We have been tempering glass in-house since 1991 to ANSI Z97.1 standards. We strive to produce glass that is free of pits, scuffs, heat stains and warping. It is important to us to know what your application is, and what your expectations are. Our oven rollers are cleaned on a regular basis, and our tempering schedule is prioritized so glass that absolutely needs to be perfect comes first in the cycle. We temper glass from 3/16" thick to 3/4" thick. You are always welcome to bring us your fabricated glass for tempering.
