Profile Features
20 x 40mm Standard Profile
GW2040 measures 20mm thick x 40mm wide. Compared with GW1840S, GW2040 has the same 40mm width with an additional 2mm of profile thickness. Final profile selection should also consider the complete frame size, canvas weight and stretching requirements.
Raised Canvas-Contact 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 GW2040 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.
Corner Fit for Different Assembly Methods
Corner 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 using a 20 x 40mm internal profile
- Private-label and wholesale canvas frame programs

Ordering, Lengths and Customization
Lengths and Standard Supply
GW2040 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 according to the composition and total quantity of the complete order.
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 application. For frame structures that require a profile outside the standard range, 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 the production of longer bar lengths, while kiln drying helps control 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 20 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
