PALONE (R12T18)

Description

The R12T18 – Palone perforated sheet metal Palone the meeting of material and void in a graceful graphic composition. Its regular pattern, based on round holes with a diameter of 12 mm, follows a 60° staggered grid, with a regular pitch of 18 mm between the centers of each perforation. This regular center-to-center arrangement creates a uniform perforated grid, identified under the Rv12-18 standard, offering 40% transparency, which makes it a balanced model between light filtering effect and mechanical resistance of the panel. The production of this Rv12-18 perforated sheet metal relies on the use of 30T mechanical presses, equipped with precise and sharp cutting tools, capable of punching steel sheets from 1 mm to 3 mm thick, without altering the material or creating burrs. The 12 mm hole diameter, although common, requires rigorous alignment of the punch and die to ensure impeccable regularity. The staggered arrangement allows for better distribution of mechanical stress across the entire perforated panel and improves bending strength, especially in the case of large dimensions, such as for facade panels or metal fencing. Thanks to its regular openings, R12T18 - Palone perforated sheet metal Palone air and light to filter through, creating a play of moving shadows. This aesthetic feature makes it an ideal choice for ventilated facades, bicycle shelter cladding, or architectural partitions where natural light needs to be preserved while modulating privacy. The regularity of the pattern offers a stable and dynamic visual effect, without visual saturation for the passerby. Each steel sheet becomes a graphic element in its own right; from a distance, the perforated surface transforms into a semi-transparent, elegant, and airy metal mashrabiya screen. The mechanical strength of R12T18 perforated sheet metal is ensured by the consistency of the 6 mm residual material bridges between each hole, providing a good compromise between visual lightness and structural strength. However, for panels larger than 2 m² or for free-standing applications (without a frame), it is recommended that the perforated sheet be installed in a rigid frame to avoid the risk of buckling, or that lateral folds be added to stiffen the sheet. The 40% open area ratio maintains good resistance to wind loads while reducing the static weight per square meter. This round pattern is particularly popular in projects involving: - Facades of commercial, cultural, or public buildings. - Balcony railings or pedestrian bridge guardrails, where design and transparency are desired. - Metal fences, combining security and visual openness. - Urban or interior decorative elements (wall cladding, partitions, technical false ceilings). The price of R12T18 - Palone perforated sheet metal, made of 1.5 mm thick galvanized steel, varies between €40 and €60/m², for an average order of 100 m². The cost may vary depending on the sheet size, the type of finish (powder coating, hot-dip galvanizing), and the specific requirements of the project. For a more economical yet decorative alternative, R15T20 perforated sheet metal is an excellent option with a similar openwork appearance, but at a lower cost thanks to an optimized punching rate.

Uses

With its high open area of 40%, R12T18 – Palone perforated sheet metal Palone ideal for outdoor projects requiring high air, light, and visibility permeability while maintaining strength. 1. Openwork metal facades Used as secondary cladding on new or renovated facades, R12T18 perforated sheet metal acts as a passive sunshade. Its regular perforated pattern diffuses natural light throughout the building, reduces heat gain, and preserves an unobstructed view of the outside. The 40% transparency also ensures effective natural ventilation behind the cladding, which is a major advantage for ventilated building envelopes. 2. Terrace or stair railings For railings, R12T18 perforated sheet metal combines fall protection with visual transparency. The 12 mm round hole offers a good level of openness without compromising mechanical stability. It blends perfectly with contemporary or commercial architecture, with a highly graphic semi-openwork finish. The perforation also provides an anti-climbing solution, while maintaining visibility through the perforated sheet metal. 3. Semi-opaque fencing Ideal for urban fencing, park perimeters, or residential fencing, this sheet metal can be used to mark property boundaries. The perforated pattern allows the environment to be seen while limiting direct visual intrusion. It also provides sufficient resistance to wind and vandalism, especially in urban environments. 4. Technical enclosures, machine covers, ventilation R12T18 perforated sheet metal is perfectly suited for technical rooms, air conditioning machines, electrical transformers, or industrial ventilation grilles. Its large hole diameter promotes intense natural ventilation, which is essential for the proper functioning and cooling of equipment.
