Our passenger elevators help passengers reach their floors quickly, comfortably, and safely. For tenants, they provide quiet operation, which is especially important at night. For architects, they are easy to integrate into designs and help optimize available building space. For building owners, they help reduce total lifetime costs by providing excellent maintainability and reduced energy consumption. Spacious elevator cars enable passengers and their luggage, or staff and their equipment, to travel comfortably and efficiently through the buildings.

PC (Polycarbonate) is a type of engineering plastic known for its excellent mechanical and thermal properties. It's often referred to as PC material, with specific types like PC 136 or 21666664 being commonly used in industrial applications. Widely adopted around the world, PC offers a range of benefits, but it also has some limitations that are important to consider.
One of the key features of PC is its amorphous structure, which gives it good electrical insulation, dimensional stability, and resistance to chemicals. It can withstand high temperatures up to 160°C and remains functional at low temperatures down to -60°C. Additionally, it’s flame-retardant, non-toxic, and can be easily colored, making it suitable for a wide range of uses. Its transparency and durability make it ideal for products ranging from mobile phone cases to bulletproof glass.
Despite its strength and toughness, PC is not as hard as metal, so it can be prone to scratches. However, it can handle heavy pressure and general impacts without breaking—unless subjected to extreme force, such as being hit with a stone. It can even be manufactured in large diameters, up to 600 mm, and is resistant to both acids and alkalis.
In the construction industry, the term "PC" can have two different meanings. The first refers to "Prefabricated Concrete" or "Precast Concrete," which involves using pre-made concrete components in construction projects. The second meaning is "Prestressed Concrete," which relates to structures where tension is applied before the load is added. These two interpretations are often confused, so it's important to clarify the context when using the term.
PC tubes, also known as polycarbonate tubes, are a type of transparent plastic tubing. They are known for their high light transmission—up to 92%—which gives them the nickname “plastic crystal.†They are highly weather-resistant, especially for outdoor use, and offer good surface hardness and luster. Their versatility allows them to be molded into various shapes and sizes, making them popular in both industrial and consumer applications.
