MATODI (R16T18)

Description

R16T18 perforated sheet metal – Matodi the play of metallic transparency to the extreme. With its 16 mm diameter round holes, arranged in a 60° staggered pattern, every 18 mm from center to center, it forms an ultra-openwork grid designated as Rv16-18, achieving an exceptional 72% openness ratio. This hole configuration gives the metal surface a completely airy, almost floating visual effect and maximum light and air permeability, among the highest in the entire range of standard round perforations. The aesthetics of R16T18 perforated sheet metal evoke a contemporary mashrabiya, a light veil that filters views, light, and airflow as if through a minimalist metal mesh. Seen from a distance, it blends completely into the environment, disappearing entirely, like a completely translucent glass panel, producing a light, barely distinguishable shade and a striking kinetic filter effect depending on the light and the angle of observation. R16T18 perforated sheet metal is capable of appearing and disappearing completely. However, this visual finesse comes with a real technical challenge: the extreme proximity between the perforations—only 2 mm of residual material between each hole—considerably weakens the mechanical structure of the plate. Even when shaped using high-precision presses, the mechanical strength remains limited because there is too little material left on the sheet after perforation. The sheet metal cannot be used flat: it first requires reinforcement folds to avoid any risk of buckling, then a continuous support frame! A rigid frame is essential, especially outdoors or in situations involving dynamic forces (wind, impact, vibration). In interior decoration or ventilation grilles, the frame may well be optional. Industrial expertise at the limits of constraints Made from galvanized steel, Rv16-18 sheet metal is punched on 30 to 50 ton presses, using finely tuned tools with very tight tolerances. The complexity of the pattern lies in the regularity of the perforations: the large diameter combined with a very short center distance increases the risk of deformation during cutting, requiring precise tool calibration and controlled punching speed. Residual deformation can be significant, ranging from 10 to 30 mm depending on the size of the panel. It is essential to place the sheet metal on a metal or wooden frame to make the surface perforated. Precautions for use that must not be overlooked Due to its open and fragile structure, R16T18 perforated sheet metal is not suitable for: - School, public, or sensitive areas (risk of deformation due to impact), - Areas exposed to vandalism or mechanical impact, - Large freestanding panels without frames. The recommended retail price for R16T18 perforated sheet metal – Matodi 1.5 mm thick galvanized steel is between €60 and €80/m² for an order of 100 m², depending on the finish options (raw, powder coated, hot-dip galvanized) and the complexity of the layout. For a more economical or robust project, we recommend the R15T20 or R25T30 models, which offer good transparency with a void percentage of over 60% and superior mechanical strength.

Uses

R16T18 perforated sheet metal fits easily into contemporary public spaces, such as entrance halls, libraries, hotels, or shopping malls, to create openwork metal screens. It allows light, views, and air to pass through, while serving as a fluid visual barrier. In environments with a strong visual identity (fashion boutiques, showrooms, art galleries), R16T18 - Matodi perforated sheet metal Matodi be used: - as a lightweight display structure with a minimalist effect, - as a backlit openwork panel to protect light sources, The ultra-transparent perforated sheet metal creates an impressive sculptural effect while remaining lightweight and making a strong visual impact. Use in metal facades to watch out for. Rv16-18 perforated sheet metal can be used as an ultra-openwork architectural sunshade on the facades of buildings facing south or southwest. It filters light slightly, creates fluid shadow effects, and provides a graphic metallic veil, while promoting natural ventilation. Reminder: due to the very thin material between the holes (only 2 mm), this sheet metal must be installed in a rigid frame or framed panels to prevent buckling. Panel size is limited to 600 mm wide x 2400 mm long! Ventilation of technical rooms and performance of ventilated equipment R16T18 perforated sheet metal is suitable for protecting technical equipment (air conditioning units, transformers, ventilated enclosures), as it allows for maximum natural convection while providing light physical protection against splashes or intrusions. In contexts such as schoolyards, residential buildings, or high-density urban areas, R16T18 perforated sheet metal cannot be used as a security fence. In fact, transparency exceeding 45% is prohibited in high-traffic areas.
