Co-Extruded Composite Decking
High-performance co-extruded composite decking designed for durable, low-maintenance outdoor environments.
ZAUS Co-Extruded Composite Decking combines the natural appearance of timber with a protective co-extruded surface engineered for exterior applications.
The system uses composite / WPC construction with an additional protective surface layer, providing improved resistance to moisture, UV exposure, slipping and scratching while maintaining the warmth and visual character associated with timber decking.
With multiple board profiles, two documented timber-grain surface treatments and six coordinated colour directions, the range can be configured around residential, multi-residential and selected commercial outdoor applications.
Co-Extruded Composite Construction
The decking uses a co-extruded composite / WPC construction developed specifically for exterior environments.
The protective outer surface provides an additional performance layer around the composite board while creating the finished timber-look appearance.
Key characteristics include:
Moisture resistance
UV resistance
Slip resistance
Scratch resistance
Low-maintenance construction
Easy installation
Timber-look appearance
Multiple board profiles and surface finishes
Final performance characteristics should be confirmed against the selected manufacturer-supported profile and applicable technical documentation before specification.
Surface Finish Options
Two documented timber-grain surface treatments are available within the range.
EM01 — Brushed Large Wood Grain
EM04 — Straight Wood Grain
Both finishes are available across the same documented six-colour palette, allowing the grain character and colour to be selected independently according to the architectural direction of the project.
EM01 — Brushed Large Wood Grain
EM01 combines a larger timber-grain pattern with a brushed surface treatment.
The finish creates a more pronounced and naturally varied timber expression, making it particularly suited to projects where the decking is intended to retain a strong visual connection to traditional timber boards.
Available colours include:
KC001 — Teak
KC002 — Redwood
KC003 — Rosewood
KC004 — Cream Grey
KC006 — Light Grey
KC009 — Coffee
EM04 — Straight Wood Grain
EM04 provides a straighter and more controlled timber-grain pattern.
Compared with the broader character of EM01, the linear grain creates a cleaner architectural expression suited to contemporary outdoor environments.
Available colours include:
KC001 — Teak
KC002 — Redwood
KC003 — Rosewood
KC004 — Cream Grey
KC006 — Light Grey
KC009 — Coffee
Colour Selection
The documented colour palette extends from traditional timber tones through to cooler contemporary finishes.
Teak and Redwood provide warmer natural timber directions, while Rosewood and Coffee introduce deeper, richer tones. Cream Grey and Light Grey provide more neutral alternatives for contemporary architecture.
Final colour and surface selection should be made against applicable manufacturer samples, as digital representations can vary from the finished product.

Standard Decking Profiles
KR1001, KR1003A, KR1004, KR1005, KR1008 and KR1009 provide the primary decking profiles within the documented range.
Board dimensions vary slightly between profiles, allowing the appropriate construction and visual proportion to be selected according to the project.
The majority of profiles use an approximately 140 mm board width, while KR1009 provides a wider 148 mm format.
Final profile construction and compatibility should be confirmed before specification rather than assuming that profiles with similar external dimensions are interchangeable.
KR1006 — Starter Board
KR1006 is the documented 140 × 22.5 mm starter board within the system.
The profile is intended to support applicable starting or finishing conditions within compatible decking installations.
Its location and fixing method should be coordinated with the selected decking profile and manufacturer-supported installation detail.
KR1007 — Co-Extruded Thin Board
KR1007 provides a 140 × 10 mm co-extruded thin-board profile.
Its reduced thickness distinguishes it from the primary structural decking profiles within the range.
The intended application, supporting requirements and installation method should be confirmed against the applicable manufacturer documentation before specification.
Exterior Performance
The co-extruded surface is designed to improve the performance of the composite board under exterior conditions.
Documented characteristics include:
Moisture resistance
UV resistance
Slip resistance
Scratch resistance
Low-maintenance surface
Exterior durability
The system provides an alternative to conventional timber decking where reduced ongoing maintenance and greater consistency of the finished surface are desired.
Where a project requires a particular tested slip, fire or other regulatory classification, the applicable result should be confirmed for the selected product before specification.
Moisture Resistance
The composite construction and protective co-extruded surface are designed to provide resistance to moisture associated with normal exterior environments.
Appropriate drainage, ventilation, board spacing and perimeter clearances remain important to the performance of the complete decking system.
UV Resistance
The protective surface is designed for exposure to outdoor environments and incorporates documented UV-resistant performance.
Long-term appearance can nevertheless be influenced by climate, orientation, exposure and maintenance conditions.
Applicable manufacturer care and maintenance requirements should therefore be followed throughout the life of the decking.
Slip Resistance
The decking range is documented as slip resistant and is intended for general exterior decking applications.
Where the installation forms part of a pool surround, commercial environment or another area requiring a defined slip classification, the applicable tested result should be confirmed for the selected profile and surface finish before specification.
Scratch Resistance
The co-extruded surface provides documented resistance to scratching associated with normal outdoor use.
Appropriate care should still be taken when moving outdoor furniture, equipment and other concentrated loads across the finished decking surface.
Environmental Characteristics
The documented product range indicates:
0 heavy metals
0 formaldehyde
Any project-specific environmental certification, recycled-content requirement or sustainability target should be confirmed against the applicable manufacturer documentation before specification.
Ten-Year Warranty
The documented Co-Extruded Composite Decking range is supplied with a 10-year warranty.
Final warranty coverage, conditions, exclusions, installation requirements and maintenance obligations should be confirmed against the applicable manufacturer warranty documentation for the selected product.
