Why You'll Love It
An extra-deep, flexible garden bed designed to give you more growing space.
Build One 320cm Bed or Two 160cm Beds
The versatile 2-in-1 configuration lets you assemble the panels as one extra-long 320cm x 80cm x 77cm garden bed, or divide them into two 160cm x 80cm x 77cm beds.
Create one substantial vegetable garden or position the two beds separately to make the best use of your available backyard space.
Extra Depth for a Wider Variety of Plants
At 77cm high, this substantial raised garden bed provides generous depth for layered filling and healthy root development. The extra height also brings your garden closer to you, reducing how far you need to reach down while planting, watering, weeding or harvesting.
Grow leafy greens, herbs, strawberries and flowers, as well as larger crops such as tomatoes, carrots and other deeper-rooted vegetables.
0.3mm Galvanised SGCC Steel
The garden bed is made from 0.3mm galvanised SGCC steel with an epoxy powder-coated finish designed for outdoor use.
The profiled steel panels and three supplied internal support braces help the long sides maintain their shape when the garden bed is correctly assembled and filled.
Grow Your Garden Your Way
Fill your garden bed with a mix of vegetables, herbs, flowers and seasonal plants, or use the two-bed configuration to create separate growing areas for different crops.
Position the bed along a fence, beside a pathway, in a sunny backyard corner or as part of a larger kitchen garden.
Garden Co Tip: At 77cm high, you don’t need to fill the entire garden bed with premium growing soil. A layered filling method can reduce the amount of expensive soil required while still providing a quality growing layer near the top.
For the best long-term performance, assemble the garden bed using all supplied supports and fill it evenly in layers. Following our printable “How to Fill a Garden Bed” guide helps distribute pressure evenly and maintain the bed’s shape and integrity over time. You’ll find the guide further down this page.

Supports healthier roots and natural drainage
The open-bottom design allows excess water to drain freely into the ground, helping reduce waterlogging while encouraging roots to grow deeper into the soil below. Water and nutrients move through the garden bed and circulate around the root zone, creating a well-aerated growing environment for vegetables, herbs and flowers. This natural connection with the ground can support stronger root development and healthier plant growth over time.
Helps nutrients move through the soil
As water travels through the garden bed, it carries naturally occurring nutrients through the soil and around the plant roots. The roots absorb what they need to support healthy growth, while excess water continues draining through the open base rather than collecting inside the bed. This ongoing movement of water, nutrients and organic matter helps create an active growing environment for vegetables, herbs and flowers.
SGCC Galvanised Steel and Epoxy Coating
Epoxy-coated SGCC steel combines the corrosion protection of galvanised steel with an additional protective outer coating. Beneath the epoxy finish, the zinc-coated steel helps guard against rust, while the epoxy layer provides an extra barrier against moisture, everyday wear and surface damage. The coating also creates a smooth, coloured finish that gives the product a more refined appearance. Together, the two layers provide added protection for products designed for outdoor use.
