INTEX Extruded Rail Systems

Leverages World-Class Engineering and Design

Low Maintenance

INTEX Cellular PVC products are impervious to the elements. They offer durability that far surpasses wood or other materials, which are affected by moisture, changing temperatures, UV light and insects. This can cause them to warp, rot, swell, or split.

Beautiful Design

The white finish of INTEX Cellular PVC millwork looks beautiful and will stay that way for many years. But, if you want to express your design ideas in color, INTEX millwork can be easily painted. In fact, its brushed surface accepts paint better than wood.


INTEX is a family company who values trusted relationships, no matter how basic or complex the project. Builders, contractors and architects enjoy peace of mind that comes with a manufacturer they can trust.
