Engineered to install clean.
Tarimatec decking sits on a concealed aluminium sub-frame with hidden clips — no face screws, no splinters, and a predictable, warranty-grade install.
Concealed sub-frame, hidden clips.
Boards fix to a Rastrel A aluminium sub-frame (30 × 50 mm, AW-6005 T6) with concealed clips, so fasteners never show on the surface. The result is a flush, splinter-free deck with consistent board gaps and a clean perimeter — and boards that can be lifted and re-laid if access is ever needed.
Build it to warranty standard.
Joist spacing
Correct sub-frame centres for the profile and span.
Expansion gaps
End and side gaps sized for thermal movement.
Ventilation & drainage
Airflow and fall beneath the deck to shed water.
Edge & perimeter
Fascia, start and finish profiles for a clean edge.
The technical manual is the source of truth.
Tarimatec's 25-year warranty is conditional on installing to the technical manual — joist spacing, fixing patterns, expansion gaps, drainage, ventilation and substrate requirements for both Hollow and Solid profiles. Zinodeck supplies the manual and supports builders through their first installs.
Always follow the current Tarimatec technical manual and local building codes (NBC and provincial).
