Choosing a metal garden arch or rose arch
A garden arch can mark an entrance, carry a climbing rose or divide two parts of a garden. Decide whether you need to walk through it. Flat arch trellises provide support within a border, while deeper frames form an opening over a path.
Our range includes Ascalon and Garden Trading designs. Shape, finish and fixing methods vary between models. Compare the individual specifications rather than assuming every metal arch carries the same plant load. Browse metal garden ornaments for pieces to place alongside it.

Measurements below are overall product dimensions, not guaranteed clear openings. Plant growth and ground insertion reduce the space available.

Choose the right Barrington design
The rose arch creates an entrance; the arch trellis fills a narrow strip of border. Their similar names hide a useful difference. Check the product photograph and all three dimensions before choosing.
Width, planting and fixing
Measure the widest thing that needs to pass through, such as your mower or wheelbarrow. Allow room for hands and for growth on both sides. If access width matters, ask for the clear opening measurement rather than relying on the overall width.
Climbing roses need their stems tying to the support. Use suitable plant ties and check them as stems thicken. Put the support in place before the plant becomes difficult to handle. The RHS guide to tying in climbers explains the process.
Follow the manufacturer's fixing instructions for your model and ground conditions. Some designs have feet that push into soil; others need a different fixing arrangement. Before choosing for paving, confirm that suitable base fixings are available and that the supporting surface is sound. Ask for advice on exposed positions or vigorous, heavy climbers.
Finishes and other arch styles
Raw metal and a painted rust-effect finish need different care. Garden Trading's Barrington range is designed to rust outdoors. Do not assume every rust-coloured arch is corten steel or that corrosion stops once the colour develops. Follow the care instructions for the finish you buy.
For a longer planted walkway, compare the Parisienne tunnel and Bronze Gothic tunnel. Gated designs include the Woodland arch. Allow room for the gate leaves to swing.
For seating, browse metal gazebos. An entrance can also sit beside stone garden statues. Our guides cover wood and metal arches, ornamental gates and small garden layouts.
Frequently asked questions
Which garden arch should I choose for climbing roses?
Choose an arch with suitable fixing points and enough room for mature growth. Compare its clear opening, depth and the support requirements of your rose variety.
Is an arch trellis the same as a garden arch?
No, a flat arch trellis is a plant-support panel. The Barrington arch trellis is 2cm deep, while its rose arch is 40cm deep.
Do all metal garden arches need concrete?
No, fixing methods depend on the design and ground conditions. Follow the manufacturer's instructions instead of applying one foundation depth to every arch.
Can I fit a metal garden arch on paving?
Only choose a model with a suitable fixing method for that surface. Confirm the fixings and base requirements before ordering.
Will any garden arch support wisteria?
No, check the arch's suitability for vigorous, heavy climbers first. Mature growth and wind exposure affect the support required.
Will a rusted garden arch need maintenance?
Follow the care instructions for its specific material and finish. Raw metal, painted rust effects and corten steel are different products.
