Custom Stretched Canvas in All Shapes & Sizes

Engineered to Last

All of our professionally engineered strainers or keyable custom stretched canvas frames have a front fall or slope to keep the canvas from contacting the frame except at the edge.

Top quality machining

Expert CNC design and quality machinery allow us to precisely carve any shape you require! Our standard round frames offer your most economical options.

Designed for transport

Custom stretched canvas can be designed for easy reassembly, and shipping in a compact, well protected package. This design feature makes it possible to ship large-sized frames by courier at very reasonable prices.

Stretched & Prepared Canvas in Any Shape or Size Leaves You Free to do What You Do Best - Paint!

How would you like to take the time consuming work of stretching canvas off your plate, but still know that your canvas is being prepared properly?

We design and manufacture canvas stretchers in every size, shape and volume imaginable. Then, we stretch and prepare them to exacting specifications for professional artists like you. All you’ll have to do is paint!

Our stock stretcher frame profiles range from 3/4″ to 3″ thick, and we can create any custom depth that you wish.

Are you looking for a shaped canvas: round, oval, arched, or a custom design that your imagination conceived? Check out some of our previous work here, and know that we can make any shape or thickness you need, then stretch it for you with cotton or linen, primed or unprimed, in multiple different weights and qualities.

We also make and install gravity bars, which make it easy for you to install your custom stretched canvas in your studio or gallery.

All custom canvases are shipped in well-protected carton containers, and we're shipping across North America daily. Our turnaround times range from a few days to a few weeks.

Client Feedback

When I needed a very large stretched canvas for a public commission, I wanted to make sure that it was professionally assembled and stretched so that it could be painted on, moved easily, and hung perfectly without worrying about warping or unevenness. The frame is strong and square yet light enough that it allowed me to work on it in two different locations and the canvas was stretched so neatly that the surface was tight and even, and all the edges are clean and smooth.

Both my client and the professional curator who hung the piece in its public location liked my work but were also impressed by the quality of the stretched canvas. Thanks again!

Everything went smoothly and I just got a chance to open the crate and take a look at the canvases. You have done a great job and I would like to say thank you for making my life easier. The fact that they are strong and light weight at the same time means a lot to me.

-Reza Darakshani, Painter & Musician - Austin, Texas

I had great success with your stretcher bars in Bermuda last year during my artist-in-residency. They did not warp, bow, or crack, as did most other stretcher bars in that humid climate.

I am moving to Bermuda soon. I am going to need more of your superb product.
