Precision engineered planter boxes that are designed to last

With little to no fuss, simply fix panels together and place in your garden for a professionally finished look. 

If you love high-end aesthetics... 

One reason to love our planter boxes is that they look very stylish – we’ve intentionally designed them to enhance the look & feel of the gardens they feature in. Our planters look so good because they’re:

  • Made from real weathering steel for a rustic natural look that develops with a rusted patina.
  • Internally joined with concealed fittings to produce clean lines and beautiful seam details.
  • Precision-engineered to achieve a stylish, high-end aesthetic with every installation.
  • Designed with a 45mm top edge to form a stylish, boxy profile. 

If you value high-quality... 

Simply put, you won’t find a better quality steel planter, because Straightcurve planter boxes are:

  • Very high-quality landscaping products made to exacting standards.
  • Designed & manufactured to an exceptionally high standard for a flawless fit & finish.
  • Made from 2mm thick high-quality engineered weathering steel panels. 

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

Our planter boxes 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 + bracing systems.
  • Quality tested to ensure landscape industry-leading durability. 

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 planters are ideal for you because they’re:

  • Designed to fit neatly together via a hidden joining system that produces a beautiful seam detail at the joins.
  • Engineered to stay strong & true for many years after installation – the thickness of the steel and the way the system is designed to hold together means our planters won’t budge, bulge, crack or otherwise change shape once installed. 

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

Our planters 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.
  • Supplied with an integrated stabilising foot for installation on level ground (which means there’s no need to bury any part of the edge, so you’re not paying for material you’ll never see).
  • Maintenance-free once installed and weathered.

 

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

 

Our planters are easy to build. 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 planters 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

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.
