Roller shutter doors are made from high-strength steel or aluminum sheet profiles and are used for industrial buildings, shops and many other applications.
They are technical profiles which are subject to opening and closing stress at least once a day. Their height and shape can differ greatly. In fact there are flat, curved, perforated and double-wall slats. With the DALLAN COMBI technology, DALLAN systems are extremely versatile and guarantee the manufacture of products that always work properly and look good.
