ROTANA (H40Z50)

Description

H40Z50 perforated sheet metal – Rotana a metal honeycomb screen with a regular hexagonal geometry at 120°, creating a graphic and highly breathable mesh. The H40 hexagonal openings (≈ 40 mm flat cell) are arranged in a Z50 staggered pattern (50 mm triangular mesh), for an operational void of around 50%. This level of transparency promotes sustained airflow, generous light transmission, and a marked visual lightening of the envelope, while preserving a clear geometric reading. The staggered pattern diffuses the openings without any particular direction: from a distance, the perforated surface appears as a uniform metal veil; up close, the hexagonal perforations produce a soft, non-directional pattern of shadows. Rotana perforated sheet metal Rotana for ventilated facades, cladding, decorative privacy screens, parking lot cladding, and HVAC equipment screens, as well as for trellises and false ceilings with graphic patterns. The honeycomb pattern offers a contemporary look that is more architectural than an orthogonal grid, with a good compromise between transparency and background concealment depending on the lighting. Honeycomb perforated sheet metal with a hexagonal opening H = 40 mm and a pitch Z = 50 mm, the material bridges are approximately 10 mm on the main axes, slightly less on some diagonals of the triangular mesh. This material reserve requires careful design: • for 2.0 mm steel, limit unframed panels to sizes smaller than 1 m²; • choose the installation orientation (pointed side up or flat horizontally) depending on the desired visual effect and runoff. A transparency of close to 50% provides high air flow and good light diffusion. In 2 mm thick galvanized steel, H40Z50 - Rotana perforated sheet metal generally Rotana between €55 and €98/m² for around 100 m² of supply, depending on thickness, finish, and installation pattern.

Uses

Rotana perforated sheet metal Rotana for ventilated facades, openwork railings, public site fencing, decorative privacy screens, and parking garage or technical equipment enclosures. Its generous hexagonal pattern promotes air and light circulation while maintaining a clear and structured geometric appearance. The staggered arrangement softens the grid effect and produces a fluid, rhythmic, and natural perception inspired by biological structures. This perforation, which is both open and stable, gives Rotana sheet metal Rotana role as a light filter and a strong graphic element for contemporary architecture. When used indoors, Rotana perforated sheet metal Rotana as a decorative cladding. Its hexagonal honeycomb pattern diffuses light gently and produces varying effects of transparency depending on the lighting. Combined with an acoustic veil, it becomes an openwork ceiling or wall covering that combines aesthetics and performance. This large, regular pattern provides a clear reading of volumes, ideal for high-ceilinged spaces, entrance halls, or public galleries. With a high percentage of open space of nearly 50%, H40Z50 sheet metal offers maximum natural ventilation. It is suitable for all situations where lightness and transparency must be combined with mechanical strength. The sufficient amount of residual metal ensures proper mechanical strength, even on large panels, while maintaining the necessary rigidity in the face of external stresses. When oriented vertically, Rotana perforated sheet metal Rotana an open architectural grid; when laid horizontally, it becomes a dynamic and light pattern.
