Co-Extrusion Technology

3 Core Boards

Our premier structural achievement. Using advanced co-extrusion technology, we sandwich a lightweight, high-strength core between two solid, ultra-dense PVC skin layers. Delivering superior screw anchorage and zero structural bending under heavy wardrobes and panels.

Technical Specifications

High Bending Strength & Screwholding Core.

The dual-skin co-extrusion technology prevents screws from slipping or stripping under continuous weight loads, making it the only synthetic board that completely replaces plywood in modular structural framing.

High screw pullout capacity

Resists up to 1400 N of screw extraction force, safeguarding door hinges against sagging over long periods.
