Abstract
Sturdy metal strainer frames for mounting art canvas are assembled in any required size in an easy and cost-effective fabrication approach. Frame members fabricated as aluminum extrusions are joined at mitred corners to form a rectangular strainer frame. The frame extrusion pattern provides a smooth rounded perimeter edge for improved canvas mounting, a rear channel for anchoring the canvas around the edges and a larger channel around the inside of the frame for accepting brace members as required and holding them accurately aligned, typically at two foot intervals for larger frame sizes. The brace members, provided in two types of extrusion pattern, are cut to length and attached together at junctions as required and to the frame at overlapping flanges, preferably by a proprietary TOX (R) joining system utilizing an upsetting-pressing technique that eliminates all separate fastening hardware items such as clips, nuts, bolts, screws and rivets and requires no drilling, welding, or adhesives.
