Product Description
Built with a co-extruded protective layer, MacroTech GD-003 138×23mm round hollow WPC decking is designed to keep its surface cleaner, more stable, and more resistant to outdoor exposure than traditional uncapped boards. The wrapped surface helps reduce staining, moisture absorption, and visible fading, making it suitable for long-term use in terraces, garden paths, poolside decking, and commercial outdoor flooring.
The seven-hole round hollow structure reduces board weight for easier handling and installation, while maintaining a practical balance of strength and material efficiency. Its dual-sided wood grain finish gives projects more design flexibility, and the grooved edges support hidden clip installation for a cleaner deck surface with fewer exposed fasteners.

Features
One Board, More Design Flexibility
You can use one decking profile for different outdoor design needs. The dual-sided surface gives you two wood grain options, helping you match more project styles without adding extra product types to your inventory. It gives you more flexibility when supplying decking for terraces, gardens, poolside areas, and commercial outdoor spaces.
Easier Handling, Faster Project Progress
You can save time during transport, handling, cutting, and installation. The seven-hole hollow structure makes each board lighter and easier to work with, helping you reduce construction difficulty and speed up on-site progress. This gives you a more efficient decking option for bulk supply and project installation.
