MALLENE R6U12)

Description

Mallene R6U12 perforated sheet metal Mallene a fine, regular pattern: 6 mm diameter circles arranged in orthogonal alignment with a constant pitch constant 12 mm. Under the standardized designation Rg6-12, this regular perforation pattern provides approximately 20% open area, a level expected when the objective is to ensure functional airflow, controlled light transmission, and a uniform visual appearance. The linear perforation pattern produces a directional distribution of openings: shadows are formed in a regular grid pattern, with a discreet linear effect; from a distance, the surface resembles a continuous, soothing metallic veil. The Ø 6 mm perforated hole gives a very discreet and neat graphic appearance. Depending on the color, the effect varies from a muted finish on dark tones to a slightly clearer appearance on light finishes. This R6U12 perforated pattern is suitable for moderate ventilated facades, equipment covers, screens for air conditioning equipment, cladding, and technical false ceilings. With perforations of U= 12 mm and D = 6 mm, the residual material bridges are approximately 6 mm both horizontally and vertically (U– D). This comfortable metal reserve translates into good rigidity and stability in service, subject to careful dimensioning: • for 1.5 mm steel, unframed formats of reasonable size are possible up to 1.3 m²; • for larger surfaces or in demanding contexts, add a supporting frame and stiffening profiles; When properly supported by a suitable frame, the linear perforation pattern distributes stress correctly, with slightly more directional behavior than a triangular mesh, but offering excellent strength thanks to the 6 mm ligatures. The Ø 6 mm perforated holes allow for measured airflow while limiting the passage of fingers and ensuring anti-finger-pinching functionality, which is useful in areas accessible to the public or related to early childhood. Made of 1.5 mm thick galvanized steel, R6U12 perforated sheet metal generally costs between €45 and €85/m² for a 100 m² supply, depending on the thickness, finish, installation pattern, presence of frames/stiffeners, and the context of the project. A 20% open area maintains a comfortable weight per square meter and good rigidity.

Uses

Mallene DAMPERE perforated ventilation sheet metalDAMPERE separation while allowing air and visibility to pass through. With a simple pattern of repeating 6 mm diameter round holes, the panel retains high mechanical strength despite the perforations.
