The best metal raised beds, compared.
Top pick: Harbour Housewares 180 cm – Highest card score, 84, from 4.7 and 246 amazon.co.uk reviews, with 486 litres that match a 180 × 90 × 30 cm bed. Best value: VIREO GARDEN round pair – Two 120 cm rounds at about £30.63, the lowest price for that footprint, on 4.6 from 54 reviews. Updated October 2026.
A metal raised bed is a kit of galvanised steel panels that bolt into an open-bottom frame for soil. On amazon.co.uk the useful checks are footprint, wall height, how many beds are in the carton, and whether the capacity line matches that box. Most of the ten kits are about 30 cm high. One listing adds a trellis, and its litre line uses the full frame height rather than the soil. There is no corrosion trial and no grow-out. Thickness, reach, and description clashes are in the [metal raised bed buying guide](/hub/raised-beds-greenhouses-and-compost/raised-bed-metal/sub/raised-bed-metal-buying-guide). You set it on soil or on a hard surface and fill it.

Personal buying guide
Question 1 of 2
Where will the bed stand?
Across 246 amazon.co.uk reviews rated 4.7, the Harbour Housewares kit builds into a rounded 180 × 90 × 30 cm open-bottom bed. The listing states 486 litres, and that figure matches 1.8 × 0.9 × 0.3 metres. Reviewers usually call the build straightforward once the panels line up, and one 79-year-old buyer with arthritic hands finished in just under an hour. The empty frame weighs 6.64 kg, so you can place it alone, then the soil is what stiffens the walls. Instructions are the recurring snag: one UK reviewer found the wing nuts fiddly and used pliers plus a driver, and another reported some wing nuts missing. Sheet thickness is not on the listing, and a 30 cm wall on paving is the entire root zone.
Pros
Cons
Best for: A first vegetable rectangle on open soil, 90 cm wide so you can reach it from both long sides.
Less suitable: A patio or tarmac plot where you need more than 30 cm of root depth, or a buyer who wants a stated steel gauge.
Specifications
Common questions
Does this kit include a base?
The listing describes an open-bottom raised bed. No solid base plate is in the bullets. On soil, roots can continue below the wall. On paving, 30 cm is the whole root zone.
What size is on the listing?
The size line is 180 × 90 × 30 cm. The stated capacity is 486 litres, which matches that box.
Is galvanised steel thickness stated?
No. This listing does not state a gauge. Do not treat a blank as a thickness.
The pack is two rounded Harbour beds at 120 × 60 × 30 cm for £39.99. The listing capacity of 0.22 cubic metres matches one bed, about 216 litres, so the pair is closer to 430 litres of mix. Across 191 amazon.co.uk reviews at 4.7 stars, buyers describe adding further beds in the same range. One timed the build at about 30 minutes a bed. Another counted 10 panels and 80 bolts with wing nuts on each bed and called that an absolute pain, even after the vegetables were growing. The panels feel light in the carton and firmer once filled, and one household put about 12 large bags of compost, plus cardboard and garden waste, into the beds. Thickness is unstated.
Pros
Cons
Best for: Two narrow vegetable zones on open soil, where you would rather have separate beds than one wide rectangle.
Less suitable: A single large plot, or a build you want finished with only a handful of fixings.

Common questions
Does this kit include a base?
The listing describes an open-bottom raised bed. No solid base plate is in the bullets.
What size is on the listing?
Each bed is 120 × 60 × 30 cm, sold as a pack of two. The stated 0.22 cubic metres is about 220 litres for one bed.
Is galvanised steel thickness stated?
No. This listing does not state a gauge.
Ergohortus supplies two oval beds of 120 × 60 × 30 cm for £38.99. The stated 216 litres matches one bed, so two full beds are about twice that. Across 105 amazon.co.uk reviews at 4.7 stars, a wheelchair user assembled a set and planted from the chair, which is one person's experience and not a measured access height. Another bed took three to four 50-litre bags of compost plus some topsoil. Adjustable plant-support poles are in the box, and reviewers tell you to wear the supplied gloves because the edges are sharp before the trim is fitted. A second set in one order had holes that did not line up and took over four hours, against about an hour and a half for the first set. Thickness is not stated.
Pros
Cons
Best for: Two narrow beds you can reach from one side, including seated gardening if a 30 cm wall is high enough for you.
Less suitable: A buyer who wants a printed steel gauge, or one single 180 cm bed.

Common questions
Does this kit include a base?
The listing describes an open-bottom raised bed. No solid base plate is in the bullets.
What size is on the listing?
The size line is two beds of 120 × 60 × 30 cm. The stated capacity is 216 litres, which matches one bed.

No. This listing does not state a gauge.
This INNO STAGE carton is three round rings of about 60 × 60 × 30 cm at £36.99. The stated 4 cubic feet is about 113 litres, which fits one ring of roughly 108 litres and leaves the other two rings out of that line. The amazon.co.uk rating is 4.6 from 267 reviews, the largest count in this comparison, though some comments describe other pack sizes in the same brand range. UK buyers report a simple build once a panel is turned so the holes meet, and one set stayed tidy through a growing season. The pack weighs 7.9 kg and reviewers say the rings feel flimsy until the soil is in. One UK review called the metal very thin, the edges sharp, and the rubber edging shown in the photos missing; another was short two butterfly nuts and bought them locally. Peeling the protective film takes longer than the bolts.
Pros
Cons
Best for: Herbs, salads, or a spare corner where a full rectangle will not fit, on open soil.
Less suitable: A main vegetable plot, or hard standing where 30 cm of wall is all the root room you get.
Specifications
Common questions
Does this kit include a base?
The listing describes an open-bottom raised bed. No solid base plate is in the bullets.
What size is on the listing?
Each ring is about 60 × 60 × 30 cm, sold as a three-pack. The stated 4 cubic feet is about 113 litres, which fits one ring.
Is galvanised steel thickness stated?
No. This listing does not state a gauge. A UK review described the sheet as very thin.
VIREO's two-pack is a pair of round 120 × 120 × 30 cm rings at £30.63. A circle of that size at 30 cm holds roughly 340 litres, and the listing's 10.7 cubic feet is about 303 litres, so the capacity line describes one ring. Across 54 amazon.co.uk reviews at 4.6 stars, UK buyers call the rings sturdy once built and say the hardware goes together without tools. Assembly is still described as a little tedious, and the listing fits a rubber strip to the top edge. Fifty-four reviews is a thinner sample than the Harbour rectangle, and thickness is not printed. A 120 cm diameter is wider than a comfortable reach from one side.
Pros
Cons
Best for: Two large round beds on open soil when the price for the footprint matters and you can walk around each ring.
Less suitable: A narrow path, one-sided reach from a wheelchair, or a patio that needs more than 30 cm of soil.

What size is on the listing?

INNO STAGE's two-pack is two runs of 240 × 60 × 30 cm for £39.99. The stated 16 cubic feet is about 453 litres, and one bed at those dimensions is 432 litres, so the line covers one run. The same listing names stainless steel in one material field and galvanised steel in the finish, so neither word is settled until you have the panels in front of you. Across 40 amazon.co.uk reviews at 4.6 stars, UK buyers found the shape easy to build. One parcel arrived with bent corners on the long panels; the buyer bent them back and set those panels along the bottom where soil would hide them. A 60 cm width is reachable from one side, the pair weighs 15.7 kg empty, and thickness is unstated on a sample of only 40 reviews.
Pros
Cons
Best for: A fence-line vegetable run on open soil, split into two narrow beds.
Less suitable: A buyer who needs one material named clearly, or a wide mixed planting in a single frame.

KING BIRD sells one 180 × 90 cm open-bottom bed with a trellis, and the overall listed height is 180 cm, at £59.99. The growing-space bullet is 180 × 90 × 30 cm, while the 2,916 litre capacity uses the full 180 cm height and will send you far too much compost. A UK reviewer allowed about nine 60-litre bags, which tracks the 30 cm soil box of about 486 litres, and noted there is no base. Across 28 amazon.co.uk reviews at 4.6 stars, buyers grow vegetables and fit the trellis with the included screwdriver. One buyer was missing parts. Another found the sheet flimsy and the edge sharp, and judged the extra money to be for the trellis. Twenty-eight reviews is a small base for a £59.99 kit.
Pros
Cons
Best for: Climbers on a single 180 × 90 cm bed on open soil, if you order compost from the 30 cm soil box.
Less suitable: A plain soil box without a frame above it, or a patio where 30 cm of soil is the whole root depth.
Specifications
Common questions
Does this kit include a base?
The listing describes an open-bottom raised bed. A UK reviewer noted there is no base. No solid base plate is in the bullets.
What size is on the listing?
The overall size line is 180 × 90 × 180 cm because it includes the trellis. The growing-space bullet is 180 × 90 × 30 cm.
Does the capacity line match soil depth?
No. The 2,916 litre line uses the full 180 cm height. Order compost from the 30 cm soil box, about 486 litres, not from the trellis height.
This HEALSTOK oval is one 180 × 90 × 30 cm bed, sold as 6 × 3 × 1 ft, at £26.55. The stated 18 cubic feet is about 510 litres and matches that footprint at a 30 cm soil depth. The empty kit weighs 7.34 kg. The amazon.co.uk line is 4.3 from 66 reviews, a weaker record than the Harbour bed of the same class. A UK reviewer liked the colour and the stated size, then found four screws missing, and the instruction to contact the seller through Amazon did not give them a working route. Other reviews on the listing mention sharp edges, film that lifts more easily once warm, and sheet that feels thin. The built oval is awkward to shift on your own before it is filled, and thickness is not stated.
Pros
Cons
Best for: A first large oval on lawn or soil, if you check the screw count before you start filling.
Less suitable: A buyer who wants the longer review history of the Harbour 180 cm bed.

ZORMY's two-pack is two rectangles listed as 8 × 2 × 1 ft, about 244 × 61 × 30 cm, at £41.99. It is the only kit in this comparison that prints a thickness, 0.4 mm galvanised steel, with a rubber top edge and gloves in the bullets. Across 14 amazon.co.uk reviews at 4.3 stars, UK buyers say the beds held their shape once filled, and one allotment pair went together without trouble. Another UK buyer found the wing nuts and screws poor enough to rule out a second order. The item-dimensions line of 42 × 32 × 8.5 cm is the parcel, so a compost calculation has to start from the 8 × 2 × 1 ft title because no litre figure is given. Fourteen reviews cannot show how 0.4 mm sheet behaves after a UK winter.
Pros
Cons
Best for: Two narrow runs where you want a printed thickness and you will measure the panels against the 8 ft title.
Less suitable: Anyone reading the item-dimensions line as the garden size, or anyone who wants a large review sample before buying 0.4 mm sheet.

Common questions

The listing describes an open-bottom raised bed. No solid base plate is in the bullets.
What size is on the listing?
The title size is 8 × 2 × 1 ft, about 244 × 61 × 30 cm, as a two-pack. The item-dimensions line of 42 × 32 × 8.5 cm is the parcel, not the bed. No litre capacity is stated.
Is galvanised steel thickness stated?
Yes. The bullets state 0.4 mm. That is the only printed gauge in this comparison. Fourteen reviews do not show how that sheet lasts a UK winter.
This HEALSTOK pair is two rectangles of about 120 × 60 × 43 cm, listed as 4 × 2 × 1.4 ft, at £52.05. The stated 319.8 litres matches one bed. A 43 cm wall is the deepest plain side in this comparison and sits near the RHS 45 cm band for deeper crops, while the RHS schools sheet still asks for at least 50 cm where the bed stands on tarmac. The amazon.co.uk rating is 4.2 from 30 reviews, the lowest star line kept here, and many comments on the page are from outside the UK. A UK buyer found the metal support struts much too short for the width. The pair weighs 14.1 kg empty and the listing does not state a thickness.
Pros
Cons
Best for: Two deeper vegetable boxes on open soil when a 30 cm wall feels too shallow for the crops you want.
Less suitable: A first low-cost bed, or a buyer who cannot return the kit if the braces do not span the width.

Decide the footprint before the stars. These ten kits are open-bottom galvanised frames, captured on amazon.co.uk on 20 October 2026, from about £26.55 to about £59.99. A timber bed, a plastic trough, and a UK-made 1 mm frame are different products. Prices can move after that date.
A metal raised bed here is a bolt-together frame of galvanised sheet with no floor. You set it on soil or on a hard surface and fill it. The ten amazon.co.uk listings kept for this page were priced on 20 October 2026 from about £26.55 to about £59.99. A wider UK shelf, only as context, includes RHS Plants galvanised frames at about £43 to £53 and Harrod Horticultural UK-made 1 mm beds from about £88. Those prices are not these ASINs, and they are a rule of thumb rather than a market study.
The KING BIRD capacity of 2,916 litres uses 180 cm overall. The soil bullet is 30 cm, about 486 litres. A UK reviewer used about nine 60-litre bags. Buy the smaller figure.
On open soil, roots can leave the frame. On paving the wall is the whole root zone. The RHS schools sheet asks for at least 50 cm there. The deepest plain wall here is 43 cm.
ZORMY’s item-dimensions line is 42 × 32 × 8.5 cm. That is the carton. The garden size in the title is 8 × 2 × 1 ft. The INNO STAGE long pair also names both stainless and galvanised. Check the panels against the description before you fill.
A single 180 × 90 cm bed, the Harbour kit at about £30.99 or the HEALSTOK oval at about £26.55, is one vegetable rectangle you can reach from both long sides. Pairs of 120 × 60 cm beds, Harbour or Ergohortus, split crops and stay narrow enough for one-sided reach. The INNO STAGE long pair is two runs of 240 × 60 cm. VIREO is two 120 cm rounds at about £30.63. The INNO STAGE three-pack is three 60 cm rings, not a main plot.
About 30 cm is the RHS band for salads and strawberries when the bed sits on soil and roots can continue downwards. The HEALSTOK pair at about 43 cm, about £52.05, is the only plain wall near the 45 cm band the RHS uses for most fruit bushes and small trees, and it is still under the 50 cm the same charity’s schools sheet wants on tarmac. A 180 cm overall height on the KING BIRD kit is the trellis. The soil bullet remains 30 cm.
Three typical situations, each with a recommendation from this comparison.
You want one vegetable rectangle on open soil, reachable from both long sides. The Harbour Housewares 180 × 90 × 30 cm bed states 486 litres, which matches that box. A 30 cm wall is the RHS band for salads and strawberries when roots can continue into the ground.
On a hard surface the wall is the whole root zone. The RHS schools sheet asks for at least 50 cm there. No kit here states 50 cm. The HEALSTOK pair at about 43 cm is the deepest plain wall, and it is still short of that figure.
Read the tenancy before delivery. Some sites ask for written consent for a raised bed, and some restrict metal that is not for cropping. Two narrow 120 × 60 cm beds are easier to site along a path than one wide ring. The Harbour twin pack is that shape, with a fiddly wing-nut build in the reviews.
These ten kits are open-bottom galvanised frames, from about £26.55 to about £59.99 on the 20 October 2026 amazon.co.uk capture. The Harbour Housewares 180 × 90 × 30 cm bed, about £30.99, is the top pick: card score 84, with 4.7 from 246 reviews and a 486 litre line that matches the box. Thickness is not stated. The VIREO pair of 120 cm rounds, about £30.63, is the best value for footprint, on a thinner sample of 54 reviews, and each ring is wide to reach across. Do not order compost from the KING BIRD 2,916 litre line. That figure uses the trellis height.
