Ultra‑Raw Steel Perforated Metal Grille Panels are engineered for high-end interiors where the industrial aesthetic, ventilation performance, and acoustic mitigation must coexist. Ideal for lofts, boutique stores, and exposed-structure renovations, these panels deliver authentic raw steel character alongside functional airflow and noise control.

Product Description

Constructed from 2 mm cold-rolled S235 carbon steel, panels feature 3 mm perforations on 10 mm pitch (~20% open area) to balance ventilation efficiency and structural rigidity. Panels are pre-treated with light ox-patination to achieve controlled colour ageing while minimizing rust staining. Flush-mounted with concealed frames, the panels integrate seamlessly with exposed beams and structural elements. The solution combines architectural authenticity, acoustic attenuation, and reliable airflow control, suitable for premium loft interiors and industrial-style renovations.
