Leaf consisting of a set of bars made of profiled steel sheet of 20x3mm, construction in the ‘X’ (cross) lattice.
The ‘X’ (cross) lattice leaf slides through top fixed rollers (bearings), which work inside of U-shaped metal profile, allows a soft and convenient functioning.
The retractable grilles open like a harmonium to the left, to the right or in two leaves with opening in the middle. To have a full clear passage, use the hinge aside and the leaf can fold to the side after being opened. The bottom track can be folding or removable to facilitate the entry.
All galvanised steel construction, with option of powder-coated paint in a RAL colour chosen by the customer.
