Important information for measuring the trays: The baking trays fit various ovens as a replacement or as a compatible accessory for brands such as Siemens, Bosch, Neff, AEG, Elektrolux, Zanker, Whirlpool, Bauknecht. When choosing the size of the perforated sheet, it is important to consider the insertion dimension for the perforated trays in the oven, not the absolute inner dimensions of the stove. Often wire racks are attached to the edge of the oven for guiding the baking trays, which can limit the available space for the perforated plate. To determine the correct size of the perforated sheet, please measure between the two guides in the oven and not on the oven wall. It is even easier if you measure an already matching perforated plate. Please note: it is possible that certain scratch marks occur during production, as is common in the production of professional baking trays. However, these scratches do not affect the quality of the sheet or the baking result. The perforated sheets are made of aluminium and have a fine perforation, so they may warp slightly when heated. This often occurs when frozen products are baked on the trays or the baked product is too large. As a result, the heat is distributed unevenly, which often leads to bending of the sheets. However, after cooling, the sheets return to their normal shape. With a LEHRMANN perforated sheet, you can prepare healthy and crispy bread as well as pizza, tarte flambée and vegetable chips. The baking of delicate yeast pastries, chiabatta, crispbread, pretzels, cookies is also excellent on a perforated plate.
