Product Information

Full details

The Ecoscape Forte Plastic Joist is designed for professional contractors and DIY enthusiasts looking to create a durable, long-lasting sub-structure for composite decking. Its primary benefit lies in its synthetic composition, which eliminates the risks of rot, splitting, and warping commonly associated with traditional timber joists. While these joists offer exceptional stability, users should note that they require specific fastening techniques compared to wood due to their high-density plastic construction.

FAQs

Can I use these joists for a balcony or raised deck?

These joists are intended for deck sub-frames, but always consult with a structural engineer if the deck is elevated to ensure compliance with local building regulations.

Do I need to treat the joists with wood preservative?

No. The Forte Plastic Joist is synthetic and immune to rot, meaning it requires no chemical treatments or preservatives.

Can I use standard deck screws?

We recommend using high-quality stainless steel screws designed for composite decking to ensure longevity and prevent corrosion.

How do I join two joists together?

Joists should be joined over a support point (such as a pedestal or post) to ensure maximum structural support.

Are these joists fire resistant?

While durable, plastic-based products have specific fire ratings. Please check Ecoscape's technical data sheets for fire performance certification if required for your location.

Troubleshooting

Screws are stripping the plastic hole

Reduce your drill's torque setting and ensure you are using the correct diameter screw. Consider pre-drilling a slightly smaller pilot hole.

Joist seems to expand significantly in direct sun

Always leave a small expansion gap (approximately 3-5mm) between joist ends when joining them to allow for natural thermal movement.

Pros and Cons

Pros

Superior resistance to water damage and rot
Maintains structural shape over time without warping
Zero maintenance requirements after installation
Compatible with a wide range of composite decking boards

Cons

Higher initial cost compared to pressure-treated timber
Requires specific fasteners for optimal grip
Not intended for structural load-bearing applications like house framing

Setup, Compatibility & Care

Planning: Layout your joist spacing according to your specific decking manufacturer's instructions, typically at 300mm or 400mm centers.
Cutting: Use standard woodworking tools. Ensure you wear appropriate eye protection as the material may produce fine plastic shavings.
Fastening: Use high-quality stainless steel screws compatible with composite materials. Pre-drilling is recommended to prevent the plastic from potentially splitting under extreme torque.
Support: Ensure the joists are supported by a solid foundation, such as concrete pads or adjustable pedestal feet, to maintain a level surface.
Care: These joists do not require cleaning, but ensure your drainage design allows water to flow away from the base to prevent debris buildup around the joists.
