2, 3 or 4 turned folded edges, with height starting from 1 cm and angle between 30° and 120°.
The standard perforation is obtained with a 2-mm and 3.5 mm pitch. According to our research, such dimensions grant an optimal cooking and anti-adhesive ratio.
The edges are designed with non-perforated rigid band, in order to guarantee more robustness.
Flat aluminium baking trays may be used in freezers or proving chambers without any negative impact.
