Standard Wooden Stretcher Bars
Gowin’s current Standard Wooden Stretcher Bar range includes nine pine profiles with thicknesses from 16mm to 20mm and widths from 24mm to 45mm. They are supplied for B2B canvas-frame production, wholesale ranges and private-label programs, with samples available for profile and assembly confirmation.
The appropriate profile should be confirmed from the complete frame specification rather than thickness or width alone. The model table below provides a practical starting point for comparison.

Choose a Standard Wooden Stretcher Bar Profile
Gowin states all Stretcher Bar dimensions as thickness × width. For example, 18 × 40mm means 18mm thickness × 40mm width. The table below compares the nine current Standard profiles using only confirmed dimensional and profile details.
| Model | Profile: Thickness × Width | Profile Note |
|---|---|---|
| GW1624 | 16mm thickness × 24mm width | Narrowest 16mm-thick profile in the current Standard range. |
| GW1629 | 16mm thickness × 29mm width | 16mm-thick profile with 29mm width. |
| GW1635 | 16mm thickness × 35mm width | Widest of the three current 16mm-thick Standard profiles. |
| GW1838 | 18mm thickness × 38mm width | 18 × 38mm Standard profile. |
| GW1840S | 18mm thickness × 40mm width | Includes a raised outer canvas-contact lip. |
| GW1845F | 18mm thickness × 45mm width | Specific F profile shape; check the full cross-section when matching. |
| GW1935 | 19mm thickness × 35mm width | 19 × 35mm Standard profile. |
| GW2035 | 20mm thickness × 35mm width | 20 × 35mm Standard profile. |
| GW2040 | 20mm thickness × 40mm width | Raised outer canvas-contact lip; 20 × 40mm profile. |
How to Select the Profile
If you are matching an existing frame, compare the full profile shape as well as the nominal thickness and width. A profile drawing, complete cross-section dimensions or a physical sample gives a more reliable basis for confirmation.
For a new canvas-frame program, review the following together:
- Complete finished frame dimensions
- Outer Stretcher Bar profile and cross-section
- Canvas specification or weight
- Stretching tension and assembly method
- Internal support layout
- Final application and packing requirements
When to Evaluate Internal Support
As a general starting point, the need for internal support should be considered when the long side reaches approximately 60cm. This is not a mandatory threshold. The final decision depends on the complete frame dimensions, outer profile, canvas specification, stretching tension, support layout and final application. See Supporting Bars & Bespoke Stretcher Bar when the frame specification includes internal reinforcement or a profile outside the current range.
Pine Wood and Production Details
Kiln-Dried Pine and Finger-Jointed Construction
Gowin’s Standard profiles are made from kiln-dried pine and are smooth-sanded after machining. Finger-jointed construction is used where applicable, and the nine current Standard profiles can be supplied in lengths up to 300cm.
Regular pine may include slight sound knots. If your program requires a cleaner appearance or a different wood grade, confirm the requirement before sampling and quotation.
Surface, Dimensions and Corner Fit
During production, we check profile dimensions, straightness, smooth sanding, corner fit and packing condition. Corner fit can be confirmed during sampling according to your intended assembly method and frame-production requirements.
Tenoned and Non-Tenoned Options
For tenoned Standard Stretcher Bars, the four sides are normally assembled by fitting the machined corner joints together, so conventional frame nailing is generally not required for basic assembly. Additional reinforcement may still be used according to the complete frame structure and application.
Non-tenoned bars can be supplied when you have your own tenoning machinery or intend to use direct-nailing frame assembly. Confirm the required corner structure before sampling.
If you cannot visit the factory in person, you can view production and assembly footage on Gowin’s YouTube channel.

Existing and Custom Profile Options
Gowin’s existing 20 Stretcher Bar and Supporting Bar profiles cover many common market requirements, but you are not limited to the current range. If your project requires a special thickness or width, a different cross-section, or a profile matching an existing product, we can review custom development from a technical drawing with complete cross-section dimensions or a physical sample.
Custom profiles remain subject to technical feasibility, sample confirmation, MOQ or order requirements and agreed tooling conditions. A new profile may require a mould or tooling charge, which is normally refundable after the agreed formal production order is placed, subject to the agreed order conditions. More detailed requirements can be discussed through Supporting Bars & Bespoke Stretcher Bar.
For sample and quotation preparation, provide the required frame sizes, bar lengths and quantity by size, canvas specification, tenoned or non-tenoned requirement, assembly method, any known internal-support requirement, packing requirements and destination.
Frequently Asked Questions
What do Standard Stretcher Bar dimensions mean?
Gowin lists dimensions as thickness × width. A profile listed as 18 × 40mm therefore has an 18mm thickness and a 40mm width.
Are tenoned and non-tenoned Standard Stretcher Bars available?
Yes. Tenoned bars are available for fitted-corner assembly. Non-tenoned bars can be supplied when you have your own tenoning machinery or use a direct-nailing frame process.
What lengths and MOQ are available?
The nine current Standard profiles list lengths up to 300cm. The normal MOQ is 1,000 pieces per size, while a lower quantity may be discussed according to the complete order.
Can Gowin review an existing Stretcher Bar profile?
Yes. Provide a profile drawing, complete cross-section dimensions or a physical sample together with the required lengths and quantities. Feasibility, sampling and MOQ can then be confirmed.
Can regular pine contain knots?
Regular pine may include slight sound knots. Confirm any cleaner appearance or different wood-grade requirement before sampling and quotation.
