The 6-wall diamond structure lock design system, developed by a technical team, is an energy-saving multi-layer sheet. Compared to the 4-wall R structure, the 6-wall D structure significantly enhances impact resistance and rigidity, while also offering high light transmittance and excellent thermal insulation properties. The standing seam design supports modular installation, effectively addressing issues of thermal expansion and water infiltration. It is available in three thickness specifications: 14mm, 16mm, and 18mm.
