Layers upon layers of concentric squares raise the interest to a high peak with our SH320 Cubism Shanko decorative ceiling tile. At first glance, these tiles appear to create a standard clean, classic look, but the many layers of the SH320 Cubism Shanko decorative ceiling tile create a much deeper and more interesting three-dimensional look that's perfect in any room, from a boardroom to a bedroom. All Patterns can be perforated for acoustical purposes Cone Head Nails are available in all Finishes. STEEL panels come UNFINISHED, and need to be treated with an OIL-BASED paint. For best results use a semi-gloss or high-gloss paint to prevent rusting or tarnishing. To leave STEEL panels in natural state, use clear gloss enamel by Rustoleum.
