A new product is on the rise here at KeenArt Media and this article will help break down how it works as well as all its pros and cons. An Aluminum Stretcher Bar made by the Jack Richeson Group is the next best thing to come to stretcher bars. While it may look very similar to a regular stretcher bar, it does have its differences and perks.
The new Aluminum Stretcher Bars are created out of kiln dried Pine and recycled Aluminum. The pine wood frame sits on the outside of the aluminum frame, and creates a classic smooth rounded edge as well as provides a solid surface for stapling a canvas onto. The added metal frame on the inside guarantees a heavy-duty, strong, stable structure which is perfect for large canvases. When the canvas is attached, it will sit ½” away from the bars, preventing the appearance of ghost lines. Together these two frames create both a perfect 90 degree angle and a straight edge. The Aluminum Stretcher Bars come in three main styles; Gallery Wrap Bars, Heavy Duty Bars, and Pro Bars. Both the Pro bars and Heavy Duty bars can come as short as 11” and up to as large as 144” whereas the Gallery Wrap bars only come as large as 120”.
The benefit of using aluminum stretcher bars over regular wood stretcher bars is that the metal will hold the wood in place for centuries. As time goes on, the metal will never warp, twist, or bend guaranteeing a long lasting pristine conditioned frame unlike a regular wood stretcher bar. Combining both the metal and wood frames only elevates the stretcher bar as it doesn't lose the traditional manner of assembly and production, but instead adds more stability and extends the artwork's lifetime. As well, these frames are keyable meaning additional support can be added using Key Corner Supports. These keys attach to the inner corners of a canvas and are able to re-stretch a canvas if required. This is done by expanding the corners of the canvas, ultimately tightening a possibly loose canvas. As well, this can be reversed to relax the canvas back to its original tensions if need be.
Although the aluminum stretcher bars have a long list of benefits, there are some other things to consider. Since the materials used are greater, this can lead to a greater sum in price. While the bars are more likely to last and benefit you in the long run, it is worth noting that it may be a bit of an investment compared to regular wood frames. Aside from pricing, the bars may have a wide variety of lengths however there is not a wide variety of profiles to choose from. The aluminum bar has a set profile of a 1 inch depth whereas the wood frames do vary depending on style. The Pro Bars have a wood frame depth of 1 ⅜, the Heavy Duty bars have a wood frame depth of 1 ⅜, and the Gallery Wrap bars have a wood frame depth of 2 ¼. There are no other options for the different styles. In contrast, the wood stretcher bars already offered at KeenArt Media come in a variety of profile depths such as 7/16, ⅝, ¾, ½, 1, 1 ⅛, 1 ¼, 1 ½, 1 15/16, 2, 2 ½, and 3 inches. These sizes are available for pre assembled stretcher bar frames as well as unassembled stretcher bars.
