We specialize in building unusual 2D and even 3D shaped canvas stretchers and supports!
The cost of a shaped stretcher/strainer frame can vary considerably depending on the size, materials, design time, etc. The following are a few past examples with sizes and approximate cost so you can get a better idea for your own projects. Note that these prices do not include a shipping crate, if required.
DID YOU KNOW?
"Stretcher" frames are keyable, allowing for additional tightening of the canvas after stretching to achieve and maintain ideal tension throughout the lifetime of the artwork.
"Strainer" frames are fixed.
Single-layer, one-piece strainers can be made up to 36"
Canvas can be stretched over panels to create a firm surface
Our new large round strainers (3-8 ft) are now available online! They break down into sections for less expensive shipping and easy assembly.
Keyable stretcher frames are made to be sectional which allows for easier shipping
Shapes with straight sides can be stretched with primed or raw canvas
Shapes with inside curves need some experimentation for stretching - in some circumstances, a spandex material has been appropriate in place of canvas. Panels are another option.
Custom arched sections can be made to fit with our regular stretcher profiles
We get asked for all kinds of creative canvases!
Large shaped sectional strainer frame
These arched frames were shipped pre-stretched in a custom crate
How large can we go for a shaped frame? So far, we're at 19 feet and counting!

TIPS FOR STRETCHING A SHAPED CANVAS:
Expert CNC design and quality machinery allow us to precisely carve any shape you require! Our standard round frames offer your most economical options.
Oval and round stretcher and strainer frames can be made to disassemble and ship in a compact, well-protected package. This design feature makes it possible to ship large-sized frames by courier at very reasonable prices.
Professionally engineered strainers or keyable stretcher frames have a front fall or slope to keep the canvas from contacting the frame except at the edge.

Since the early 1980s I have used many different heavy duty stretcher bars, from some that barely warrant the name, to others that are like finished furniture both in weight and engineering. I can’t remember how I found out about your company but I am glad I did.
The bars are made of wood that is not only absolutely straight and well measured, but are extremely strong for their low profile and light weight. Also, they take staples better than any other wood I have used, saving time and effort. I am putting together an exhibition of larger works, and your well-engineered stretcher bars are proving to be the wisest choice. Thank you!
