CARREZ Barrier Trough a confident, contemporary presence that sits comfortably alongside modern buildings, terraces, and complex landscaping schemes.

ADEZZ manufactures the troughs from high-quality corten steel for long-term outdoor performance in the UK climate. As the steel weathers, it develops a stable, protective patina that adds warmth and character while remaining low-maintenance. These are standard troughs with a base, allowing use on paved surfaces, rooftops, terraces, and areas where planting directly into the ground is not possible.

The CARREZ Barrier Trough is available in eight sizes: L80cmxD40cmxH80cm, L100cmxD40cmxH80cm, L120cmxD40cmxH80cm, L150cmxD40cmxH80cm, L200cmxD40cmxH80cm, L90cmxD30cmxH80cm, L200cmxD100cmxH80cm, and L300cmxD100cmxH80cm. These options allow you to create long screening runs, define entrances, divide courtyards, and build planted backdrops using shrubs, grasses, or structured planting.

Riverhill Garden Supplies supplies the ADEZZ Corten Steel CARREZ Barrier Trough nationwide, offering reliable UK delivery and secure project storage. Customers can order troughs well in advance and schedule delivery to align precisely with planting programmes or phased landscaping works, ensuring smooth coordination across both private gardens and commercial 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.

Stock and Lead Times

Our website displays all ADEZZ Corten Steel CARREZ, CIRCUM, CONIC, TAP, ELLIPSE, L-SHAPED, BOCCA, and ONYX planters as in stock. We do hold a limited selection of these planters at our warehouse near Tonbridge, Kent; however, the majority of orders are supplied directly from ADEZZ, who maintain high stock levels across this range.

As a general guide, the average lead time is approximately 10–12 days from order. This timeframe is indicative only and can vary depending on size, quantity, and current stock availability.

If lead time is critical to your project, or if you would like confirmation before placing an order, we strongly recommend contacting us first. A member of our team will be happy to check live stock levels with ADEZZ and provide a more accurate indication of delivery times before you proceed.

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.

Commercial planting ideas

In commercial landscapes, the CARREZ Barrier Trough works best with robust, low-maintenance planting that provides structure and consistency year-round. Evergreen shrubs such as yew, Portuguese laurel, or Prunus lusitanica create reliable screening along boundaries, walkways, and seating areas while requiring minimal ongoing care. Their upright growth habit suits long linear runs where uniformity is essential.

Ornamental grasses, widely used in commercial settings for their resilience and contemporary appearance, work well. Species such as Calamagrostis, Miscanthus, and Panicum perform well in exposed locations and provide movement without becoming visually untidy. Planted in repetition, they soften hard surfaces and add seasonal interest without compromising clean lines.

For offices, hotels, and public-facing spaces, multi-stem trees planted at intervals within the troughs create rhythm and scale. Hornbeam, Amelanchier, or birch introduce height while maintaining a light canopy that does not overwhelm surrounding architecture. Underplanting with evergreen ground cover helps reduce maintenance and keeps the planting looking intentional year-round.

Residential planting ideas

In residential gardens, the CARREZ Barrier Trough allows for more expressive and layered planting schemes while still providing screening and structure. Evergreen shrubs such as Viburnum, Pittosporum, or bay offer privacy and respond well to shaping, making them ideal for terraces and garden boundaries close to the home.

Ornamental grasses and perennials work particularly well in domestic settings, where texture and seasonal change are often more desirable. Pennisetum, Stipa, salvias, and hardy geraniums soften the strong lines of the troughs and bring colour and movement into the garden through the growing season.

For a more Mediterranean or contemporary feel, olives, olives on a stem, or compact multi-stem trees can be used as focal planting. Combined with underplanting of lavender, rosemary, or low grasses, this approach works exceptionally well on sunny patios and roof terraces, creating privacy without feeling enclosed.
