Perforated sheets and expanded metal. Modern lightweight structures in architecture

08 of December '21

How to unleash the design imagination with the help of the product-visual of our time?


We tend to rightly associate the modern city with progress - not stagnation. The directions of this dynamic development are helped by the bold ideas of architects and the mastery of builders. The new face of our buildings and facades is no different, with traditional materials increasingly boldly replaced by modern, lightweight structures, such as perforated metal. This is a product of RMIG Sp. z o.o. - the world's largest manufacturer of perforated sheets and expanded metal.

Perforated sheets - innovation and beauty

Perforated sheets are a versatile product with a wide range of applications, which is resistant to corrosion and harmful environmental influences. Due to its excellent parameters, lightness and relatively low price (compared to, for example, stainless steel), such sheet metal is particularly well suited to the construction industry as a material with both technical and aesthetic values. As the world is long and wide, one can meet a multitude of constructions based on the use of this product. These include not only facades, but also ceilings, balustrades, sunshades, windbreaks, acoustic panels, or expressive wall decorations.

RMIG City Emotion concept

RMIG, through its innovative City Emotion concept, can help realize the most ambitious architectural projects that combine excitement, beauty and innovation. RMIG City Emotion is much more than simply selling perforated sheets to size - under this concept, the customer will gain support at every stage of his investment, from the idea (how to use perforated sheets?) through visualization (materials, patterns, potential effect), presentation of a sample (what it actually looks like), to production of the finished sheet. At the same time, it doesn't necessarily have to be a "bare" sheet - ultimately, perforated sheets can undergo, depending on the project, additional processing, such as laser cutting and bending, molding, powder coating or anodizing. This makes it possible to create bold, unconventional architectural visions and materialize them in modern urban space.

Perforated sheets - a sea of possibilities

RMIG offers more than a thousand types of perforated sheets. The most common product is sheet metal with round holes, but the range also includes versions of designs with square holes, among others. Both types are widely used in architecture.

Both forms of perforation work well as decorative facade covers, increase protection from the sun, for example, as infill panels on balconies and panels for balustrades. Complementing the system of perforated sheets is an elaborate way to install them easily and flawlessly in the right order. This is because RMIG uses a so-called sequential system, as well as individual numbering of the plates in the designs. This provides significant support, especially when installing a large number of perforated sheets.

RMIG expanded metal mesh

The second product besides perforated sheets that also works well in construction and industrial design is expanded metal. It is lightweight, strong, non-slip, always produced in one piece(not assembled or unwelded), plus extremely easy to work with and malleable. Suffice it to say that the façade of the National Stadium in Warsaw, almost deceptively reminiscent of a red and white basket, is a structure made of just this material, coming from the production line of the RMIG factory.

Masterful realizations

Facades and other structural elements made of perforated metal sheets manufactured by RMIG can be found throughout Europe: Denmark, the Netherlands, France, Germany, Italy and other countries. Of our Polish realizations, in addition to the capital's stadium mentioned above, it is worth mentioning Glogow's Cloth Hall - a new glazed pavilion, finished with perforated metal, on which scenes of medieval city life are depicted, brilliantly visible and pleasing to the eye especially in the evening and at night, thanks to striking backlighting. The intricate perforation patterns are an excellent example of the use of modern technology to create a historic environment.

An equally successful use of perforated sheets in a historic building is the Bismarck Tower (Bismarckturm) in Dresden. The balustrades used inside the structure with an infill of intense yellow perforated metal brightened up the interior and provided a modern look in this historic building.

RMIG ImagePerf - for advanced design challenges

At the opposite end of the spectrum of perforated metal-based projects are large, spectacular developments, such as the art school in Grimsby, with an impressive three-dimensional facade designed by Ryder Architects. As part of a major redevelopment project at the Grimsby Institute, RMIG and Ryder Architects collaborated on an impressive and artistic facade using RMIG 's advanced ImagePerf software to create a one-of-a-kind solution. The detailed design of the complex array of circular openings generates a 3D effect of the artist's original design, creating a stylish enclosure that reflects the building's purpose and intended use.

Large and small architecture with RMIG perforated metal sheets

It is worth mentioning that RMIG also does not shy away from simple but useful and life-enhancing realizations based on perforated sheets - such as the windbreak in the sea-swept Dutch town of Vlissingen. The curved sheet metal effectively protects against the wind while clearly imitating the curvature of the waves and reflecting the coastal character of this coastal town.

There are, of course, many more possibilities for the use of perforated sheets made to size from RMIG - when architects and urban planners use RMIG's City Emotion ideas, even imagination need not be the limit.
