Decking & Railings

Fortress Decking & Railing

Built on the strength of more than 50 years of innovation, Fortress Building Products is one of the strongest brands in the residential, multi-family and commercial building products industry.


Composite Decking


Fortress® set out to prove that cost-effective decking could still deliver the strength, usability and beauty of its premium cousins. Well, we did that and more.

Our new Infinity® I Series decking is 40% lighter, while keeping the same stiffness and mechanical properties. This revolutionary design uses the historically proven I-beam shape, which is uniquely capable of handling heavy loads.


PVC Decking


Fortress® imagined a radical idea. Could we build a PVC decking series that defies expectations? As a result of pushing the boundaries, our Apex™ PVC Decking reaches new heights in value, quality and aesthetics. Fortress® Apex PVC Decking uses a proprietary tri-extrusion process that delivers the beautiful look of tropical hardwoods. In fact, it's been called, “the best board I've ever seen" by numerous customers.

Fortress® Apex PVC Decking's foam core is reinforced with bamboo, making it 45% lighter than composite decking and easy to work with. It expands and contracts 25% less than other PVC decking, providing a more consistent, uniform board. Each board is also encapsulated in an acrylic polymer that delivers outstanding UV performance. This means your deck won't fade like other PVC products. And, it provides the highest non-slip rating. So, rise up and reach the apex of decking.

Aluminum Railing

by Fortress


Fortress® aluminum railings let you build smartly and boldly. Aluminum isn’t susceptible to corrosion or rust. And, it can easily hold up to tough weather, including ice, snow, rain and UV rays. Not to mention, aluminum railings won’t splinter, twist, shrink or warp. They are easy to install and require little upkeep. Enjoy elegance and style without excessive weight or expense.
