A structural corner reinforcement for strengthening frames includes at least a first segment and a second segment of frame bar, each formed into a desired profile and each having a hollow interior portion, a reinforcing channel having a first leg and a second leg arranged at an angle to the first leg, with ends of the channel securing first and second extensions to extend the first and second legs, respectively, at least one of (i) a portion of the first extension of the reinforcing channel being inserted through a first end of the first segment of the frame bar into and substantially spaced from surfaces of the hollow interior portion of the first segment and (ii) a portion of the second extension of the reinforcing channel being inserted through a first end of the second segment of the frame bar into and substantially spaced from surfaces of the hollow interior portion of the second segment, and a rigid reinforcing and structural material, formed from a foamed chemical, inside at least one of (i) the hollow interior portion of the first segment for securing the inserted portion of the first extension of the reinforcing channel therewithin and (ii) the hollow interior portion of the second segment for securing the inserted portion of the second extension of the reinforcing channel therewithin.
