Proven by years of bakery application experience, 0.6mm aluminized steel features thin alloy and aluminum layers and tends to deform after long-term use. From a long-run cost perspective, 0.7mm & 0.8mm trays deliver better economy. Though 0.6mm trays come at a lower upfront cost, thicker 0.7/0.8mm options perform far more steadily with anti-warp properties, superior heat conduction and around one-third longer service life.
