Aluminum Stretcher Bars
We are pleased to offer premium aluminum stretcher bars to our audience across Canada and the United States. These architectural-grade aluminum stretchers have been used widely throughout Europe and North America by world-renowned artists and hobbyists alike for more than 20 years. Now, they're available online exclusively with UCSart.com in sizes from 24-96” (~61-244 cm). Please email or call us at 1-800-561-4944 to purchase any size outside of that range.
Available in two thicknesses, 40mm (1.57") and 27mm (1.06"), these stretcher frames are ideal for very large canvases (up to 50 ft and more!). Aluminum bars fitted with plywood permit stapling of the canvas, and a mechanical keying system for the corner joints and each brace allows for fine-tuned adjustment of tension throughout the canvas. These aluminum frames are easily taken apart and reassembled, making it possible to move, ship, and store even oversized canvases. These stretchers will maintain their integrity through adverse conditions and have a high degree of resistence to corrosion.
Typically, aluminum stretcher frames offer advantages in the following situations:
where large canvases needs to be stretched on a relatively thin stretcher frame
where exposure to large variations in heat and moisture levels exist (outdoors, or in tropical and cold climates)
where tolerances for movement within the stretcher frame are very small
where fire code regulations make the use of wood stretchers unacceptable
There is a misconception around the weight of aluminum stretcher frames. Many people assume an aluminum frame will be lighter than an all-wood frame, however, this is not usually the case. While aluminum is one of the lightest metals available, a frame made entirely out of aluminum will generally be 30% to 50% heavier than one made of wood. Aluminum stretcher bars can be made thinner than equivalent wooden ones but the weight will be greater.
The cost of making aluminum frames is also higher than all-wood designs, mainly due to the higher cost of materials and machining.
The photos below show some of the aluminum and wood aluminum hybrid stretcher frames we have made. If you think that aluminum stretcher bars might be a good choice for your project, please call us so we can discuss the details of your artwork and installation.
