ORION (C15U21)

Description

Orion perforated sheet metal Orion C15U21 stands out with its precise, bright square pattern, offering an excellent compromise between transparency and rigidity. It is composed of square holes measuring 15 mm on each side, arranged in an orthogonal alignment with a regular pitch of 21 mm. A standard Qg15-21 perforated sheet metal, this openwork pattern has a transparency rate of approximately 51% (225 mm² of opening for 441 mm² of mesh), providing the right balance for ventilation, light filtration, and a controlled visual presence. The clear, regular grid pattern gives the sheet a contemporary look that is compatible with both commercial architecture and industrial and urban facilities. The 15 mm square holes, which are smaller than the very open perforation standards, create a fine metal mesh that is visible from a distance while producing a textured and elegant metal mesh effect when viewed up close. Unlike round or staggered perforations, when exposed to sunlight, the square grid creates clear orthogonal shadows and an almost "pixelated" effect that enhances urban facades, cladding boxes, equipment guards, and decorative ventilation screens. The visual perception is less pronounced than with larger openings, making Orion C15U21 perforated sheet metal suitable for mixed environments where a graphic presence is desired, but without being overly visually intrusive. With a center-to-center distance of 21 mm for a 15 mm opening, the residual material between perforations is 6 mm. This ligature, which is greater than that of very open grilles, ensures better mechanical strength for the same thickness. Made of 1.5 mm steel, unframed panels of moderate dimensions maintain satisfactory flatness; Beyond approximately 0.8 to 1.2 m², a peripheral frame, stiffening folds, or an added framework is recommended, especially outdoors or in areas subject to stress (wind, impact, vibration). For larger formats, increased thickness or a more rigid material (3 mm aluminum, 2 mm steel) will secure the structure. Finishes: Z275 galvanized steel for strength and versatility; polyester powder coating for UV durability and color signature; aluminum for weight savings on large spans. Indicative budget: in 1.5 mm thick galvanized steel, Orion perforated sheet metal Orion – C15U21 perforated sheet metal generally costs between €52 and €78/m² for an order of around 100 m², depending on the thickness, finish, layout, and installation constraints. This pattern offers a very practical balance: more than 50% open space for controlled rigidity, a precise graphic finish, and easy installation thanks to a regular grid.

Uses

C15U21 – Orion perforated sheet metal Orion characterized by balanced perforation, neither solid nor completely open, offering a happy medium between visual filtering, security, and natural light diffusion. With its 15 mm squares arranged in regular lines and an opening ratio of around 51%, it is ideal for projects where a measured presence is required, a perforated grid that protects without isolating, that shows without revealing everything. It is naturally at home in the ventilated facades of public buildings, fences in quiet urban areas, and the envelopes of technical premises where perception must be controlled but never crude. Its relatively dense material retains good rigidity, allowing for large self-supporting panels without excessive deformation. This robustness, combined with moderate openness, makes it a suitable candidate for school zones, inner courtyards, residential terraces, or sports facilities where visual security must be combined with conviviality and interaction. The visual rhythm, tighter than very open openwork patterns, produces an impression of continuity, almost textile-like, inviting gentle reading rather than graphic impact. This regular mesh is ideal for sober architecture, light-colored facades, and refined interiors where a metal surface without excessive industrial rigidity is desired. C15U21 perforated sheet metal creates calm shadows, discreet lines, and a regular canvas that is easy to integrate, lay out, and extend. Here, Orion sheet metal Orion a language of measurement, a graphic silence. The standard C15U21 – Orion pattern Orion as controlled moderation. It seeks neither the impact of fullness nor the immateriality of emptiness. It establishes a calm, rigorous presence that serves architectural intentions.
