These bars, usually stronger and larger than regular stretcher bars, are excellent for large scale requirements. They are a great solution to ensure that all the stretcher mountings are of a uniform appearance and quality.
Buying gallery wrap stretcher bars, however, is not exactly a walk in the park. When we are out there buying canvas stretcher strips and stretching bars, one of the first concerns that seem to bother us is whether they would bend or warp soon after you start using them.
Buying the best quality bars is always recommended. If you want trouble-free service for years, buy stretcher bars that have been engineered to resist the effects of heat or humidity. Dimensional stability in wood is what tends to worry us most. It is, in short, the ability of wood to stay straight and not warp or bend over time or due to pressure.
In order to ensure better stability, you should insist on buying high quality bars that use short sections, joined together with finger splines, to make longer bars. This greatly increases the bar’s resistance to twisting, bowing or warping. The system of using smaller sections also makes the bars stronger and resistant to bending than those which are entirely constructed of one continuous piece.
