FORTRESS – Infinity Decking

Infinity Decking is a bamboo based and fully capped, co-extruded composite. The new Infinity I-Series was an idea that came from attempting to be more efficient. Fortress wanted to cut the cost of their decking while improving the quality. By setting the goal to prove to the world that cost effective decking could still retain and deliver strength, durability, usability and beauty.
The new I-Series line from Fortress weights almost half as much as their old decking boards and to boot it maintains the same stiffness and properties of the previous boards.

The product was first developed by Eva-Last of Johannesburg, South Africa when the harsh environments of Africa proved to be too much for North American made composite products with a wood fiber core. As is often true in great stories, the inability to find a product that could meet the needs, drove the innovation and creation of a new product that is known today as Infinity I-Series Decking.

A very different approach to the composite decking manufacturing process and a truly engineered core and cap, create an extremely dense product that is unlike anything previously available. Infinity I-Series Decking has now been introduced into the markets and is quickly becoming the product of choice for architects, deck building professionals and homeowners. Patent Pending innovation has provided the decision maker the choice of our Exotic Hardwood Surface or Distressed Hardwood Surface. Consumers can get what they want whether they want the high end look of rare Ipe decking or they desire to take the popular hand scrapped hardwood look from inside the house, outside.

Four Different Colors of I-Series

Infinite Possibilities

Tiger Cove

Cape Town Grey

Oasis Palm

Caribbean Coral


I-Series Decking also allows owners to enjoy their decks knowing that they have been good stewards of Mother Earth and our limited Natural Resources. Fortress Deck avoids the deforestation of shrinking Tropical Rainforest, avoids use of lumber from our US and Canadian Forests, steers clear of virgin plastics and instead gets even better product performance with the combination of rapidly renewable bamboo and recycled plastics.


The advancements do not stop with what makes our products great on the inside but also what Fortress Deck homeowners get to enjoy with their families. Whether it is admiring the beautiful naturally variegated coloring of a finished project or the splinter free feel under their kids playing feet, Fortress Deck homeowners have the comfort of knowing they have the “best of the best” in decking products. Only available from Fortress, innovations such as variegated post sleeves and rails, full stair treads or our patent pending dual-surfaced deck boards have Fortress Infinity Decking in a new class of its own.


Fortress Deck is also putting our money where our mouth is with exceptional product coverage, providing a 25 year limited warranty and Fortress Deck Preferred Builder labor coverage. At Fortress Deck, we truly back our products and the people who buy them.
