Bent Wood Arch Components: Custom Curved Wood
Curved arch components for furniture and lighting in ash, beech, walnut and zebrawood, press-curved or steam-bent to your drawing. We hold radius ratios from 1:2 (limit) through 1:5 (typical) to 1:10 (flexible).
We manufacture bent wood arch components to your drawings for furniture and interior programmes — curved arches in solid steam-bent or laminated construction. See our ash arch components and black walnut arch components for representative builds.
Arch components we manufacture
- Furniture arches — headboards, chair back arches, mirror and frame surrounds.
- Interior arches — opening trim, display architecture and decorative panelling.
- Custom curved elements — any radius, span and section your project specifies.

Why bend an arch?
An arch cut from solid stock wastes most of the board and leaves short grain at the shoulders — the exact point where the curve is tightest. A steam-bent arch follows the grain around the radius, uses less material, and is stronger at the shoulder than any cut-and-jointed alternative.
Arch engineering: why bending beats cutting
An arch cut from solid stock wastes most of the board and leaves short grain at the shoulders — the exact points where the curve is tightest and the load is highest. Under load, short grain at the shoulder is where the part breaks. A steam-bent arch follows the grain around the radius, uses less material, and puts continuous grain where the stress is.
The practical limit is the ratio of thickness to radius. As a working rule from bending practice: with a compression strap and straight-grained ash or oak, ratios down to about 1:2 are achievable; 1:5 is the recommended maximum for production reliability; and 1:10 is typical for commercial work, because no timber is perfectly straight-grained. Below those limits the answer is usually lamination, where thin veneers reach compound curves that solid wood cannot.
Radius, span and section
Three numbers define an arch, and they trade off against each other:
- Radius — set by the opening or the design; drives the minimum section for a given species.
- Span — how far the arch reaches; larger spans need either thicker sections or laminated construction to hold the line.
- Section — thicker sections need larger radii; the species decides how much larger.
Send the three numbers and we will confirm feasibility and recommend the construction — solid bent, laminated, or a hybrid with laminated springers and solid straight sections.
A note on the tradition
Bent wood is not a new idea. Michael Thonet patented his lamination process in 1841 and spent the following two decades refining it, moving from glued veneer bundles to steam-bent solid wood with a steel strap — the construction behind the No. 14 chair, six bent beech parts held by ten screws. The Vitra Design Museum’s collection holds his Boppard chair from that period as an early example of the technique. The physics has not changed; what has changed is the precision: CNC machining after bending holds finished dimensions to ±0.5 mm, which is what makes bent arches practical for production furniture rather than one-off pieces.
Applications
- Furniture — headboards, chair back arches, mirror and frame surrounds.
- Interiors — opening trim, display architecture, decorative panelling.
- Hospitality and retail — bar and counter fronts, feature walls, wayfinding elements.
Construction options for arches
| Construction | Strengths | Use when |
| Solid steam-bent | Continuous grain; strongest at the shoulder; less material | Generous radii; visible solid wood; slender sections |
| Laminated | Reaches compound curves; 1–3% springback; excellent stability | Tight radii; large spans; volume consistency |
| Hybrid | Laminated springers with solid straight sections | Large openings where the tightest curve is localised |
| Face-veneered | Premium species over a stable core | Walnut or oak appearance with forgiving behaviour |
Finishes and delivery
Arches are supplied raw for your own machining, or sanded and finished to your specification. Because arches are often installed as sightlines in interiors, surface preparation and edge treatment are confirmed on the approved sample before production. Large arches are crated to support the curve along their full length — an arch that arrives with a kinked curve cannot be straightened on site. Every shipment carries inspection reports and the standard warranty against warping and cracking in transit and use.
Ordering
Send the radius, span, section and species, plus the application and any finish requirement. We confirm feasibility — including whether the radius needs lamination — quote within 24 hours, and deliver prototypes in 7–15 days. For interior programmes, we can supply installation drawings showing fixing points machined to your spec.
Interior and architectural applications
Beyond furniture, bent arches are used wherever an opening or a sightline needs a curved timber element:
- Doorway and opening trim — arch heads in solid wood, machined to your trim profile.
- Display and retail architecture — feature arches, portal frames and merchandising structures.
- Hospitality fit-outs — bar and counter fronts, ceiling details, wayfinding elements.
- Decorative panelling — arched panels for walls and feature joinery.
For installed work we machine fixing points to your specification and supply installation drawings showing the fixing detail. Species and finish are confirmed against the environment the arch will live in — for humid or high-traffic interiors we will recommend a species and finish combination that holds its dimension.
Working with us
Send radius, span, section and species, plus the application and finish requirement. We confirm feasibility — including whether the radius needs lamination rather than solid bending — quote within 24 hours, and deliver prototypes in 7–15 days. Large arches are crated to support the full length of the curve in transit.
Summary
Bent arches put continuous grain where the stress is — at the shoulders — instead of the short grain a cut arch leaves there. The practical limit is the thickness-to-radius ratio: around 1:5 recommended for production reliability, 1:10 typical, and tighter only with straight-grained ash or oak and a compression strap; beyond that, lamination. Send radius, span and section and we will confirm which construction your arch needs.
Frequently asked questions
What are bent wood arch components used for?
Arches are used in furniture — headboards, chair backs, mirror and frame surrounds — and in interiors: doorway and opening trim, display architecture and decorative panelling.
Can you make arches to our drawing?
Yes. Send the radius, section and span you need and we will confirm the species and construction that suit it.
What is the largest span you can produce?
Span depends on species, section and radius. Our presses handle substantial lengths, and we will confirm feasibility for your specific dimension before quoting.
Do you supply arches for interior fit-out projects?
Yes — we supply interior and architectural curved elements as well as furniture components, with finishes specified to the project.
