1.Since ribbed glass is a type of rolled glass and its surface is not as flat as float glass, care must be taken during the tempering process. If the glass is placed with its flat surface facing downwards, it can result in white flaky abrasions due to contact with the roller. Therefore, when tempering, the glass should be positioned with its striped surface facing downwards.

2. Ribbed glass sheets are subjected to compression during production, requiring longer heating times during tempering. If not heated sufficiently, the glass is particularly prone to breakage after tempering. Moreover, the heating time for ribbed glass should be set based on the thickest part of the glass, as failing to do so means the entire sheet may not reach the softening point necessary for tempering.

3. Due to the uneven thickness of ribbed glass, it's essential to set the tempering wind pressure based on the thinnest part of the glass. If this isn't done, the glass will not achieve the desired fragmentation and the necessary tempering stress after the process.
