It is a well insulated folding door especially developed for demanding industrial environments. High flexibility makes it possible to install this door in almost every type of building.

The door is made of aluminum tubular profiles, profiled steel sheets and injection moulded foam to make a stable sandwich construction. The door can be installed on either the inside or the outside of the exterior wall. A wide range of options is available to suit the appearance of the existing building. The Crawford 521 folding door has been designed to meet all operational and safety requirements in the European Directives and the standards issued by the European Standardization Committee, CEN. Reliability The Crawford folding door program has been developed in accordance with the ISO 9001 Quality Assurance System and the ISO 14001 Environmental Management System.
