Why this accessory earns its place
Aluminium is the choice for high-volume kitchens. It heats fast and distributes heat evenly across the tray surface, so items cook consistently whether they're on the edge or the centre. The material is rigid enough that repeated use — thirty bakes a day, hundreds a month — doesn't bow the sides or dent the flat. And it's light enough that a cook can move a hot-loaded pan from oven to cooling rack without arm strain.
Robustness means the tray handles abrasion in the oven and the pass. Rubbed against the oven cavity? Aluminium scuffs but doesn't crease. Years of use in a professional kitchen accumulates marks, but the tray stays functional. The flat base sits level on the oven rack, and the walls stay parallel — no rocking or tipping a half-set dough mid-bake.
A 2/3 gastronorm fits into standard ovens and prep counters. Stack three trays and they nest flat for cooling and storage. The tray is rated for standard baking temperatures — breads, pastry, vegetables — and survives thermal cycling (in at 220°C, cooling on the rack, wash, back in again) without fatigue.
