FAQ: Technical FAQ on Decorative Expanded Metal
Q1: What are the most commonly used materials for decorative expanded metal?
A: Aluminum (6061, 3003), Stainless Steel (304/316), Carbon Steel, Brass, and Copper. Each offers unique combinations of weight, corrosion resistance, and price point.
Q2: What does "LWD x SWD" denote in mesh specifications?
A: LWD (Long Way of Diamond) and SWD (Short Way of Diamond) are the main axes' measurements of the diamond-shaped opening, essential for light transmission and mechanical performance.
Q3: What surface finishes are available for decorative expanded metal panels?
A: Common finishes include galvanizing, anodizing, PVDF painting, and powder coating (RAL/Custom colors), enhancing weather and UV resistance.
Q4: What installation standards are used for decorative expanded metal mesh?
A: Installations generally follow ASTM E283 (air penetration), EN 12020-2 (framing tolerances), and BS 476 (fire resistance, if applicable). Mounting systems: concealed clips, rigid frames, or direct fasteners.
Q5: How is product accuracy and quality verified?
A: Each batch is measured digitally for strand width, thickness uniformity, and finish adhesion (pull-off, cross-cut tests); compliance certificates provided.
Q6: Can mesh opening and patterning be fully customized?
A: Yes. Advanced CNC and progressive die tooling support custom opening sizes, shapes, and multi-layer meshes for special effects.
Q7: Is expanded metal decorative eco-friendly?
A: Absolutely—most variants are 100% recyclable and, as a single-piece mesh, reduce waste compared to perforated panels or welded grids.
