LALNIR C25U45)

Description

C25U45 – Lalnir perforated sheet metal Lalnir impressive aesthetics with protection and strength. Composed of square holes measuring 25 mm on each side, evenly spaced at 45 mm intervals, it forms an orthogonal pattern designated Qg25-45, with a transparency rate of 30%. This balanced percentage of open area, combined with a large residual material of 20 mm between each opening, gives the sheet excellent mechanical strength, superior to that of more openwork models such as C10U14 or C16U20. The clean, angular 25 mm square hole gives the perforated panel a strong visual presence. The resulting perforation pattern has a contemporary, rigid, and structured appearance, while creating a striking graphic rhythm in the decoration. Up close, the pattern evokes a robust mesh, while from a distance, it creates a dense and controlled architectural effect. The C25U45 perforation pattern is ideal for projects where the management of empty space cannot compromise the strength of the panel or reduce the protective screen effect. The play of square shadows and light projected onto the floor provides a geometric, regular, and clear variation in light intensity. Unlike classic round perforated patterns, the orthogonal line arrangement of C25U45 perforated sheet metal allows for a precise and predictable reading of the pattern, which facilitates layout control in architectural or industrial projects requiring visual rigor and perfect repeatability. Thanks to its 20 mm solid bridges between each opening, C25U45 perforated sheet metal – Lalnir perforated sheet metal Lalnir exceptionally robust. It is highly resistant to bending, wind, and impact, and can be used in large dimensions without risk of bending or deformation, even without a supporting frame on formats larger than 2 m². This resistant perforated sheet metal is therefore particularly recommended for outdoor use in exposed environments, such as: - Ventilated facades, secondary cladding, or sunshades. - Security fences or technical perimeters in urban areas. - Robust cladding for technical rooms or industrial equipment subject to impact. - Cladding for street furniture in densely populated areas (bus shelters, protective boxes, bollards, etc.). The price of C25U45 – Lalnir perforated sheet metal, made of 1.5 mm galvanized steel, ranges from €45 to €65/m² for an order of approximately 100 m², and will be adjusted according to the finish, layout, and cutting constraints of the project.

Uses

C25U45 – Lalnir perforated sheet metal Lalnir easily distinguished by its regular structure of 25 mm square holes, arranged in a straight line every 45 mm. This Qg25-45 orthogonal pattern gives the sheet a moderate transparency of 30%, ideal for applications requiring strong physical protection, partial visual privacy, and good mechanical stability. This perforation pattern is decidedly more structural than decorative: the arrangement of the holes ensures remarkable rigidity, making the sheet metal perfectly suited to demanding uses in public and industrial environments, where it is subject to impact or vandalism. With a thickness of 1.5 to 3 mm compatible with heavy mechanical loads, C25U45 perforated sheet metal is ideal for industrial site fencing, high-risk logistics areas, police station surroundings, sensitive public facility perimeters, or local authority fencing. Its 30% perforation pattern provides a degree of transparency without being opaque, allowing for visual surveillance while blocking prying eyes and physical intrusions. The adjusted opening of C25U45 perforated sheet metal makes this openwork design a good protection solution for: - electrical enclosures, cabinets, or terminals, - compressor units, - sensitive storage areas or technical boxes. C25U45 perforation provides sufficient natural convection while protecting industrial equipment from stone chips, impacts, or external projections, especially in urban environments. Used on buildings with ventilated facades, C25U45 perforated sheet metal acts more as a moderate filter, like a dense sunshade, especially for facades facing southwest. Its square pattern gives it a rigid, industrial graphic style, well suited to sober and functional architectural projects. As a balcony railing, C25U45 perforated sheet metal is very well suited for use in public housing.
