GW1840S is one of Gowin’s established and best-selling standard wooden stretcher bar profiles. Made from pine wood, it measures 18mm thick x 40mm wide and is supplied for repeat production of stretched canvas, printed canvas frames and private-label canvas products.
GW1840S can be supplied in tenoned or non-tenoned structures, with lengths up to 300cm. It sits within Gowin’s standard wooden stretcher bar range and is intended for regular canvas-frame production where neither greater frame depth nor a Heavy Duty structure is required.

Profile Features
18 x 40mm Standard Profile
The 18mm thickness and 40mm width place GW1840S within Gowin’s standard profile range. The dimensions should be evaluated together with the finished frame size, canvas tension and whether internal support is required.
Raised Canvas Lip
The profile includes a raised outer lip that provides clearance between the stretched canvas and the main face of the wooden bar.
Tenoned and Non-Tenoned Options
For standard tenoned GW1840S bars, the four bars 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 depending on frame size, profile design and application.
Non-tenoned structures can be supplied when you have your own tenoning machinery or plan to assemble the frame directly with nails. Pre-assembled frames may also be secured with staples according to the assembly and packing method.
Adjustable Corner Fit
Assembly fit can be discussed during sampling. Some production teams prefer a tighter joint for light hammer-assisted assembly, while DIY programs may require an easier fit for assembly by hand.
Recommended Frame Production Uses
- Standard stretched canvas production
- Blank artist canvas manufacturing
- Printed canvas and photo canvas framing
- Framed wall decor with a standard-depth internal frame
- Private-label and wholesale canvas frame programs

| Model | Profile Dimensions | Category | Relative Profile Size | Key Difference |
|---|---|---|---|---|
| GW1935 | 19 x 35mm | Standard profile | 1mm thicker and 5mm narrower | Narrower width than GW1840S |
| GW1840S | 18 x 40mm | Standard profile | Reference profile | 40mm width with an 18mm thickness |
| GW1845F | 18 x 45mm | Standard profile | Same thickness and 5mm wider | Wider profile at the same 18mm thickness |
| GW2040 | 20 x 40mm | Standard profile | 2mm thicker with the same width | Thicker profile at the same 40mm width |
These dimensional differences help narrow the profile choice, but the final decision should also consider frame size, canvas tension, assembly method and packing. The complete wooden stretcher bar range includes standard, deep profile, heavy duty and supporting structures.
Ordering, Lengths and Customization
Lengths and Standard Supply
GW1840S can be supplied in cut lengths up to 300cm. Please provide the required length list and quantity for each size when requesting a quotation. The standard MOQ is 1,000 pcs per size, although a lower quantity may be discussed when the complete order includes multiple sizes or profiles.
Frame Size and Supporting Bars
From about a 60cm long side, the need for a supporting bar should be evaluated according to the complete frame dimensions, canvas weight, stretching tension and final use. For larger formats where the 18mm profile is not appropriate, compare Gowin’s heavy duty stretcher bars.
Bespoke Profile Requirements
If your project requires a different thickness, width, corner structure or assembly fit, provide a drawing or physical sample. Feasibility, sampling and MOQ can then be confirmed for the requested profile.
Wood, Production and Quality Information
Gowin uses pine wood because its supply is stable and longer lengths are available for stretcher bar production. Finger-jointed construction allows selected pine sections to be joined for longer bar lengths, while kiln drying removes excess moisture before machining.
During production, we check profile dimensions, surface sanding, joint fit, moisture control and packing condition. Regular pine supply may include slight sound knots. If a cleaner appearance or stricter wood grade is required, please specify this before sampling and quotation, as it may affect material selection and pricing.
Packing and Export Supply
OEM and private-label packing are available. Packing and labeling requirements can be confirmed according to the ordered lengths, corner structure, quantities and shipping method.
FOB and EXW terms are available according to the order volume and shipment arrangement. For customers who prefer a more complete delivery solution, DDP or door-to-door delivery can also be discussed according to the destination and order requirements.
Sample and Profile Confirmation
Samples are available to confirm the 18 x 40mm profile, raised lip, surface, corner fit and assembly method before bulk production. Please provide:
- Required frame sizes and bar lengths
- Canvas type and expected stretching method
- Tenoned or non-tenoned structure
- Preferred corner fit and assembly method
- Estimated quantity, packing requirements and destination
Frequently Asked Questions
