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.
