GW1845F – 18 x 45mm Standard Wooden Stretcher Bar
GW1845F is an 18 x 45mm pine wooden Stretcher Bar in Gowin’s Standard Wooden Stretcher Bars range. Gowin states Stretcher Bar dimensions as thickness x width, so this profile has an 18mm thickness and a 45mm width. It is an outer frame component used to form the perimeter over which the canvas is stretched.
GW1845F can be supplied in tenoned or non-tenoned structures, with lengths up to 300cm. Before ordering, confirm the finished frame sizes, required bar lengths, canvas specification, assembly method and packing requirements so the complete frame specification can be reviewed together.

Product Features
18mm Thickness x 45mm Width
The GW1845F profile measures 18mm in thickness and 45mm in width. Both dimensions should be checked together with the required profile shape, finished frame dimensions, canvas specification, stretching tension, internal support requirement and final application.
GW1845F Profile Shape
The model suffix identifies the GW1845F profile. When you need to match an existing canvas-frame program, nominal dimensions should be checked together with the complete cross-section shape.
Tenoned and Non-Tenoned Options
For standard tenoned bars, the four frame 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 depending on 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 structure before sampling and quotation.
Assembly Fit Confirmation
Corner fit can be confirmed during sampling according to your intended assembly method and frame-production requirements.
Recommended Applications
- Stretched canvas production
- Printed canvas and photo canvas frames
- Decorative wall art
- Standard-profile canvas-frame programs
- Wholesale and private-label canvas-frame production
How to Evaluate the 18 x 45mm Profile
Profile selection should begin with the complete finished frame specification. Review the finished frame dimensions, 18mm profile thickness, 45mm profile width, required profile shape, canvas material, stretching tension, internal support plan, assembly method and final application before confirming GW1845F.
If you are developing a new frame program, test the profile with the intended canvas and frame dimensions. If you are matching an existing product, provide a cross-section drawing or physical sample so the profile shape can be checked as well as the nominal dimensions.
GW1845F and GW1840S Profile Comparison
GW1845F and GW1840S are both Standard Wooden Stretcher Bars with an 18mm thickness. GW1845F has a 45mm width, while GW1840S has a 40mm width. The 5mm width difference should be reviewed together with the required cross-section and complete frame specification.
| Model | Profile | Product Family | Key Difference |
|---|---|---|---|
| GW1845F | 18 x 45mm | Standard profile | 18mm thickness with 45mm width |
| GW1840S | 18 x 40mm | Standard profile | Same 18mm thickness and 5mm narrower than GW1845F |
Internal Support Guidance
GW1845F forms the outer perimeter of the frame. Internal Supporting Bars are separate components that may be added according to the complete frame structure.
As a general starting point, internal support should normally be considered when the long side reaches approximately 60cm. This is general guidance rather than a fixed engineering rule, and it does not mean that every frame at this size requires a Supporting Bar.
The actual requirement depends on the finished frame dimensions, outer profile, canvas specification, stretching tension, support layout and final application. If you already use a particular support profile or frame drawing, include it for confirmation before production.
Ordering, Lengths and Customization
Lengths and Order Quantities
GW1845F can be supplied in lengths up to 300cm. For quotation, provide the required length list and quantity for each size. 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.
Profile and Assembly Requirements
Please confirm the required GW1845F profile shape and whether you need tenoned bars for fitted-corner assembly or non-tenoned bars for your own machining or direct-nailing process. Assembly fit, packing and labeling requirements can be confirmed according to the order.
If you are matching an existing Stretcher Bar, provide a profile drawing, complete cross-section dimensions or a physical sample where available. Include the finished frame sizes, canvas specification and estimated quantities so feasibility, sampling and MOQ can be confirmed.
Wood, Production and Quality
GW1845F follows the general pine-wood and production basis used for Gowin’s wooden Stretcher Bars. The wood is kiln-dried before machining, and finger-jointed construction is used where applicable.
During production, we check profile dimensions, profile shape, straightness, surface sanding, joint fit and packing condition. Regular pine may include slight sound knots. If a cleaner appearance or different wood-grade requirement is needed, confirm it before sampling and quotation.
Packing and Export Supply
OEM and private-label packing are available. Packing and labeling requirements can be confirmed according to the bar lengths, quantities, corner structure and shipping method.
For full-container orders, FOB terms can be discussed; otherwise, supply is normally based on EXW terms. DDP or door-to-door delivery can also be discussed according to the destination and order requirements.
Sample and Profile Confirmation
Samples are available. Before bulk production, confirm the 18 x 45mm dimensions and GW1845F profile shape together with the intended canvas, frame size and assembly method.
For sample and quotation preparation, please provide:
- Finished frame sizes
- Required bar lengths and quantities by size
- Profile drawing, cross-section dimensions or physical sample, if available
- Canvas specification and stretching method
- Tenoned or non-tenoned structure
- Internal support requirement, if already known
- Packing requirements and destination
Frequently Asked Questions
What do the GW1845F dimensions mean?
GW1845F measures 18 x 45mm. Following Gowin’s thickness x width convention, this means 18mm thickness and 45mm width.
Is GW1845F an outer Stretcher Bar?
Yes. GW1845F is a Standard outer wooden Stretcher Bar used to form the perimeter of a canvas frame. It is not an internal Supporting Bar or Cross Brace.
How does GW1845F differ from GW1840S?
Both models have an 18mm thickness. GW1845F has a 45mm width, while GW1840S has a 40mm width. Confirm the required model from the complete profile and frame specification.
When should internal support be considered?
As a general starting point, internal support should normally be considered when the long side reaches approximately 60cm. This is not a fixed rule; the final requirement depends on the complete frame dimensions and structure.
