Except for standard flat decorative perforated metals, we also provide perforated corrugated sheets that are stereoscopic and sound absorbing. Both of them are all attractive and affordable in architectural ornament applications. E.g. cladding wall, ceiling, curtain wall, security guard, window protection, screen & air diffuser, privacy separation, acoustics & soundproofing, louvre & ventilation. Stock sheets are available in a variety of materials, openings, material thicknesses and hole patterns for different requirements.
