KEDA (REC 5x56 Z 8x65)

Description

The REC 5×56 Z 8×65 – Keda perforated sheet metal Keda a stretched, highly breathable metal mesh pattern: rectangular holes measuring 5×56 mm, arranged in a staggered pattern with a pitch of 8 mm in the short direction and 65 mm in the long direction, create a beautiful optical illusion. With this regular perforation pattern, the open area exceeds 60%, providing a high level of transparency when the objective is to ensure high air flow in a ventilation system, generous light transmission in a privacy screen, and a marked visual lightening of the building envelope. The staggered "Z" arrangement of the perforated sheet metal homogenizes the distribution of the openings and softens the shapes to activate the mirage effect: when viewed from a distance, the perforated surface appears as a very airy metal veil, while up close, the elongated rectangular holes form a fine, directional pattern. The 5×56 mm perforated rectangle at the base of the mechanical matrix imprints a clear and contemporary graphic signature on the metal. Installed horizontally, the openwork panel accentuates the "continuous strip" effect and visually stretches the linearity of the facade; vertically, the geometric mesh reinforces the sensation of height. On dark colors, the perforation effect remains subtle; on light finishes, the veiling effect becomes more pronounced. This perforated sheet metal is defined by an 8×65 "Z" and a 5×56 mm openwork hole, with material bridges measuring approximately 3 mm in the short direction (8–5) and 9 mm in the long direction (65–56). In a staggered pattern, the slanted reserve can locally decrease to the vicinity of the weakest ligature (≈ 3 mm), which requires greater precision in mechanical dimensioning: • for 2 mm steel, limit unframed formats to small panels, less than 1 m²; • for large panels, environments subject to vandalism • orient the folds preferably perpendicular to the long side of the rectangles to maximize rigidity; When well structured, the staggered perforation distribution diffuses the forces in both axes, but the 3 mm metal ligature on the "small pitch" side remains somewhat structuring for the dimensional calculation: stability will depend directly on the thickness, frames, and mesh of the fasteners. A transparency of 62% is the maximum threshold for perforated sheet metal. Panels perforated to this maximum level provide significant air flow and high light transmission. The 5×56 mm openings limit finger grip (width 5 mm). This perforation is effective for child safety, preventing fingers from getting caught. The price of REC 5×56 Z 8×65 – Keda perforated sheet metal Keda generally between €56 and €98/m² for around 100 m² of supply, in 2 mm thick galvanized steel. The budget varies depending on the thickness chosen, the finish, the installation pattern, and the context of the project.

Uses

Keda perforated sheet metal Keda for filling railings, decorative urban fences, ventilated facade cladding, or semi-open protective screens. The staggered arrangement softens the geometry of the rectangle and subtly diffuses light, creating an optical vibration characteristic of this type of pattern. Whether used on facades or railings, Keda perforated sheet metal Keda visibility while providing a natural screening effect depending on the viewing angle. Its transparency of over 60% offers an unobstructed field of vision, while ensuring the stability and safety of the panels, even over large spans. The openness ratio of over 60% allows for near-maximum architectural transparency, with exceptional visual and light breathing space. When used indoors, Keda perforated sheet metal Keda a decorative and acoustically efficient cladding. Combined with an acoustic veil and an absorbent material, it transforms into a technical surface capable of regulating sound reverberation while allowing light to circulate. This application is ideal for metal ceilings, openwork partitions, or large public spaces where transparency, comfort, and aesthetic consistency are desired. REC 5x56 Z 8x65 – Keda perforated sheet metal Keda architectural transparency, visual lightness, and mechanical control. Its 5 x 56 mm rectangular pattern in a staggered arrangement forms a lively and balanced grid, offering high transparency, close to 60% open area, one of the most open among rectangular perforations for architectural use. This long, thin pattern creates an illusion of stretch and depth, transforming the sheet metal into a luminous metal veil, ideal for projects where transparency, breathability, and the perception of movement play a central role.
