GWD3828-G is a 38 x 28mm pine wooden Supporting Bar for Gowin’s GW3835G Deep Profile Stretcher Bar system. It is positioned inside the outer frame when the completed structure requires internal support. It is not an outer Stretcher Bar and is not automatically required for every GW3835G frame.
GW3835G can be configured with different Supporting Bar profiles. GWD3828-G is one confirmed option, while GWD1635-G provides a separate 16 x 35mm option. The appropriate profile should be confirmed according to the complete frame dimensions, internal support layout and required frame structure.

Supporting Bar Features
38 x 28mm Internal Profile
GWD3828-G measures 38mm by 28mm across its profile. It functions as an internal wooden component within the GW3835G perimeter frame when reinforcement is included in the confirmed frame configuration.
Specified as Part of the Complete Frame
The required Supporting Bar dimensions, connection and assembly details should be confirmed according to the complete frame structure. Reviewing the outer bars, finished frame dimensions and internal layout together provides a clear reference for sampling and production.
Designed for the GW3835G Deep Profile Frame System
GW3835G is the 38 x 35mm Deep Profile outer Stretcher Bar in this system. GWD3828-G is fitted within that perimeter when internal support is required by the completed frame specification.
Some GW3835G frames may not need a Supporting Bar, while others may require one or several. Finished frame width and height, proportions, canvas specification, stretching tension, planned support layout and final application should all be considered before the configuration is confirmed.
Supporting Bar Options for GW3835G
| Product | Profile | Application |
|---|---|---|
| GWD1635-G | 16 x 35mm | Supporting Bar option for GW3835G |
| GWD3828-G | 38 x 28mm | Supporting Bar option for GW3835G |
Both profiles are Supporting Bar options within the GW3835G frame system. The appropriate Supporting Bar profile can be confirmed according to the complete frame dimensions, internal support layout and required frame structure.
Selecting a profile is separate from deciding how many Supporting Bars the frame needs or how they should be arranged. The two available profiles do not mean that one frame must use one of each.
How Supporting Bars Work in a GW3835G Frame
The GW3835G outer bars create the perimeter over which the canvas is stretched. A Supporting Bar occupies the internal area of the frame and reinforces the required span according to the selected layout. GWD3828-G remains an internal functional component and should not replace the outer profile.
Supporting Bar dimensions, connection and assembly details should be confirmed according to the complete frame structure.
Supporting Bar Quantity and Layout
The complete GW3835G frame may use no Supporting Bar, one Supporting Bar or multiple Supporting Bars. Quantity and layout should be evaluated independently from the profile choice.
- No Supporting Bar: possible when the completed frame does not require internal reinforcement.
- One Supporting Bar: a single internal support across the required span.
- Parallel Supporting Bars: two or more internal supports running in the same direction.
- Three or more Supporting Bars: multiple supports positioned according to the full frame structure.
- Cross-brace arrangement: Supporting Bars arranged in crossing directions.
As a general starting point, internal support should normally be considered when the long side reaches approximately 60cm. This is practical guidance rather than a fixed engineering rule, and it does not mean that every frame at this size requires exactly one Supporting Bar.
How to Select the Supporting Bar Configuration
| Decision | What to Confirm |
|---|---|
| A. Supporting Bar profile | Confirm whether the 38 x 28mm GWD3828-G or 16 x 35mm GWD1635-G matches the required GW3835G frame structure. |
| B. Quantity and layout | Confirm whether the frame needs no support, one support, parallel supports, three or more supports, or a cross-brace arrangement. |
For both decisions, provide the finished frame dimensions, GW3835G outer profile, canvas specification, stretching requirements, intended support arrangement and final application. A frame drawing or established layout can also be included with your inquiry.
Ordering and Frame Configuration
To prepare the configuration and quotation, please provide:
- Finished frame sizes
- Quantity of each frame size
- GW3835G outer Stretcher Bar requirement
- Preferred Supporting Bar profile, if already specified
- Supporting Bar quantity and layout, if already specified
- Canvas specification and stretching requirements
- Packing requirements and destination
Supporting Bars are normally specified together with the complete Stretcher Bar or canvas-frame requirement. The required quantity follows the frame sizes, frame quantities and selected internal support configuration.
Wood, Production and Quality
GWD3828-G follows the same 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, straightness, surface sanding and the details confirmed for the order. Regular pine may show slight sound knots unless a different wood-grade requirement is agreed before production.
Packing and Export Supply
Export packing can be arranged according to the Supporting Bar dimensions, complete frame order and transport method. OEM and private-label packing are available, with packing and labeling requirements confirmed according to the order.
EXW is available. FOB can be discussed according to the order and shipment arrangement, while DDP or door-to-door delivery can be discussed according to the destination and order conditions.
Sample and Frame Confirmation
Samples are available. Where practical, GWD3828-G can be confirmed together with the intended GW3835G outer bars and actual canvas so that the complete frame structure and Supporting Bar configuration can be evaluated before bulk production.
Frequently Asked Questions
Is GWD3828-G an outer Stretcher Bar?
No. GWD3828-G is an internal Supporting Bar for the GW3835G frame system. GW3835G is the 38 x 35mm Deep Profile outer Stretcher Bar.
What are the GWD3828-G profile dimensions?
GWD3828-G measures 38 x 28mm, equivalent to 3.8 x 2.8cm.
What is the other Supporting Bar option for GW3835G?
GWD1635-G is the other confirmed option and has a 16 x 35mm profile. The appropriate profile can be confirmed according to the complete frame dimensions, internal support layout and required frame structure.
How many Supporting Bars does a GW3835G frame need?
The quantity depends on the complete frame. It may need no Supporting Bar, one support, parallel supports, three or more supports, or a cross-brace arrangement. Approximately 60cm on the long side is a general starting point for evaluation rather than a fixed rule.
Can GWD3828-G be tested with the complete frame?
Yes. Samples are available, and confirming the Supporting Bar together with the intended GW3835G outer bars and actual canvas is recommended before bulk production.
