137*23mm Solid Co Extruded WPC Composite Decking Heavy Duty Scratch Resistant

137*23 Heavy duty scratch resistant solid Co-extruded WPC decking

Product Summary

This professional layout highlights the heavy duty, scratch resistant solid Co-extruded WPC decking engineered for landmark commercial plazas, heavy-traffic pedestrian promenades, marine docks, and ultra-luxury estates demanding zero structural compromises. Featuring a 100% solid, high-density cross-section, it completely eliminates internal structural weak points and gravitational sagging. This robust core is permanently encapsulated within a 360-degree engineering-grade polymer shield boasting an exceptional Shore hardness. This overview directly solves common engineering failures like hollow-core cracking, edge splitting, and surface scuffing, delivering an indestructible, low-maintenance luxury flooring solution.

About this Product

• Commercial-Grade Heavy Duty Solid Integrity

• Unlike hollow-core alternatives that risk point-load fracturing, our solid Co-extruded WPC decking utilizes a 100% dense, solid cross-section. It delivers massive flexural modulus and compression strength, making it fully capable of supporting heavy commercial furniture, public maintenance vehicles, and dense crowds without sagging, snapping, or cracking.

• 360° Armor for Premium Scratch Resistance

• The outer shield is co-extruded from a highly modified polymer matrix with an advanced surface hardness profile. This scratch resistant barrier provides maximum protection against the high-frequency friction of high-heeled shoes, sharp luggage wheels, active pet claws, and the continuous dragging of outdoor equipment, ensuring the textured finish stays flawless.

• Precision CNC Edge Routing & Fabrication

• Because the board is solid from top to bottom, it offers unmatched processing security. Installers can cut, drill, angle-bevel, or perform precision CNC edge routing directly on the plank. It exposes no ugly hollow air chambers, allowing for seamless premium picture-framing edges and flawless modular stair treads.

How to Install

1. Subframe Spacing (Max 350mm)

Install your joists (wood or aluminum) on a level, draining foundation. Joist spacing must be a maximum of 350mm center-to-center to prevent the deck from sagging.

2. Lock the First Board

Screw Starter Clips into the edge of each joist. Slide the groove of your first WPC board firmly into these clips to lock the outer perimeter without surface screws.

3. Install Center Clips

Slide Hidden Fastening Clips into the inner groove of the board at every joist intersection and screw them down. These clips automatically create the mandatory 5mm side-to-side expansion gap. Slide the next board into place and repeat.

4. Manage End-to-End Joints (Double Joists)

Where two board ends meet:

• Must use Double Joists: Each board end must rest on its own independent joist and clip.

• Leave an Expansion Gap: Leave a 5mm to 8mm end-to-end gap so the boards can expand in summer without buckling.

5. Perimeter Wall Gap & Fascia

• Wall Clearance: Always leave a 10mm gap between the decking and any brick wall or solid structure.

• Finishing: Cover exposed hollow edges by screwing on a WPC Fascia Trim around the perimeter.

FAQ

Q1: Why is a solid Co-extruded WPC decking better for luxury commercial projects than a hollow co-extruded profile?

A1: Hollow co-extruded profiles are efficient for light residential use, but their internal air chambers can fail under extreme point-load impacts, such as heavy commercial staging or public trash bins. A solid board delivers consistent, uniform mechanical strength across every millimeter, offering long-term safety and removing structural liability in public spaces.

Q2: How does the scratch resistant shield on a solid board handle accidental dragging of sharp heavy iron chairs?

A2: Our scratch resistant shield has been heavily engineered with an upgraded polymer formula that features a high Shore D hardness rating. When a sharp iron chair or heavy metal table is dragged across the solid deck, the surface resists gouging or tearing the protective layer, keeping the rich woodgrain appearance uniform and unmarred.

Q3: Does a solid Co-extruded profile retain more heat or expand more than a hollow board in high-temperature plazas?

A3: While a solid profile has more physical mass—meaning it absorbs more thermal energy and retains it longer than a hollow profile—it is actually more dimensionally stable. Because it has no internal hollow air pockets that act as thermal traps, and it features an optimized crystalline core, its expansion rate is linear, predictable, and easily managed with standard expansion gaps.

Q4: Can this solid Co-extruded decking be used for water-submerged structures like floating lake docks or marine walkways?

A4: Yes. Because it is a solid profile fully sealed by a 360-degree moisture barrier, there are no open chambers to trap water, and no raw wood fibers are exposed. It is highly resistant to waterlogged structural rot, marine wood-borers, and salt mist corrosion, making it the premier choice for luxury floating docks and heavy duty marine boardwalks.
