Custom configuration based on opening dimensions, drawings, performance requirements and destination market.
High speed doors open and close in seconds to keep traffic moving and to limit air, dust and temperature exchange between areas. They suit logistics buildings, workshops and production facilities where a door cycles many times a day. Configuration follows opening size, cycle frequency and the conditions on site.
