ACT Composite Lumber


Every project requires selecting the best construction material for the job. All factors must be weighed appropriately including lifecycle considerations, maintenance costs and susceptibility of the installation to environmental damage. This section of the website lists inherent properties of ACT composite timber, and how it can benefit your project. 

The key element to ACT Composite Plastic Lumber is its engineered structural composite construction. A composite combines at least two distinct materials in such a way that neither material completely merges with the other and the combination creates a system that provides benefits such as:

  • Improved strength
  • Dimensional stability
  • Superior durability


Fiber-reinforced plastic or polymer (FRP)

Fiber-reinforced plastic or polymer (FRP) composites are defined as the incorporation of a reinforcement (such as fiberglass strands) into a polymer (plastic) matrix such that the reinforcement offers a discernible reinforcing function in one or more directions. ACT Composite Plastic Lumber is manufactured using FRP composite technology that combine all of the inherent benefits of plastic for maintenance free long-term durability with reinforcements that provide strength characteristics common to wood.

"Composite" building construction is not a new concept. For thousands of years, civilizations throughout the world have used basic elements of their surrounding environment in the fabrication of dwellings. For instance, bricks were originally made from mud and straw with the mud acting much like the resin in fiber-reinforced polymer (FRP) composite construction and the straw acting as reinforcement to hold the brick together during the drying (and shrinkage) process of the brick. What FRP composites bring to the table is a versatile material system that is formulated to be nearly impervious to all environmental factors while also being environmentally-friendly.  In addition to these advantages, further benefits of using ACT Composite Plastic Lumber for your installation include:

  • Higher tensile strength and impact resistance over unreinforced plastic lumber
  • As easy to install as other wood and non-wood materials
  • Superior durability over treated wood
  • Increased service-life of structure over treated wood installations
  • Reduced maintenance costs due to its inherent resistance to:
    • Environmental factors such as freeze-thaw cycles, UV rays, expansion/creep and salt/fresh water exposure 
    • Corrosive agents, including de-icing salts and petroleum-based products
    • Wood-boring insects such as marine borers and termites
    • Moisture. ACT Lumber will not rot, splinter or decompose and never requires waterproofing
    • Discoloration. ACT Lumber retains its colorfast appearance and never needs sealing or staining


Environment benefits

ACT Composite Timber will never leach any toxic substances into the surrounding ground or water. In addition, ACT makes good use of a recycled waste, requires no special disposal and is fully recyclable. ACT Composite Timber adds resiliency measures to your project for long-term use against large storms and other natural weather phenomenons.


The Real Cost of a Project

Ultimately, the decision to specify FRP composites often comes down to cost. Although FRP composites typically have a higher product cost than most comparative construction materials, one must consider the total cost of everything associated with its lifecycle, including material + installation costs, maintenance of the operational structure and the lifetime of the product. FRP composite products are superior in a lifecycle comparison to traditional materials for most applications, and our product has a 50-year guarantee.
