Regardless of how and where system 20 is used, it always satisfies even the toughest quality standards, right down to the last detail. The elements' supporting structure is made of a special bulthaup aluminum alloy and stainless steel, which complement each other perfectly in accordance with their static function. Stainless steel is used everywhere that influences such as moisture, extreme heat or impact can affect the surface. It ensures long-lasting durability and hygiene. Aluminum, on the other hand, weighs less and is very easy to process. One special detail of system 20 is the pylon. It is the supporting proof of the unity of form and function. This unique solution of combining a flat surface with a rounded foot gives the elements their characters. What's more, it's extremely stable. The individual parts of system 20 are bonded using a force-fitting method and a technically sophisticated gluing system, while the feet and rear panels are screwed on. Because the bonding of the three different materials of aluminum, stainless steel and die-cast zinc is not without problems, in view of their different properties and coefficients of expansion, they are joined together at bulthaup under the influence of heat. Even heating is ensured by the method known as induction.
