Industrial meshes / Filtration meshes
Exemplary innovative competence and the courage to keep an open mind for unconventional ideas have characterized the entrepreneurial development of GKD since the company was founded in 1925. The product range of today's business unit Industrial meshes has developed to include everything from mesh for the screening of solids to filter media for solid/liquid filtration, from shielding screens for aeroplane parts to noise-reducing acoustic insulation mesh for aeroplane engines. In terms of compliance with nitrogen oxide (NOx) thresholds, low-pressure exhaust gas recirculation plays a key role. One indispensible element in such systems are high-performance LP EGR filters made of multi-dimensional Volumetric Mesh. These protect the engine and turbocharger on the clean-air side against detrimental particles. Classic areas of application include polymer filtration for the production of fibers in the textile industry, filtration in the soft-drinks and brewing industry and process filtration in a wide range of other industrial sectors. And, particularly in the field of high-viscosity fluids, GKD's mechanically robust mesh constructions are also leading products.
Up to 600 meter long high-precise strips of fine filter media, in which wires just a quarter of the diameter of a human hair are woven, allow GKD wire meshes to be integrated directly into customer-specific automation processes, for example in the automotive industry in highly demanding electronic driving aid applications like ASP, ESP or ABS, or in the inkjet printer sector. And this business unit has now been given strong, new impetus through the most modern technical looms for fine mesh. High-tech filter media, a philosophy of holistic solutions and the capability of supplying complete filter systems for industrial and medical-technical applications will continue to consolidate the leading international position of this sector of the company.
As a systems supplier the business unit develops filtration technology and plant engineering compact filter systems for specific submarkets in the solid/liquid separation sector. The integrated compact filter system MAXFLOW combines filtration and briquetting in a single piece of equipment. Without the need for filter aids, it provides particle separation down to the micron range. The patented concept established a new generation of filters that significantly optimise central processes in the metal-working industry.
Process belt meshes / Conveyor belt meshes
As a core component in a wide range of production processes, process belts manufactured by the GKD business unit Process belt meshes play an indispensable role in industry. The quality, construction and lifetime of GKD belts are decisive factors for efficiency and cost-effectiveness. Woven plastic process belts are primarily used in solid/liquid filtration in belt filter presses or vacuum filters in fruit juice production, sewage sludge drainage and phosphor extraction. Woven metal process belts made of stainless steel or bronze – also in combination with plastic – are core products for freezing, drying, draining or heating processes. Pizzas are baked on them, mashed potato flakes are dried on them, fruit and vegetables are frozen on them. Self-steering TRACKMATIC® belts made of stainless steel or blends of plastic and metal have proven themselves in textile finishing and in nonwovens production, as well as in the processing of wood and ceramics. Especially in the fast-growing technical textiles market, GKD process belts and meshes set standards for glass, synthetic, mineral and cellulose fiber nonwovens, and in refining, forming and coating processes. In the wood-processing industry, too, process belt meshes made by the Düren-based company are well-established products. Process belts made of metal, plastic or material combinations are used all over the world in the chipboard, fiberboard, laminating and verneering as well as in the pellet manufacturing industries. With a wide and versatile range of proven constructions and promising product innovations, GKD relies in its business unit Process belt meshes on a consistent niche policy in quality-conscious target markets.
Up to 1992, few people were aware of the existence of GKD woven metallic and plastic meshes, although they were in use all over the world. The first decorative use to which they were put was as radiator grilles made of aluminium mesh. It was the beginning of the cooperation with the French architect Dominique Perrault in 1993, a collaboration which has continued for over twenty-five years now, which marked the birth of GKD`s business unit Architectural meshes. In their first mutual architectural project, the Bibliothèque Nationale de France, GKD explored the potential for woven metallic materials for architecture and realized the production of meshes for twelve different areas of application. Wire mesh panels in widths of up to eight meters make this possible in the dimensions of even the largest-scale architectures. Apart from the weavable width and the variety of materials supplied by GKD, the success of woven wire mesh in architecture is also due to its optical and functional properties: reflectiveness, transparency and opaqueness, flexibility and robustness, permeability to light and air, practically unlimited service life, ease of cleaning, recyclability and functional protection against the sun, draughts, impacts and above all against blast waves and flying fragments from bomb detonations. Reference projects around the world include office and government buildings, museums, hotels, airports and railway stations, cinemas, carparks, bars, restaurants and boutiques, and even sports stadiums and bridges. The variety of applications ranges from external façades, ceilings, walls, partition walls and sunscreen elements to balustrades, column and staircase claddings, floor coverings and object design. Antiturbulence nets for aerodynamic applications, for example, in wind tunnel constructions in the automotive and aerospace industries, are further successful areas of application for GKD meshes.
Other milestones in the success story of the business unit Architectural meshes after the Bibliothèque Nationale de France include the Cycling Arena and Indoor Swimming Pool in Berlin. In the Bibliothèque Nationale, the versatility of GKD mesh's application potential first became apparent, while the roofs of the two sports halls in Berlin demonstrated its capacities for coverage of immense surface areas. The façade of one of Europe's largest carparks, accomplished at Cologne/Bonn Airport by Murphy/Jahn, set standards for these areas of application. The optically seamless cladding of a round object was achieved for the Bertelsmann pavilion "Planet-m" at the Expo 2000 in Hannover. The "external skin" of the Expomedia Light Cube in Saarbrücken counts as one of the wire mesh façades with the largest individual elements ever installed. Today, the reference list includes the world's most prominent architects and internationally renowned buildings all over the globe. Among the latest spectacular architectural accomplishments using GKD architectural mesh are the Louis Vuitton Flagship Stores in Tokyo and Rio de Janeiro, Real Madrid's Estadio Santiago Bernabéu, the Formula One racing circuit in Shanghai, the Beijing Opera, the tennis stadium in Madrid, the American Airlines Arena in Miami or the Pavilion Dufour at the Castle of Versailles. Consistent expansion of the product's aesthetic-functional range of use will continue to characterize this sector of the company.
