NL LINE The blades are made from strips mainly of prepainted aluminum.
Alternatively on specific requests in painted galvanized steel, stainless steel, rheinzinck, copper.
Starting from strips of different widths and thicknesses depending on the size of the blades, they are made by press-bending to achieve the ellipsoidal shape and are stiffened by internal aluminum profiles.
Finally, they are closed at the end by die-cast aluminum end caps.
Feasible widths are mm 230, mm 285, mm 350, mm 470, mm 585, mm 650.
They can be mounted vertically and horizontally, fixed or swiveling with electric actuators.
