Flat glass is heated until red hot, carefully formed to the desired shape, then tempered by super cooling to trap high energy within the glass. The resulting bent tempered glass has up to a fourfold strength increase compared to annealed glass of the same thickness and if broken, breaks into an innumerable number of relatively small fragments of more or less cubicle shape.

This product begins as flat glass commonly selected from the broad
range of commercial float products including clear, ultra clarity low-iron, grays, bronzes, greens, and blues. The surface may have a reflective, low-e, self-cleaning, or other pyrolitic coating. Specific colors and coatings are often known simply by the brand names assigned by primary glass manufacturers8. We also process patterned, stained, cast, glue-chip, ground, and acid-etched glass. These flat pieces are CNC processed and then undergo the complex processes to create bent tempered glass2.


We offer bent tempered glass in 1/4" to 3/4" thickness5. Options include shape cuts, sandblasting, silkscreen ceramic frit, holes, notches, cutouts, and edge finishes such as seamed (sanded), arris flat polished, flat ground, pencil polished, bevel polished, or angle mitred. Its indoors surface can be conditioned with a solid ceramic frit or fallout-resistant silicone to create a spandrel panel3.

The bent tempered glass possible includes that within the broad range of sizes and radii referenced in the capabilities table1. The table also references special capabilities for jumbo sizes, tight radii, and bends over 90 (quarter circle) to as large as 180 degrees (half circle). Adjoining individual pieces with different radii, reverse installations, and flat glass allows the creation of unique shapes6.

Our bent tempered glass conforms to the applicable criteria of ASTM
C1464, C1048, and C1036.

WARNING: Tempered glass meeting the requirements of CPSC 16 CFR 1201 and ANSI Z97.1-1984 is defined as a SAFETY GLASS PRODUCT for architectural safety glazing in the United States of America. Only glass fabricated by Precision Glass Bending, and issued with an individual permanent logo or certificate stating it has been tempered in conformance with these requirements, is certified to be tempered with the category I & II safety designation.

WARNING: All tempered glass can experience spontaneous breakage. If broken, tempered glass falls out of it’s opening in interlocking clumps. For this reason, we recommend against using tempered glass for glazing above populated areas in commercial buildings and skylights in homes. Tempered glass can, on occasion, break into large shards rather than the classic tiny piece pattern.

WARNING: Tempered glass meeting the requirements of FMVSS 205, AS-2 (10-1-00) and ANSI Z26.1-1980 Item 2 is defined as a SAFETY GLASS PRODUCT suitable for AS2 motor vehicle safety glazing in the United States of America. Tempered glass that meets the requirements of FMVSS 205, AS-3 (10-1-00) and ANSI Z26.1-1980 Item 3 is defined as a SAFETY GLASS PRODUCT suitable for AS3 motor vehicle safety glazing in the United States of America. Only glass fabricated by Precision Glass Bending, and issued with an individual permanent logo or certificate stating it has been tempered in conformance with these requirements, is certified to be tempered with the respective AS2 or AS3 safety designation.
