Our raised garden beds are made for you...

If you love high-end aesthetics...

One reason to love our raised garden beds is that they look very stylish – we’ve intentionally designed the range to enhance the look & feel of the gardens they feature in. Our raised garden products look so good because they’re:

  • Made from real weathering steel for a rustic natural look that develops with a rusted patina.
  • Joined via hidden flanges with pre-cut guide holes to create seemingly continuous, beautifully clean lines.
  • Precision-engineered to achieve a stylish, high-end aesthetic with every installation.
  • Designed with rolled edges for a smooth & safe profile.

If you value high-quality...

Simply put, you won’t find better quality raised garden bed panels, because Straightcurve products are:

  • Very high-quality landscaping products made to exacting standards.
  • Designed & manufactured to an exceptionally high standard for a flawless fit & finish.
  • Made from high-quality engineered weathering steel.

If you're looking for a very durable product...

Our raised garden bed products are ideal for DIY gardeners and professional landscapers who value durability because they’re:

  • Made with weathering steel; a hard-wearing material that can last for 10 years or more.
  • Rock-solid and won’t budge once installed thanks to our unique joining + fixing systems.
  • Quality tested to ensure landscape industry-leading durability.

If you like value for money...

Our raised garden bed products provide exceptional value for money because they’re:

  • Made with weathering steel which lasts longer than less robust materials such as mild steel, timber, or plastic.
  • Designed to be installed at ground level, which means you only pay for the materials you see – unlike some other brands which require one-third of the product to be buried.

If you're a bit of a perfectionist...

If you have an eye for detail and want things to be just so (and stay that way) our raised garden bed products are ideal for you because they’re:

  • Designed to fit neatly together via discreet joining systems that produce beautiful, almost seamless joins.
  • Engineered to stay strong & true for many years after installation – the quality of our steel and unique installation systems ensure our products won’t budge, bulge, or otherwise change shape once installed.

If ease of installation and usability are important to you ...

Our raised garden bed products tick all the usability boxes because they’re:

  • Expertly designed for quick & easy DIY installation.
  • Made with smooth rolled edges to keep children & pets and other garden users safe.
  • Maintenance-free once installed and weathered.

If you want to increase curb appeal and liveability...

Our raised garden bed products are easy to connect & install. They require no maintenance once installed. And they improve the look & feel of the homes, gardens, and commercial properties in which they feature. For these reasons, our products are a great low-cost, low-maintenance option for:

  • Increasing the curb appeal and liveability of homes & investment properties.
  • Making commercial buildings more attractive to tenants and their customers.
  • Introducing plants & trees to office spaces and other working environments.

The weathering steel finish


How it comes

The manufacturing process of weathering steel will leave the surface in a dark, almost black state. The weathering process sees this layer break down first before the desired protective patina layer can establish.


What it turns into

Once installed, wash with warm soap and water to remove the protective coating and encourage development of an even patina - this may take weeks or months depending on weather conditions.

Our products

We’re dedicated to designing strong, lasting edges that suit any garden. And developing the best possible edging solutions that are DIY-friendly and meet the requirements of high-end landscaping companies.

We offer a full range of retaining solutions for residential and commercial garden applications. Whether you want to create a single raised garden bed or a complex, multi-level garden design, our Flex & Rigid raised garden bed products will make your task much easier to complete.

For a low-maintenance, natural-looking, low garden wall that will stand firm for many years, you won’t find a better option than our steel raised garden beds in the style of Corten. The natural patina that forms on steel is very stable and lends a mature, organic appearance to any type of garden.

If you like the idea of a durable steel retaining solution but you want a more contemporary finish that will retain its original appearance over a long period of time, we recommend taking a look at our galvanised steel products.

Whether you opt for galvanised steel or weathered oxidised steel, you can choose from either curved or straight profiles, with a height of 240mm, 400mm, or 560mm. Perfect sizes and profiles for any steel raised garden beds.

Flex & Rigid Weathered Steel Raised Garden Beds

Our two main above-ground retaining solutions enable both DIY gardeners and landscaping professionals to build raised beds of any shape or size, quickly and inexpensively.

Our Flex range is designed to be curved by hand to accommodate any bends in your beds, whilst our Rigid range is for straight runs. Both products are very easy to install and can be seamlessly joined together (using our included wedge & slider system), making it easy for you to tackle all sorts of landscaping projects with ease. The even patina they develop helps them to blend in with mature gardens, creating a very natural yet orderly aesthetic that would normally cost much more to achieve.

Flex & Rigid Galvanised Steel Raised Garden Beds

Even though it is undoubtedly attractive, we understand that not everybody is looking for a retaining solution with a weathered finish. It is for this reason that we also offer our Flex & Rigid raised garden bed products in a galvanised finish, which is even more durable than weathering steel. Our galvanised steel raised garden beds are perfect for contemporary garden designs where a clean, modern aesthetic is preferred.

Low Garden Wall Solutions

Whether you are creating a feature garden that requires a low wall or you want to quickly erect a wall between a terrace and the rest of your backyard, our above-ground retaining solutions will be perfect for your requirements. With our Rigid raised garden bed panels, you can create straight runs that will require little to no maintenance while our Flex products will allow you to create a curved garden wall far more easily than any other readily available retaining solution.

Planter Boxes

We also offer freestanding planter boxes in weathered steel, in heights of 400mm and 560mm. These can be used anywhere that you would like a separate, raised planter.

Retaining & Edging Solutions for Domestic & Commercial Customers

Thanks to their low cost and ease of installation, our above-ground retaining solutions are ideal for both professionals and garden enthusiasts alike. If you want to install our weathered steel raised garden beds and other above-ground features with a minimum of fuss, these products are your best option. In addition to our above-ground solutions, we also offer in-ground edging for lawns, garden beds, and other applications.
