WPC Outdoor Structural Board is a wood-plastic composite profile for outdoor platforms, walkways, stair treads, terraces and landscape structures. The standard formulation contains 60% wood fibers, 35% HDPE and 5% additives. Solid and hollow profiles are available in defined sections and lengths for different construction requirements.
Material Composition
Wood Fiber Content
Wood fibers account for 60% of the standard formulation. The fiber component forms the wood-based part of the composite and supports consistent profile formation during extrusion.
HDPE Matrix
HDPE accounts for 35% of the formulation. It forms the polymer matrix around the wood fibers and contributes to moisture resistance and profile stability in outdoor conditions.
Additive Package
Additives account for 5% of the standard formulation. The additive package supports processing, surface characteristics and material consistency during production.
Board Structure
Solid Profile
The solid profile has a continuous cross-section through the board. It is suitable for applications where section rigidity, fixing stability and concentrated loading require attention.
Hollow Profile
The hollow profile contains internal cavities to reduce profile weight and material consumption. It can be selected where the required section performance permits a lighter construction.
Section Selection
Section size should be considered together with support spacing, board orientation, fixing method and application conditions. These factors determine how a profile is used within the supporting structure.

Performance for Outdoor Construction
Moisture Exposure
The HDPE-based composite structure is suitable for exterior areas exposed to rain and humidity. Drainage, ventilation and installation spacing should be considered as part of the complete construction system.
Dimensional Control
Consistent profile dimensions help maintain board alignment during installation. Section size, fixing positions and movement allowance should be coordinated with local installation conditions.
Surface Wear
The embossed surface provides defined texture for exterior walking and landscape areas. Surface selection can be matched with traffic conditions and project appearance requirements.
Load and Span Considerations
Support Spacing
Support spacing should be established from the selected board section, installation direction and expected loading conditions. The same profile may require different support arrangements in different structures.
Concentrated Loads
Stair treads, raised platforms and other point-load areas require attention to board thickness, support positions and fixing locations.
Installation Direction
Board orientation affects the way loads transfer to the supporting frame. Installation drawings should define board direction and support layout before quantities are finalized.
Typical Applications
Outdoor Platforms
Used for raised platforms, access areas and exterior structures where a defined WPC board profile is required.
Walkways and Terraces
Suitable for garden paths, terraces, courtyards and exterior circulation areas requiring consistent board dimensions and surface finish.
Stair Treads
Solid profiles can be selected for stair tread applications where a continuous section and controlled fixing arrangement are required.
Landscape Structures
Applicable to planter structures, raised landscape elements, seating platforms and other outdoor construction components.
Surface and Color Selection
Wood-Grain Finish
Embossed wood-grain surfaces provide a defined texture and consistent appearance across installed boards.
Color Matching
Standard colors are available for project selection. For installations using material from multiple production batches, color confirmation before production helps maintain visual consistency.
Processing and Installation
Cutting
Profiles can be cut to project lengths using suitable woodworking-compatible cutting processes. Accurate cutting supports consistent joints and repeated board layouts.
Fixing
The fixing method should match the selected profile and support frame. Board spacing and movement allowance should be established according to the installation environment.
Site Handling
Boards should be stored on level supports before installation. Controlled stacking helps maintain profile condition during transportation, handling and site preparation.
Quality Control
Material Consistency
Wood fiber, HDPE and additive proportions are controlled during material preparation to maintain consistent extrusion conditions and profile composition.
Profile Inspection
Finished boards can be checked for section dimensions, length, surface condition and visible profile consistency against the specified production requirements.
Batch Control
Production records can identify material specification, profile section, color and batch. This supports controlled allocation when one project requires consistent specifications across multiple production runs.
Custom Specifications
Section Dimensions
Custom width and thickness can be reviewed according to the application, support arrangement and extrusion requirements.
Length
Standard lengths range from 1.8 to 5.9 m. Project-specific lengths can be reviewed where installation layout or material utilization requires a different format.
Surface Requirements
Surface texture, embossing pattern and color can be specified according to the required appearance and installation system.
FAQ
Q: Is the board available in solid and hollow profiles?
A: Yes. Both structures are available. Selection depends on section requirements, support arrangement, fixing method and application conditions.
Q: What standard lengths are available?
A: Standard lengths range from 1.8 to 5.9 m. Other lengths can be reviewed according to the required specification.
Q: Which profile is suitable for stair treads?
A: Solid profiles can be considered where a continuous section is required. Final selection should account for tread dimensions, support positions, fixing method and loading conditions.
Q: Can the board dimensions be customized?
A: Yes. Custom section dimensions can be reviewed according to required width, thickness, application and production requirements.
Q: What information is needed for a quotation?
A: Section size, profile structure, length, surface, color, quantity and application are useful for specification review. Support spacing and loading information should also be provided for structural applications.
