Metal Grille & Decorative Screening: Specifying Guide
Metal grilles and screens do three jobs at once: they shade, they ventilate, and they give facades a signature texture. This guide covers the key decisions.
1. Types & Functions
- Facade grilles — sun shading, service-plant screening, architectural rhythm
- Security grilles — window/opening protection (steel bars, welded mesh)
- Ventilation louvres — airflow with weather protection
- Decorative screens — partitions, feature walls, wayfinding elements
2. Material Selection
| Material | Advantage | Use |
|---|---|---|
| Stainless 304/316 | Corrosion resistance, premium finish | Landmark, coastal, food-grade |
| Galvanized steel + powder coat | Cost-effective, colour range | General architectural |
| Perforated metal sheet | Large area, economical, controlled openness | Facade panels, screening |
3. Openness & Performance
Specify the open-area ratio for ventilation and shading (typically 30–60%), bar spacing for security and child-safety, and finish durability (outdoor powder coat or PVDF for coastal sites).
