The Ecoscape Composite Decking Forte Plastic Joist is designed for professional builders and DIY enthusiasts seeking a long-lasting, reliable substructure for composite decking projects. Its primary benefit is superior longevity compared to traditional timber, as the composite material resists rot, warping, and splitting, ensuring a stable foundation for years; however, installers should note that due to its composition, it requires specific spacing requirements to ensure optimal structural integrity across the deck surface.

Yes, they are suitable for raised applications provided the sub-frame design meets structural engineering requirements for the deck height and load.
No, the composite material is naturally resistant to rot and insect damage and does not require any chemical treatments.
Yes, you can install timber decking on top of these joists, though ensure you use appropriate fasteners for the specific decking material chosen.
Yes, you can use standard power saws to cut these to length, though a high-quality carbide-tipped blade is recommended for a clean cut.
They are designed to be dimensionally stable, but always follow proper installation spacing to allow for standard thermal expansion and contraction.
Check the span distance against local building codes and manufacturer recommendations; additional support posts may be required.
Ensure you are using high-quality sharp-pointed structural screws and pre-drill pilot holes if the material is too dense for the fastener type.
For optimal setup, ensure your base—whether it is concrete, compacted gravel, or existing footings—is perfectly level before laying the joists. Use appropriate structural screws designed for composite or plastic materials to prevent splitting during installation. When planning your layout, verify the maximum span allowed between supports to maintain safety standards. While these joists do not require painting or staining, it is good practice to occasionally clear any debris or standing water from the sub-frame during annual deck inspections to maintain airflow and cleanliness under the deck boards.
