  • These terms are often used interchangeably but the difference is simple. A stretcher bar is expandable while a strainer bar is locked in a fixed dimension. Stretchers are used when there may be a need to increase tension on the substrate at a later time. Stretchers also can generally be disassembled while strainers usually are fixed with glue and fasteners. Our wood strainers are our most affordable armature. Learn more about our stretchers and strainers on our Products Page.

  • One of the most common substrate questions we get is “Should I paint on linen or cotton canvas?” With the price of linen being significantly higher than cotton canvas, it’s a fair question. Personal preference is the simple answer. Many painters feel that one substrate just performs best for their specific practice. Outside of preference, a painter might choose linen over cotton canvas simply for prestige. When aiming for the highest level of success in the fine art world, elevating your work with the status of a premium substrate can make the difference in getting noticed. Learn more about all of our available substrates on our Stretching, Substrates, and Surfacing Page.

  • Another common question is “Should I switch from wood bars to aluminum?” There are clear pros and cons when deciding between the two materials. Our aluminum bars are a truly premium product - expandable, fully collapsable, and heavy duty engineering - they demonstrate to your collectors just how serious your practice is. Our wood bars are extremely high quality as well and more economical than aluminum. Learn more about all of our armatures on our Products Page.

  • Yes, we absolutely can stretch or re-stretch finished art onto a stretcher bar, it’s a service we take very seriously. Our philosophy is that stretching a blank canvas is a fabrication process while stretching finished art is a conservation practice. You can learn more about our practices and policies on our Finished Art Stretching Page.

  • Sometimes our clients are looking for something they truly can’t get anywhere other than Custom Art Surfaces. Please visit our Custom Fabrication page to learn more.

  • We offer standard and custom profile depths for each of our products. For Wood Strainers, Panels, and Stretchers our standard depths are 1.5” and 2”. For Aluminum stretchers we offer 1”, 1.5”, and 2”. For wood products we can offer just about any custom depth for additional milling fee. When completing our Quote Request Form select the “Custom” option in the Depth field and note your desired profile depth in the Special Request section.

  • CAS is committed to providing high quality surfaces to our clients; however, in the interest of safety for our team we limit the surface media we are willing to apply to water based products like acrylic mediums and PVA. Many of our clients who wish to work on oil primed material choose to source pre-primed canvas that we keep on hand and stretch for them. If you’re interested in sourcing your own material, please note that in the Special Request section when completing our Quote Request Form.

  • Sure! It’s common for galleries or collectors to cover the cost of canvases for their artists. Ask your gallerist if they’re able to cover or front the cost of your next solo.
