Aluminum Canvas Stretcher Frames
Ultimate Strength for Large-Scale Art
Built for durability, precision, and stability, our premium aluminum stretcher bars provide unmatched support for oversized canvases and challenging environments. Engineered to resist warping, withstand humidity, and ensure perfect tension, they’re the top choice for professional artists, galleries, and museums.
New SpringTite Aluminum Stretcher Bars
Perfect for very large frames or fluctuating environmental conditions — available in multiple profiles (19 mm, 25 mm, and 40 mm) for superior durability and flexibility.
Our premium architectural-grade aluminum stretchers with SpringTite™ technology are designed for artists, conservators, and institutions who need precision control and lasting stability. Available in 19 mm, 25 mm, and 40 mm profiles, they’re ideal for projects ranging from slim, floater-frame-ready canvases to bold, gallery-depth installations.
SpringTite™ is the perfect choice for:
- Large canvases where a thinner or modern profile is desired
- Challenging environments with fluctuating temperature and humidity
- Projects where exacting tolerances leave no room for movement
- Fire-code sensitive spaces where wood is not an option
- Professional work that may be restretched or reused multiple times
Every SpringTite™ frame features an integrated, tool-free tensioning system built directly into its corners and braces. This innovative mechanism allows effortless, fingertip adjustment at any time — keeping canvases tight and true over the long term, without swelling, warping, or loss of tension.
With SpringTite™, you get the same UCS precision, straightness, and corrosion-resistant aluminum as our heavy-duty bars — now with unmatched convenience and long-term control.

- where a thinner canvas is desired in a large size
- in challenging environments, including fluctuating temperature and humidity
- where tolerances for movement within the stretcher frame are very small
- where fire code regulations make the use of wooden stretchers unacceptable
- where artists wish to keep a "master frame" for painting which will stand up to repeated reuse
