Perforated materials combine practicality and aesthetics
They offer extensive application possibilities – from refined architectural detailing to demanding technical solutions in industrial environments.
Applications:Suspended ceilings
Thanks to their technical properties, attractive appearance and ease of installation, suspended metal ceiling systems are widely used in offices, administrative buildings, universities, schools, hospitals, retail outlets, supermarkets, cultural centres, airports, railway stations, showrooms, production halls and warehouse facilities.
Ceiling systems can incorporate lighting, fire detection sensors, security systems, and audio equipment, and may be integrated with ventilation components.
A practical benefit is the concealment of the concealment of mechanical and electrical services and the option to reduce the clear ceiling height of the space.
Applications:Facades and cladding
Perforated sheets, expanded metal, and gratings are used in façade systems for a wide range of buildings, including office centres, shopping centres, schools, sports halls, residential complexes, and car parks. Owing to their durability, versatility, and visual qualities, metal façade systems allow extensive design expression while fulfilling protective, shading, and ventilation functions.
They contribute to long service life, minimal maintenance, and improved energy performance through light regulation and ventilation.
Applications:Fencing
Fence infill panels can be manufactured from perforated sheets, expanded metal, or laser-cut sheets, most commonly in aluminium. A wide range of patterns and colours enables coordination with the architectural concept of the building. Metal fencing is low-maintenance, durable, and provides a functional as well as representative solution for private houses, residential developments, and commercial premises.
Applications:Balcony and other infill panels
Perforated sheet and expanded metal are suitable for balcony and terrace infill panels, balustrades, and the covering of structural openings. They provide safety, airflow, and an attractive appearance, with the option to adjust transparency and shading levels.
They are characterised by high strength, long service life, and minimal maintenance requirements.
Applications:Stairs and gratings
Stair treads and gratings are used in industrial facilities, technical buildings, and architectural projects. The range includes steel and stainless steel options, as well as variants in expanded metal or perforated sheet, enabling both technical and design solutions for interior and exterior use.
Anti-slip finishes and various surface treatments ensure long service life and reliable performance.
Applications:Balustrade infill panels
Perforated sheets and expanded metal are used as balustrade infill panels in both interior and exterior applications, combining safety with visual appeal. A wide selection of perforation patterns and surface finishes enables alignment with the architectural concept of the building.
