High-quality, sustainable, safe and efficient

Our BUG Aluminium-Systeme brand offers solutions for windows and doors as well as façades and flat roofs tailored precisely to your requirements. You get assembly-ready product accessories and custom aluminium components for your specific construction design. Our production and processing facilities produce extrusion-pressed aluminium profiles in high, Made-in-Germany quality, covering the entire value creation chain.

Did you know that the light weight of aluminium minimises the bearing load of structural components in the construction industry? As a lightweight metal, aluminium offers a high strength-to-weight ratio which provides excellent safety and stability in the construction industry. What’s more, the silver-coloured metal gives you flexible design options. Its natural corrosion resistance gives aluminium high durability. These properties combined with our manufacturing depth and comprehensive finishing options ensure our products offer lasting, reliable protection against weathering, climate damage and other environmental effects. Once they are installed, the aluminium products we develop meet the highest quality and sustainability requirements. Together our aim is to help you realise your vision in all your structures, building and construction projects! Simply contact our experts for the construction industry
