Structural panel

A structural panel comprising:

• a. a mesh sheet having a plurality of rod portions having the same thickness and which are parallel with one another;
• b. a plurality of stiffeners, each stiffener having:
• 1. a body portion which extends away from the plane in which the rod portions lie;
• 2. a plurality of tongues each joined to the body portion by a respective bridge portion which spaces the tongue from the body portion by a distance at least equal to said rod thickness, each bridge portion lying in a plane parallel to the plane in which the rod portions lie,
• 3. each tongue extending upwardly from the bridge portion to form therewith a slot which is open-ended in a first view of the stiffener, and each tongue having a forwardly projecting portion merging into a rearwardly extending return portion to form a hook-like configuration which co-operates with said body portion to form a retaining aperture in a second view of the stiffener at right angles to the first said view;
• and
• c. a plurality of said rod portions extending through respective ones of said retaining apertures to thereby retain the mesh sheet and stiffener as an assembly, the assembly of each stiffener to a mesh sheet being effected by positioning said slots of that stiffener over respective ones of said rod portions and rotating the stiffener through an angle of 90.degree..
