Description

R4T6 perforated sheet metal - BELTOU 4 mm round holes arranged in a staggered pattern to form an Rv4-6 perforated grid with 40% transparency.

Uses

R4T6 - BELTOU perforated sheet metal BELTOU characterized by its 4 mm diameter circular holes, arranged in a staggered pattern at 60°, with a pitch of 6 mm. This geometric pattern creates a fine, harmonious metal mesh, designated Rv 4-6, with a void ratio of around 40%. This configuration provides a subtle compromise between natural ventilation, light transmission, and visual filtering, without altering the structure of the panel. While the R4T6 BELTOU model BELTOU a refined micro-perforation option, its industrial production remains delicate. The small size of the holes requires high-precision tools with extremely low tolerances to ensure alignment, regularity of the holes, and the absence of deformations or burrs at the exit of the perforating press. The finishing phase, in particular powder coating, adds to the complexity of the process. Applying powder paint to a sheet with 4 mm micro-holes requires careful measurement to avoid partial or total obstruction of the perforations, which would compromise the panel's breathability. Advanced technical expertise is therefore essential to preserve both the openwork aesthetic and the ventilation and filtration functions. This type of perforated sheet metal is therefore geared towards industrial applications and is less commonly used in architecture. The average cost of 1.5 mm thick R4T6 BELTOU galvanized BELTOU sheet is between €60 and €80/m² for an order of 100 m². For a more economical solution, consider Standard R5T8 perforated sheet metal.
