Tempered Processing

· Glass thickness from 1/8" through 3/4" can be tempered.
· Glass thickness from 1/8" through 1/4" are commonly heat-strengthened.
· All processing work such as cutting, edgeworking and rilling must be completed pior to tempering.
· GTI tempered glass can be processed in a variety of different styles, from the relativley simple ground or polished edges.
· Holes must be the same size or bigger than the glass thickness. Minimum diamter for 1/8" glass is 3/16".
· Contact your local sales rep about other limitations regarding holes, notches, & cutouts.

There are some characteristics of tempered glass, such as bow & warp, roller distortion, and others, that are inherent to the tempering process, and are not considered defects.
