Materials and processes: an exercise in perfection
SL Rasch has earned an outstanding international reputation for its extraordinary structures – which include the biggest clock tower in the world, sliding domes for the Prophet’s Mosque in Medina and a ring-shaped bridge structure made of carbon fibre composite in Mecca. We implement our hi-tech structures in collaboration with highly specialised companies from our local area in southwest Germany, as well as with international partners from Japan, the United Arab Emirates, Turkey, Switzerland, Austria, Malaysia, Italy, India and many other countries.
Again and again, our projects present new challenges for us to solve – challenges that we use to perfect our materials and processes. In addition to classic building materials like steel, concrete, natural stone and wood, we also use ultramodern options such as glass fibre fabric, carbon fibre composites or plastics like PTFE. Most of these materials not only reduce weight but increase stability as well.
Exceptional structures call for special materials like carbon, carbon fibre and glass fibre.
Carbon fibre is a particularly stiff and lightweight material. It is therefore suitable for a great many ultra-lightweight structures – as are aramid and other textile materials. However, because some of them are not UV-resistant, SL Rasch has developed a robust and exquisite system for using them in building construction: the finished fibre composite components are protected by a layer of glass mosaic tiles. Glass fibre materials are used for applications like structural facade components or flexible envelopes for tent structures.
Once the fibre composite components on the great clock tower in Mecca have cured, they are covered with a protective layer of glass mosaic tiles that echo ornaments from traditional Islamic architecture.
