VRIZEL (R30T50)

Description

Vrizel R30T50 perforated sheet metal Vrizel an airy and measured visual design: 30 mm diameter perforated circles arranged in a staggered pattern with a constant pitch constant 50 mm. Known as standard perforated sheet metal Rv30-50, this perforation pattern provides an open area of around 33%, a balanced level when the aim is to ensure useful airflow, comfortable light transmission, and reasonable background masking. The triangular perforation pattern ensures uniform distribution of the openings: the shadow pattern remains soft and non-directional; when viewed from a distance, the surface resembles a regular, breathable metal veil. The Ø 30 mm perforated hole offers a graphic presence that is legible without being excessive. Depending on the color applied, the effect varies from a sober rendering (dark tones) to a more pronounced expression (light, metallic). The openwork pattern is suitable for ventilated facades, technical space screens, HVAC unit masks, cladding, and parking lot coverings when a compromise between ventilation, lighting, and visual privacy is desired. With perforated sheet metal with T = 50 mm and D = 30 mm, the material bridges in line are approximately 20 mm (T – D). With the triangular mesh oriented diagonally, the minimum reserve is approximately 13.3 mm (√3/2 · T – D ≈ 43.3 – 30). This generous remaining metal blade provides good rigidity and stability in service, subject to careful dimensioning: • in 2 mm steel, reasonably sized unframed formats are still possible; • for larger areas, add a welded/bolted support frame and/or stiffening profiles; • in windy locations, demanding environments (impacts, vibrations) or for large spans, aim for a thickness of 3 mm. When properly supported by a suitable frame, the triangular mesh effectively distributes stress in both axes, providing reliable support with intermediate openings. The 30 mm perforations provide substantial airflow while limiting direct views better than larger diameters. Made of 2 mm thick galvanized steel, R30T50 perforated sheet metal generally costs between €54 and €92/m² for a project involving around 100 m² of supply, depending on the thickness, finish, installation pattern, presence of frames/stiffeners, and site context. A mesh of around 33% maintains a correct mass per m² and promotes rigidity; however, the visibility of the substrate through the perforated skin should be taken into account depending on the angle and light.

Uses

Vrizel perforated sheet metal Vrizel for guardrails, fences, ventilated facade cladding, parking garage enclosures, and public facility protective barriers. Its large-diameter round pattern promotes air circulation and natural light diffusion, while creating a soft, rhythmic visual effect. In a staggered arrangement, the design avoids the rigidity of alignment and creates an impression of balanced movement. This perforated sheet metal is particularly suitable for projects where transparency and visual breathing space must be combined with the robustness of metal. With a high proportion of open space, R30T50 perforated sheet metal offers optimal natural ventilation. It visually lightens built volumes while maintaining a solid structure thanks to the balanced distribution of the remaining metal. This configuration guarantees good mechanical strength over large spans and satisfactory resistance to external stresses, particularly wind. It is a preferred solution for guardrails in multi-unit buildings, openwork facades of sports or cultural facilities, and fences in public spaces requiring controlled transparency. At close range, the material reveals the precision of the metal. From a distance, R30T50 perforated mesh fades into the light and blends into the landscape.
