The companies listed below sell equipment designed for the production of metal profiles, which are mostly intended for the construction industry. However, in addition to the production of the final products specified in the table in this guide, their use may include other types of applications, such as the production of furniture – cabinets and shelves, for example. Machines in this class can process galvanized and uncoated steel sheets, as well as aluminum, and have a variety of configurations, including compact models designed for the production of small batches and large roll forming machines, which may have auxiliary equipment. In the latter case, a typical formatting observed in the metalworking industry is the implementation of uncoilers, cutting, punching and stamping tools, lubrication and planing systems, as well as rewinding and part storage devices. One of the main characteristics that distinguishes these equipment is their number of stages, called “castles”, which is determined according to the complexity of the profiles to be manufactured. Furthermore, according to the companies listed in this guide, PLC and HMI systems can be integrated into the set.
