Core Advantages
Double Layer Construction
Dual-layer design provides enhanced structural rigidity and load-bearing capacity compared to single-layer hollow decking.
Hollow Core Design
Internal hollow cavities reduce overall weight without compromising strength, making handling and installation easier.
Weather Resistance
Formulated to withstand UV exposure, moisture, and temperature fluctuations without warping or cracking.
Slip-Resistant Surface
Embossed wood grain texture provides safe walking surface in both wet and dry conditions.
Low Maintenance
No sanding, staining, or sealing required. Simple cleaning with water is sufficient to maintain appearance.
Pest and Rot Resistance
Closed-cell structure prevents moisture absorption, eliminating rot and insect infestation risks.

Frequently Asked Questions
What is the advantage of double layer hollow decking? ▶
Double layer hollow decking provides superior strength-to-weight ratio compared to single-layer designs. The two-layer construction enhances structural rigidity while internal hollow cavities reduce material weight, making installation easier without compromising load-bearing capacity.
Is double layer hollow decking suitable for heavy loads? ▶
Yes. The double layer construction provides excellent load-bearing capacity for residential decking applications. With proper joist spacing of maximum 400 mm center to center, it can support typical residential and commercial pedestrian loads.
How does double layer hollow compare to solid decking? ▶
Double layer hollow decking is lighter and more economical than solid decking while still providing good structural performance. The hollow core reduces weight without significant loss of strength, making it ideal for most residential decking applications.
What is the recommended joist spacing? ▶
For the 23 mm thick double layer hollow decking, maximum joist spacing of 400 mm center to center is recommended for residential applications. Reduce spacing to 300 mm for commercial applications or high-traffic areas.
How to clean and maintain this decking? ▶
Use a broom or leaf blower for debris removal, followed by low-pressure water rinsing. For stains, use mild detergent with water and a soft brush. Avoid pressure washers above 1500 PSI and abrasive cleaning tools.
Storage & Installation Notes
Store decking boards flat on level surface, stack height under 1 meter. Acclimate for 48 hours at site conditions before installation. Use stainless steel or coated fasteners. Leave 3-5 mm expansion gaps between boards. Warranty: 10 years against manufacturing defects.
