Flat glass is heated until soft, carefully formed to the desired shape, and then annealed by controlled cooling to minimize trapped energy within the glass. The resulting bent annealed product offers un-enhanced strength and the stability of minimized internal stresses, but if broken, breaks in a traditional large fracture pattern.

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 sheets are CNC fabricated and then undergo the complex processes to create bent annealed glass7.

We offer bent annealed glass in 3/32" to 1" thickness5. Options include shape cuts, sandblasting, silkscreen ceramic frit, holes, notches, cutouts, and edge finishes such as clean cut, seamed (sanded), arris flat polished, flat ground, pencil polished, bevel polished, or angle mitred.

   

The bent annealed glass possible includes that within the broad range of sizes and radii referenced in the capabilities table1. The table also references special capabilities The table lists 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 annealed glass conforms to the applicable criteria
of ASTM C1464 and C1036.

WARNING: Annealed glass is designated a NON-SAFETY GLASS PRODUCT
unless permanently assembled in a certified laminated glass, as alone it does
NOT meet the requirements of CPSC 16 CFR 1201 and ANSI Z97.1-1984 defining
safety glass products for architectural safety glazing in the United States of
America. Annealed glass must NEVER be used in those instances where safety
tempered or safety laminated glass is required by the law, thermal or mechanical
loads, or applicable codes.
