BRIDIE LR 5x25 Z 13x35)

Description

The LR 5×25 Z 13×35 – Bridie perforated sheet metal Bridie an elongated and very regular pattern: oblong horizontal openings measuring 5×25 mm, arranged in a staggered pattern with a pitch of 13 mm in width and 35 mm in length. Under this standard nomenclature, the perforation geometry creates approximately 19% open area, a level measured when aiming for useful airflow, controlled light transmission, and calm visual reading. The perforated mesh in a triangular arrangement resulting from the staggered layout diffuses the openings without any preferred direction, while retaining the linear character of the oblong pattern: the shadows are deposited in fine, moiré stripes, softer than with an orthogonal grid. The 5×25 mm oblong perforated hole creates a precise and elegant visual signature that is more "directional" than a round hole. When placed horizontally, it stretches the surface and visually lightens the facades of radiator covers; when placed vertically, it accentuates the perception of height and refines the plate. This perforated pattern is suitable for cladding, technical screens, HVAC unit covers, false ceilings in corridors, and filter partitions when fine granularity, moderate ventilation, and effective background masking are required. Perforated sheet metal with a Z 13×35 pitch and a 5×25 mm opening, the material bridges are approximately 8 mm in the small direction (13 – 5) and 10 mm in the large direction (35 – 25). In a staggered pattern, the minimum slanted reserve remains comfortable, which translates into good rigidity at equal thickness: • in 1.5 to 2 mm steel, reasonably sized unframed formats remain possible depending on the exposure; • take care with the orientation of the folds (perpendicular to the long length of the oblongs to maximize strength); The 19% perforated area provides regular micro-ventilation and moderate light transmission, while significantly limiting direct views. The 5×25 mm slits reduce the introduction of objects and finger grip, which is useful in accessible areas. Made of 1.5 mm thick galvanized steel, the price of LR 5×25 Z 13×35 – Bridie perforated sheet metal Bridie generally between €52 and €90/m² for around 100 m² of supply, depending on the thickness, finish, and installation layout.

Uses

The LR 5x25 Z 13x35 – Bridie perforated sheet metal Bridie to fill guardrails, mechanical partitions, or technical grilles. The oriented oblong holes reduce visibility depending on the angle of observation, creating a variable screening effect that is particularly useful for protecting balconies, terraces, or walkways from direct view by neighbors. This optical behavior, specific to the elongated shape of the perforations, creates selective privacy: the more the gaze moves sideways, the more opaque the sheet metal becomes. This principle makes it an ideal material for residential or commercial architecture where privacy and visual breathing space must coexist. Urban architects find it a directional material, capable of directing light and modulating the perception of a space. Metalworkers see it as a strong, stable sheet metal that is suitable for precise assemblies and tensioning over large areas. Interior designers recognize it as a modular metal skin that protects and delimits while contributing to the graphic identity of the space. When used as a ceiling, Bridie perforated sheet metal Bridie a high-performance technical cladding. Combined with an acoustic veil and an absorbent material, it becomes a functional element of interior comfort: the oblong perforations diffuse sound and help reduce reverberation in communal areas, halls, corridors, and offices. It thus fulfills a dual function—aesthetic and acoustic—while maintaining a durable and easy-to-maintain metal finish. With a transparency of approximately 19%, LR 5x25 Z 13x35 sheet metal promotes controlled ventilation and partial shading, suitable for outdoor spaces as well as indoor areas requiring light regulation. The staggered oblong pattern creates a play of linear shadows and light that animates the surface depending on the position of the sun and the viewer's gaze.
