Metwood SQUARE COLUMNS™ are a perfect match for TUFF BEAM™, but the fact is they’ll support just about anything. SQUARE COLUMNS™ have many advantages over round columns. Metwood SQUARE COLUMNS™ are used in both TUFF FLOOR™ and TUFF DECK™ products. SQUARE COLUMNS™ feature a higher strength to weight ratio, and offer a more convenient means of attaching finish materials at a price comparable to round columns. They can be cut to length on the job site and easily assemble using self drilling screws.
