GW3860 is a 38 x 60mm pine wooden stretcher bar in Gowin’s Heavy Duty Stretcher Bars range. The profile combines a 38mm frame depth with a substantially wider 60mm section for canvas-frame production that requires a more substantial outer structure than a standard or deep profile alone.
For comparison, GW3835G has the same listed 38mm depth but a narrower 35mm width and belongs to the Deep Profile range. GW5535 follows a different Heavy Duty direction with a 55 x 35mm profile. Your final selection should consider the complete frame dimensions, canvas weight, stretching tension, supporting structure and finished application.
GW3860 can be supplied in tenoned or non-tenoned structures, with lengths up to 300cm. Please provide your required cut lengths, frame sizes, assembly method and quantities so the profile and order details can be confirmed before production.

Profile Features
38 x 60mm Heavy Duty Profile
GW3860 measures 38mm deep x 60mm wide. The 60mm width is the main dimensional distinction between GW3860 and a 38 x 35mm deep profile. This wider section gives you a Heavy Duty profile direction for frames where the outer structure needs to be considered together with canvas tension and internal support.
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 the tenoned version, 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 according to the frame size, assembly method and application.
Non-tenoned structures can be supplied when you have your own tenoning machinery or use direct-nailing assembly. Pre-assembled frames may also be secured with staples according to the assembly and packing method.
Corner Fit Confirmation
Corner fit can be discussed during sampling. Some production teams prefer a tighter joint for light hammer-assisted assembly, while other programs require an easier fit for assembly by hand.
Recommended Frame Production Uses
- Larger stretched canvas frame production
- Decorative canvas frames requiring a 38 x 60mm wooden profile
- Printed canvas and photo canvas framing
- Wall decor manufacturing and commercial interior projects
- Wholesale and private-label canvas-frame programs
Compare Nearby Gowin Stretcher Bar Profiles
| Model | Profile Dimensions | Product Family | Dimensional Difference from GW3860 | Key Difference |
|---|---|---|---|---|
| GW3835G | 38 x 35mm | Deep profile | Same depth and 25mm narrower | Greater frame depth in a narrower 35mm profile |
| GW3860 | 38 x 60mm | Heavy duty profile | Reference profile | 38mm depth combined with a wider 60mm section |
| GW5535 | 55 x 35mm | Heavy duty profile | 17mm deeper and 25mm narrower | Greater depth with a narrower 35mm width |
GW3835G provides the same listed 38mm depth in a narrower Deep Profile structure, while GW3860 and GW5535 represent two different Heavy Duty profile directions. Final selection should be based on the complete frame dimensions and structure rather than thickness alone. The broader wooden stretcher bar range includes standard, deep profile, heavy duty and supporting profiles.
Ordering, Lengths and Customization
Cut Lengths and Order Quantity
GW3860 can be supplied in cut lengths up to 300cm. Please provide the required cut-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.
Corner Structure and Assembly Requirements
Please confirm whether you require tenoned bars for fitted-corner assembly, non-tenoned lengths for your own machining or direct-nailing process, or pre-assembled frames. Assembly fit and any additional reinforcement can be reviewed during sampling.
Bespoke Profile Requirements
If your project requires a different thickness, width, edge profile, corner structure or assembly fit, provide a profile drawing or physical sample together with the required lengths and estimated quantities. Feasibility, sampling and MOQ can then be confirmed.
Supporting Bars and Frame Structure
A Heavy Duty outer profile does not automatically remove the need for internal support. Gowin normally begins evaluating supporting bars from approximately a 60cm long side. The final requirement depends on the complete frame dimensions, canvas weight, stretching tension, outer profile and final application.
The number and layout of supporting bars should be confirmed according to the complete frame structure. Review Gowin’s supporting bar options and share the intended frame sizes during sampling.
Wood, Production and Quality Information
GW3860 is made from pine wood. Gowin uses pine 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 production, while kiln drying helps control moisture before machining.
During production, we check profile dimensions, straightness, 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 bar lengths, profile dimensions, corner structure, quantities and shipping method.
FOB and EXW terms are available according to the order volume and shipment arrangement. 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 38 x 60mm profile, raised lip, wood surface, corner fit and assembly method before bulk production. Please provide:
- Required frame sizes and bar lengths
- Canvas type and expected stretching method
- Tenoned, non-tenoned or pre-assembled structure
- Preferred corner fit and assembly method
- Proposed supporting structure
- Estimated quantity, packing requirements and destination
Frequently Asked Questions
What are the GW3860 profile dimensions?
GW3860 measures 38mm deep x 60mm wide, equivalent to 3.8 x 6.0cm.
Why is GW3860 classified as Heavy Duty?
GW3860 combines a 38mm frame depth with a substantially wider 60mm profile. This distinguishes it from narrower deep profiles such as the 38 x 35mm GW3835G.
Can GW3860 be assembled without nails?
The tenoned version is normally assembled by fitting the machined corner joints together, so conventional frame nailing is generally not required for basic assembly. Non-tenoned bars are also available for your own tenoning or direct-nailing process.
Does GW3860 still need supporting bars?
The need for internal support depends on the complete frame dimensions, canvas weight, stretching tension and final application. Gowin normally begins evaluating supporting bars from approximately a 60cm long side.
What is the MOQ for GW3860?
The standard MOQ is 1,000 pcs per size. A lower quantity may be discussed depending on the composition and total quantity of the complete order.
