At least a portion of (i) the first extension of the channel is inserted through a first end of the first segment of the screen bar into and substantially spaced from surfaces of the hollow interior portion thereof and (ii) the second extension is inserted through a first end of the second segment of the screen bar into and substantially spaced from surfaces of the hollow portion thereof. The rigid reinforcing and structural material, formed from a foamed chemical, is 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.
