Saildoor® is a new concept of industrial closure, unique in its kind for attitude and performance.

High-speed fold-up door

A high-speed fold-up door conceived, designed and built to measure for the closure of big industrial openings. Wind resistance, reliability and maintenance ease characterize Saildoor® as a unique product in the world scene.

Saildoor® closure boasts the highest class of wind resistance, that is class 5 of the UNI EN 12424 standard, and it has been certified according to UNI EN 12444 Ch. 7.1, which certifies the resistance of the whole structure. The materials with which it is made tolerate temperature changes and atmospheric agents, making Saildoor® suitable for the most difficult contexts.

The particular structure allows a simple and quick maintenance thanks to the placement on the ground of the mechanical components.
Saildoor® ranks among the most sensitive solutions to the environmental impact. This is made possible by low energy consumption and with a high opening / closing speed guaranteeing significant savings in terms of air conditioning.
