One piece or thousands, Custom Glass Industries is your source for Architectural & Interior applications.

Tempered glass is often referred to as “safety glass.” And for good reason - it’s more resistant to breakage than normal float glass. And if it is broken, it usually breaks into relatively small particles, which are less likely to cause injury.



  • Approximately five times stronger than annealed glass of equal thickness
  • Greater resistance to thermally-induced stress than heat-strengthened or annealed glass
  • Suitable for use as a safety glass
  • Tempered safety glass is also mandated in other parts of the world by individual country regulations or specifications


  • Suitable where safety glazing is required
  • Fire knock-out panels
  • All glass entrances and storefronts
  • Extreme wind loads
  • Fireplace enclosures

How to Measure Bent Glass

Here are 4 Easy Steps, ensuring that we have all the correct measurements for your project:

A chord is a straight line between two points on a curve or circle. As it applies to a piece of curved glass, the chord we are wanting to measure is the distance between the two end points of the curve. Please measure the chord for the outer surface. We are not interested in the inside surface, as our bending machine is always bending glass to the outside surface.

Take the value measured in step 1; Divide this number by two, and you will have the mid-point of the curve.

From the measurements acquired in steps 1 and 2, we are now able to make additional measurements and calculations. Since we are relying on the accuracy of the chord and mid-point measurement for the next steps, it should be apparent how crucial these initial values are, to the over-all process. Feel free to re-measure often, to ensure 100% accuracy.

The depth of the curved surface, also known as the off-set, represents the maximum distance that the curved surface reaches from the chord. In other words, it is the “depth” of the bent glass we will be producing for your project. Place a solid piece of wood or metal firmly against the two end-points, the same end-points from which you measured the chord. Measure a-long this beam and mark the mid-point (as determined in step 2). Place a right-angle ruler at the mid-point of the chord and measure the distance from the mid-point to the outer surface of the curve.

The reason for using a right-angle ruler against a solid surface is for maximum accuracy. Simply eye-balling the right-angle with a straight ruler, or taking the measurement from a flexible surface at the chord, risks inaccuracies that could cause your custom glass to fit incorrectly.

The Height is the easiest measurement of all. Using a metal measuring tape, measure the distance from the very top, to the very bottom of the application for which the curved glass piece is intended.

With this info, our knowledgeable staff can calculate the radius and arc length for any given project.
