Economy 38 × 28 mm Pine Canvas Stretcher Bars with Knots – CR3828

Economy 38 × 28 mm Pine Canvas Stretcher Bars

The CR3828 Economy Pine Canvas Stretcher Bar is designed for commercial canvas printing, wall art manufacturing and volume stretched canvas production where frame appearance, stability, production efficiency and cost all need to be considered.

The profile combines a 38 mm gallery depth with an economical 28 mm width, providing the deep side appearance commonly used for gallery wrap canvas while reducing unnecessary timber consumption compared with wider wooden profiles.

For customers focused on production cost, CR3828 can be manufactured using carefully selected pine containing small, tight and sound knots. This provides a more economical alternative to premium knot-free pine while maintaining the wood selection, machining and assembly standards required for commercial canvas frame production.

For customers requiring a cleaner and more uniform timber appearance, premium knot-free pine is also available.

Why Choose a 38 × 28 mm Economy Profile?

For high-volume canvas printing and wall art production, the wooden stretcher frame has a direct influence on timber consumption, finished frame weight, packing efficiency and overall production cost.

The CR3828 profile maintains a 38 mm gallery depth while using an economical 28 mm profile width. This design provides the visual depth required for gallery wrap canvas without using an unnecessarily wide wooden profile.

For commercial canvas manufacturers, the 38 × 28 mm design provides a practical balance between:

• Professional gallery-wrap appearance
• Efficient timber usage
• Frame stability
• Lower frame weight
• Efficient packing and transportation
• Competitive production cost

Economy Pine with Knots vs. Knot-Free Pine

The economical advantage of CR3828 is not only created by its efficient 38 × 28 mm profile. Wood grade is another important factor affecting the cost of wooden canvas stretcher bars.

For commercial canvas printing and high-volume wall art production, the wooden stretcher frame is normally covered by stretched canvas. In many of these applications, completely knot-free timber may not always be necessary.

Our economy option can therefore be manufactured from carefully selected pine containing small, tight and sound knots. Allowing acceptable natural knots helps reduce timber selection cost compared with premium knot-free pine while still maintaining the requirements needed for professional canvas frame production.

Acceptable Knots Are Controlled, Not Unrestricted

Economy pine does not mean that all knots or timber defects are accepted. The timber is still inspected before and during production.

Acceptable knots: Small, tight and sound knots that do not negatively affect bar straightness, profile machining, joint accuracy, frame assembly or structural performance.

Rejected defects: Loose knots, falling knots, unstable knots and serious timber defects that may affect machining, frame stability or finished product quality.

Economy Pine or Premium Knot-Free Pine?

Customers can select either economy pine with acceptable tight knots or premium knot-free pine according to their target market, product positioning and budget. Both wood grades can be manufactured according to the required stretcher bar profile, bar length, joint design and finished frame dimensions.

Designed for Commercial Canvas Printing & Wall Art Production

Commercial canvas print manufacturers often have different requirements from traditional custom framing workshops. For volume production, consistent dimensions, efficient material usage, convenient assembly and predictable production costs are important.

CR3828 is suitable for professional production of:

• Photo canvas prints
• Gallery wrap canvas
• Decorative wall art
• Home décor canvas
• Retail canvas products
• Artist stretched canvas
• Volume stretched canvas production

Standard and customized bar lengths can be manufactured according to the required finished frame dimensions and production method.

Tongue & Groove Joint for Convenient Frame Assembly

CR3828 can be manufactured with tongue-and-groove corner joints for convenient wooden frame assembly and adjustment.

Matching wooden wedges can be supplied for corner adjustment and canvas re-tensioning. For larger finished frame sizes, matching cross bars and center supports can also be supplied according to the frame dimensions and structural requirements.

Consistent Quality for Volume Canvas Frame Production

Choosing economy pine does not mean accepting uncontrolled timber quality. For commercial and high-volume canvas frame production, consistency in timber condition, bar straightness, dimensions and joint machining remains important.

Our production and inspection process focuses on:

• Raw timber quality and visible defect inspection
• Knot condition and location
• Timber condition and moisture control
• Bar straightness
• Profile width and depth
• Bar length tolerance
• Tongue-and-groove machining accuracy
• Surface machining and sanding
• Corner assembly fit
• Finished frame dimensions
• Frame diagonal inspection
• Cross-bar and support fit
• Final packing inspection

For repeat B2B orders, acceptable knot standards, dimensional tolerances, wood grade and inspection requirements can be agreed according to the customer's specifications.

Pine Canvas Stretcher Bar Manufacturing

Wooden canvas stretcher bar production involves multiple machining and inspection stages. Raw timber is selected according to the required wood grade before cutting, profile machining, joint processing, surface finishing and final inspection.

Colors Art operates a dedicated wooden stretcher bar and canvas frame production facility of approximately 15,000 m², supporting timber cutting, planing, profile machining, mitre cutting, joining, sanding and wooden frame assembly.

Depending on customer requirements, we can supply loose stretcher bars, long-length wooden mouldings or pre-assembled wooden canvas frames.

Stretcher Bar & Canvas Frame Packing Options

Loose Stretcher Bar Packing

Loose wooden stretcher bars can be packed by size in bundles or reinforced cartons. This packing method provides efficient container utilization and is suitable for customers assembling canvas frames locally.

Pre-Assembled Canvas Frame Packing

For customers purchasing finished wooden canvas frames, assembled frames can be nest-packed and palletized according to frame dimensions, order quantity and transportation requirements.

Bulk Production & Container Loading

For volume B2B orders, product specification, packing method and container utilization can be considered together. Loose stretcher bars and assembled canvas frames can be packed according to the customer's order structure and shipping requirements.

For customers purchasing multiple frame sizes, packing and loading plans can be arranged according to the size mix and order quantity to improve container utilization.

Economy or Premium: Which Stretcher Bar Should You Choose?

For many commercial canvas printing companies, the economy version provides a practical solution because small, stable knots are normally hidden after the canvas is stretched over the wooden frame.

If your finished product requires a cleaner timber appearance or your internal purchasing specification requires knot-free material, premium selected pine is the better option.

If you are unsure which wood grade is suitable for your production, you can send us your current stretcher bar specification, photos or samples. We can evaluate the profile, wood grade and production requirements before recommending an option.

Frequently Asked Questions

Are pine stretcher bars with knots cheaper than knot-free pine stretcher bars?

Generally, allowing carefully controlled small, tight and sound knots reduces the level of timber selection required and can therefore provide a more economical raw-material option than specifying completely knot-free pine.

Does economy pine mean low-quality stretcher bars?

No. Economy pine refers to a different wood selection standard. Small, tight and stable knots can be accepted, while loose knots, falling knots and serious defects that may affect machining, straightness, assembly or frame performance are rejected.

Can CR3828 be manufactured in knot-free pine?

Yes. CR3828 can also be produced using selected premium knot-free pine for customers requiring a cleaner and more uniform timber appearance.

What is the CR3828 stretcher bar profile size?

CR3828 has a nominal profile of 38 mm depth × 28 mm width. The 38 mm depth provides a gallery-wrap appearance, while the economical 28 mm width helps control timber consumption and finished frame weight.

Can you manufacture custom stretcher bar lengths and frame sizes?

Yes. Standard and custom bar lengths, finished frame sizes, cross bars, support bars and OEM wooden profiles can be manufactured according to customer requirements.

Can you supply assembled canvas frames instead of loose stretcher bars?

Yes. Customers can order loose stretcher bars for local assembly or pre-assembled wooden canvas frames according to their production and logistics requirements.
