Type 100 square box columns
Standard POLYBOX synthetic square columns are available in all sizes and styles, such as plain, fluted, and raised panel.  Whether you need a standard size or custom shaft size, our columns are made to order, so they will accommodate any project specifications.

POLYBOX synthetic square columns are completely impervious to the effects of moisture.  You will no longer need to replace rotted, twisted or warped columns on your porch or exterior.

Type 200 and 250 square box columns
POLYBOX synthetic square columns have a smooth, blemish-free surface that takes acrylic latex or oil base paints beautifully.  The stability of the plastic composite results in a longer lasting paint job, free of checks, flaking and bleeding associated with wood columns used on porches and exteriors.

Type 300 square box columns
POLYBOX synthetic square columns are easier to cut than wood.  Unlike cast resin columns, no special blades are necessary.  They may be nailed or screwed in place and porch railings are easily attached to these polymer columns.
