With reference to FIG. 2, a preferred form of the invention comprises a reinforcing element for use in strengthening and stiffening wooden beams 6. The reinforcing element comprises a length of angles steel 1 attached to an offset nail plate 2. The angled steel 1 is laid against the wooden beam 6 and the nails 9 of the nail plate 2 are driven into the wooden beam 6. The reinforcing element may have a number of nail plates spaced along its length, or alternatively a single nail plate extending substantially along its entire length. In some modified forms of the reinforcing element 7 the nails 8 may extend from immediately behind the angled steel rather than from an offset plate.
