Each door is designed from scratch based on customer requirements, such as measurements, location and wind resistance. This can be up to 280 km/h (on demand). It can be designed both for installation in new buildings, as well as for adaptation to existing buildings, as well as both inside and outside the building. A work of adaptation of the structure must be done together to be able to fix the door correctly. Its double canvas with reinforced internal structure allows it to cover large gaps and offer high wind resistance
