| Ventilation panels | HVAC equipment maker, building supplier | Round holes, 2–8mm diameter, 1–2mm sheet thickness | Open area %, airflow, flatness |
| Architectural facade | Architect, facade contractor | Custom hole pattern, powder coated, 2–4mm sheet | Hole pattern, aesthetics, color |
| Equipment guards | Industrial machinery maker | Round or square holes, 1.5–4mm sheet, galvanized | Hole size vs part access, sheet strength |
| Decorative interior mesh | Interior designer, fabricator | Custom decorative pattern, powder coated | Aesthetics, flatness, edge finish |
| Industrial screening | Mining, aggregate, food processing | Round or elongated holes, heavy gauge sheet | Open area, hole accuracy, durability |

| Parameter | Range / Options | Notes |
|---|---|---|
| Material | Low carbon steel, galvanized steel (confirm stainless steel availability) | Specify material grade when ordering |
| Sheet Thickness | 0.5 – 6mm | Thicker sheets for structural/industrial; thinner for ventilation/facade |
| Hole Shape | Round, square, hexagonal, elongated slot, decorative (custom) | Round holes most common and economical |
| Hole Diameter (round) | 1mm – 50mm (custom) | Smaller holes require thinner sheet for structural integrity |
| Pitch (center-to-center) | Custom per hole size and open area requirement | Pitch determines open area percentage |
| Open Area | 10% – 65% (varies by hole size and pitch) | Higher open area reduces sheet strength |
| Sheet Dimensions | Custom cut to required length × width | Standard sheet sizes also available |
| Surface Treatment | Mill finish, galvanized, powder coated, PVC coated | Powder coat: custom color on confirmation |
